This makes the Qt terminal compatible with OS X. 2012-01-17 Ethan A Merritt * src/eval.c (update_plot_bounds): Store the canvas size used by the previous plot in user accessible variables GPVAL_TERM_XSIZE, GPVAL_TERM_YSIZE. 2012-01-15 Mojca Miklavec * src/mouse.c (event_buttonpress): Treat mouse buttons 6/7 as left/right scroll events (e.g. from fingers on a touchpad). * src/qtterminal/QtGnuplotScene.cpp (mouseReleaseEvent): Pass horizontal scroll events through to gnuplot core as mouse events 6/7. 2011-01-15 Bastian Maerkisch * config/config.mgw: Sync with configure. 2011-01-14 Bastian Maerkisch Installer for Windows. Japanese translation by Shigeharu Takeno. * win/gnuplot.iss win/modpath.iss: Installer script to be compiled by Inno Setup. New files. * win/Copyright-ja.txt: Japanese translation of Copyright, includes original text. Encoding is Shift-JIS. * win/README-Windows.txt win/README-Windows-ja.txt: New files, displayed by installer before installation. Based on Tatsuro Matsuoka's README.Windows.gpteam and README. * config/mingw/Makefile: New make target 'installer'. * Makefile.am (EXTRA_DIST): Include win/ 2011-01-14 Bastian Maerkisch * tutorial/linepoin.plt: Avoid deprecated syntax. * config/mingw/Makefile config/msvc/Makefile src/plot.c: GNUPLOT_SHARE_DIR is relative to gnuplot directory on Windows. Extend build support for documentation, include in installer. 2012-01-11 Ethan A Merritt * src/util3d.h src/util3d.c (edge3d_intersect two_edge3d_intersect) src/graph3d.c (plot3d_lines_pm3d): The utility routines in util3d assumed that a 3D curve is always traversed in ascending order of the constituent points. But plot3d_lines_pm3d scans in both directions, leading to incorrect clipping and possible array over-run when the utility routines were called. Furthermore, the arrays holding the scan direction info were never initialized. Bug #3471163 2012-01-08 Ethan A Merritt * src/plot.c: Allow shell commands from ~/.gnuplot but not from shared initialization files. * configure.in: Report status of aquaterm configuration correctly (Lutz Maibaum). 2012-01-07 Jérôme Lodewyck * src/qtterminal/QtGnuplotScene.cpp: Normalize the zoom rectangle to avoid redrawing artifacts 2012-01-07 Ethan A Merritt * src/misc.c (lf_pop): If the current input stream from "load file" is really a pipe, close it with pclose() rather than fclose(). Bug #3470351 2012-01-07 Jérôme Lodewyck * src/qtterminal/QtGnuplotScene.cpp: Normalize the zoom rectangle to avoid redrawing artifacts 2012-01-05 Ethan A Merritt * configure.in src/Makefile.am: Tweak autodetection of Qt utilities to handle differences in the Qt 4.6 and 4.7 pkg-config files. * src/set.c: Call gp_expand_tilde() in 'set loadpath' and 'set fontpath'. 2012-01-04 Ethan A Merritt * src/hidden3d.c: Fix an uninitialized colorspec found by valgrind. The trigger was hidden3d handling of '... with labels tc palette'. 2012-01-02 Ethan A Merritt * configure.in term/qt.trm In src/qtterminal: QtGnuplotEvent.cpp QtGnuplotEvent.h QtGnuplotItems.cpp QtGnuplotItems.h QtGnuplotScene.cpp QtGnuplotScene.h QtGnuplotSettings.ui QtGnuplotWidget.cpp QtGnuplotWidget.h qt_term.cpp qt_term.h README.Qt: Update qt terminal to support pointsize, dashed lines, round linejoins, term->layer(), LT_BACKGROUND, mouse toggling, faster rendering. 2012-01-01 Ethan A Merritt * src/qtterminal/QtGnuplotApplication.cpp (processEvent): * src/wxterminal/wxt_gui.cpp (wxt_atexit): In "persist" mode, if all qt plot windows were already closed when the main program exited then the daughter process would become a zombie. Even worse for wxt; if _any_ plot windows had been closed then the persisting daughter process would become a zombie. Bugfix. 2011-12-29 Ethan A Merritt * src/plot.c src/plot.h src/qtterminal/qt_term.cpp: Provide a function cancel_history() that can be called by terminal helper processes after forking so that the history file isn't trashed on exit. Bug #2950711 * docs/gnuplot.doc: Minor updates to match 4.6 configuration. 2011-12-28 Ethan A Merritt * docs/gnuplot.doc share/Makefile.am share/colors_default.gp share/colors_mono.gp share/colors_podo.gp share/gnuplotrc src/Makefile.am: Provide template initialization files, including examples of customizing the linetype color sequence. These are installed in $GNUPLOT_SHARE_DIR (usually /usr/local/share/gnuplot/4.6). * src/command.c src/datafile.c src/help.c src/history.c src/misc.c src/plot.c src/plot.h src/term.c src/variable.c: Do not allow execution of system(), shell, or popen() commands in the initialization files. * src/plot.c src/show.c: More compact splash page. * src/graphics.c src/graphics.h src/graph3d.c: Strangely, the final parameter of place_objects(,,,clip_area) was (1) never used and (2) shadowed a global parameter that _was_ used. Bug #3426247 * configure.in: Default to --enable-stats --without-bitmap-terminals * configure.in PATCHLEVEL: Report as version 4.6.rc1 2011-12-25 Ethan A Merritt * src/qtterminal/QtGnuplotEvent.cpp src/qtterminal/QtGnuplotScene.cpp: If two button release events occur in quick succession then the program messes up the event handling and winds up in a non-recoverable state. Apply an empirical fix to ignore events in a 300 msec window. Also rather than ending up a zombie, exit explicitly on a sync error. Bugfix 2011-12-21 Ethan A Merritt * src/plot2d.c: The default sequence of histogram colors was one off from the default sequence of line colors. Bugfix. 2011-12-11 Bastian Maerkisch * config/config.nt config/config.mgw: Sync with config.h created by autoconf. * src/msvc/Makefile: More complete install target. Add new variables to hold paths to external libraries. * src/mingw/Makefile: Include index in gnuplot.pdf. Support building of the Japanese help file wgnuplot-ja.chm. * src/eval.c (update_gpval_variables): New variable GPVAL_ENCODING. * term/gd.trm (gd_iconv): Silence const mismatch compiler warning in call to iconv by casting second argument to (void *). * src/syscfg.h: All tested platforms (XP, Vista, 7) support '/' as directory separator. * src/win/winmain.c: Automatic language detection can be overridden by new setting "Language=XX" in wgnuplot.ini. Suggestion by Shigeharu Takeno. * src/win/wpause.c: Remove local definition of TBOOLEAN. * docs/plotstyles.gnu: Prefer pngcairo over png terminal. Use font "Times New Roman" on Windows. * demo/random.dem: Use loops to create random number data sets. 2011-12-08 Ethan A Merritt * docs/gnuplot.doc docs/Makefile.in term/context.trm docs/doc2rnh.c: Miscellaneous documentation updates, remove dead URLs. * configure.in docs/gnuplot.doc src/plot.c src/show.c config/config.cyg config/config.dj2 config/config.mgw config/config.nt config/config.os2 config/config.oww config/makefile.unx: Despite what it says in the documentation, and despite what the configure script prints out, auto-configuration never defined the NOCWDRC flag to disable reading an initialization file .gnuplot from the current directory. This is a security risk. Furthermore, having to define something special to get the secure state is bad design. Fix the configuration script and default to not initializing from the current directory. Put a warning in various config files. 2011-11-29 Shigeharu Takeno * docs/Makefile.in: Remove duplicate entry for qt in CORETERMS. 2011-11-28 Ethan A Merritt * src/scanner.c (legal_identifier) src/scanner.h src/stats.c: Make sure that the variable name produced by the "stats ... prefix" command is a legal identifier. Bug #3441395 * src/set.c (set_palette): Add missing check for conflicting options. 2011-11-26 Ethan A Merritt * term/cairo.trm: Revert the change of 2011-08-25 that tried to skip empty vectors. The concept was sound but the implementation was not correct, leading to mysteriously missing lines. Bugfix. 2011-11-24 Ethan A Merritt * src/term_api.h src/misc.c src/hidden3d.c: New flag LT_SINGLECOLOR passed through to hidden3d to indicate that the user gave an explicit surface color in the splot command. Bugfix. 2011-11-22 Ethan A Merritt * Branchpoint for 4.6 cvs tag -b branch-4-6-stable 2011-11-22 Ethan A Merritt * src/contour.c (contour): Format contour labels using gprintf rather than sprintf so that LC_NUMERIC and "set decimal" are honored. Bugfix. * term/js/gnuplot_svg.js: Try to correct for coordinate offset due to scrollbars. The fix is unfortunately browser specific. 2011-11-22 Peter * term/svg.trm: "standalone" option includes gnuplot_svg.js mousing support directly in the output *.svg file rather than linking to it as an external resource. 2011-11-18 Daniel Leidert * demo/html/webify.pl demo/html/webify_svg.pl demo/html/webify_canvas.pl Use perl5 native routine ctime() rather than perl4 external module. * src/datafile.c term/epson.trm term/post.trm: Typos. * configure.in: Check for lua5.1.pc if lua.pc is not found. * man/gnuplot.1: Add some needed character escapes. 2011-11-18 Bastian Maerkisch * src/win/wgdiplus.cpp src/win/wgdiplus.h src/win/wgnuplib.h src/win/wgraph.c src/win/wresourc.h: Antialiasing of fill patterns. * src/win/wgraph.c (CopyPrint): Use Print Setup dialog since the Page Setup dialog does not offer a possibility to change printer. Do not use antialiasing on printers. 2011-11-15 Bastian Maerkisch * src/win/wgnuplib.h src/win/wgraph.c term/win.trm: Store current text encoding in list of drawing ops. 2011-11-15 Ethan A Merritt * src/axis.h src/axis.c (parse_range, parse_named_range) src/axis.c (save_writeback_all_axes check_axis_reversed) src/fit.c src/plot2d.c src/plot3d.c src/stats.c src/unset.c: Replace axis-related macros with equivalent subroutines. 2011-11-14 Ethan A Merritt * config/Makefile.am.in demo/Makefile.am.in m4/Makefile.am.in tutorial/Makefile.am.in term/Makefile.am.in: Make sure that the generated files Makefile.am and gnuplot-tikz.help do not end up non-writable by the owner, which caused build cleanup problems while packaging. Bug #3419881 2011-11-14 Peter Juhasz * src/plot2d.c (store2d_point): Fix for 4-column mode of BOXPLOT style which did not handle log scale correctly. 2011-11-14 Bastian Maerkisch * src/win/wgnuplib.h src/win/wgraph.c src/win/winmain.c src/win/wtext.c: Localisation support for menu and help files. Files are loaded according to current language settings from files named "wgnuplot-LL.mnu" and "wgnuplot-LL.chm", where LL is the abbreviation of the current language. Fall back to "wgnuplot.mnu" and "wgnuplot.chm" if localised files don't exist. Defaults may be overwritten by new entries "MenuFile" and "HelpFile" in wgnuplot.ini. Choose appropriate default fonts in Japanese environments. src/show.c (show_version) src/win/winmain.h: List correct names of menu and help files on Windows. src/win.trm (WIN_set_color): Immediately translate palette color values to RGB instead of passing them on. This makes it possible to use more than one palettes in multiplots and in different graph windows. Test e.g. with pm3dcolors.dem * src/win/wgraph.c src/win/wresourc.h src/win/wgnuplib.h: Add a separate switch to toggle antialiasing of polygons. * src/win/wgraph.c (Draw_XOR_Text): Implement a 10 year old FIXME: Use proper raster operation instead of double inversion. 2011-11-12 Shigeharu Takeno * src/win/README.win-ja src/win/wgnuplot-ja.mnu: Update and sync with wgnuplot.mnu 2011-11-12 Bastian Maerkisch * src/set.c (set_degreesign): Windows implementation using a Windows API call since iconv() does not understand locales as returned by setlocale(). * src/command.c (help_command): HTML help window need to occlude the text window. * term/win.trm (WIN_filled_polygon): Use boxfill for filled polygons which are actually rectangles. * src/win/wgnuplib.h src/win/wgraph.c: Add support in windows terminal for toggling individual plots on/off by clicking on the corresponding key sample in addition to toggling via toolbar buttons. 2011-11-11 Ethan A Merritt * src/set.c (set_degreesign): More attempts to work around oddities in Solaris locale handling. 2011-11-10 Shigeharu Takeno * docs/gnuplot-ja.doc docs/term-ja.diff: Sync to docs version 1.699. * docs/gnuplot.doc term/be.trm term/cairo.trm term/context.trm term/win.trm: Fix typos. 2011-11-09 Ethan A Merritt * src/axis.c src/command.c src/eval.c src/gadgets.c src/graphics.c src/internal.c src/tables.c src/unset.c src/util.c src/util.h term/post.trm: Fix or remove some FIXMEs. 2011-11-09 Bastian Maerkisch * doc/gnuplot.doc: New terminal driver epscairo. * term/gd.trm: Don't use gd font pointer variables for builtin fonts. 2011-11-08 Ethan A Merritt * configure.in src/set.c: Use nl_langinfo(CODESET) to find the encoding. This hopefully works around non-standard encoding names used by Solaris. * src/wxterminal/wxt_gui.cpp: Toggle for "plot ... with circles" 2011-11-08 Bastian Maerkisch * doc/gnuplot.doc [New features]: Document new cairolatex and revised windows terminal. 2010-11-08 Tatsuro Matsuoka * src/set.c (set_degreesign): Move include of iconv.h to top level. 2011-11-07 Bastian Maerkisch * term/fig.trm: Update help on font option. * term/context.trm: Avoid use of round() because MSVC is still not C99-compliant. New terminal driver cairolatex, which uses the cairo EPS or PDF backend for graphics output and LaTeX text created by functions shared with the epslatex and pslatex terminals. * term/cairo.term term/post.h term/post.trm term/pslatex.trm: New terminal driver cairolatex. Patch #3413095 2011-11-06 Mojca Miklavec Add a context terminal, which creates output suitable for ConTeXt. * configure.in docs/doc2texi.el docs/gnuplot.doc docs/Makefile.in src/makefile.all src/makefile.awc src/term.h term/context.trm: New terminal driver context. Patches #1654807 and #1503836. Feature Request #2815867. 2011-11-05 Ethan A Merritt * src/wxterminal/wxt_gui.cpp src/wxterminal/wxt_gui.h src/wxterminal/wxt_term.h term/wxt.trm: Add support in wxt terminal for toggling individual plots on/off by clicking on the corresponding key sample. 2011-11-04 Ethan A Merritt term/wxt.trm src/wxterminal/wxt_term.h src/wxterminal/wxt_gui.cpp: Add a term->layer() entry point for the wxt terminal. * src/mouse.c src/term_api.h: TERM_LAYER_BEFORE_ZOOM 2011-11-02 Ethan A Merritt * src/util.c src/util.h src/set.c (set_encoding set_degreesign): Provide an internal char sequence degree_sign[] appropriate for the current encoding. Use iconv(), if available, to translate it into the environment's locale after `set encoding locale`. * src/show.c (show_decimalsign): Show the degree sign also, mostly so that people can report problems with the encoding code above. 2011-11-01 Bastian Maerkisch * src/win/wmenu.c src/win/wtext.c: Use proper dropdown menu for Options toolbar item. 2011-10-30 Bastian Maerkisch * INSTALL: Update Windows section. * config/makefile.mgw: Superseded by config/mingw/Makefile. Removed. 2011-10-30 Shigeharu Takeno * config/config.nt config/makefile.nt: Windows console apps support pipes. 2011-10-30 Bastian Maerkisch * config/config.cyg config/config.mgw config/config.nt config/config.oww: Enable stats command. 2011-10-28 Ethan A Merritt * src/color.c (make_palette): Fix segfault caused by initializing a terminal with an "infinite" color palette (colors == 0) when previous terminal had merely a large color palette (e.g. WIN_PAL_COLORS 4096). Bug #3429772 2011-10-24 Ethan A Merritt * src/axis.c src/axis.h src/datafile.c src/fit.c src/mouse.c src/plot2d.c src/plot3d.c src/save.c src/set.c src/setshow.h src/show.c src/stats.c src/tabulate.c src/unset.c term/canvas.trm term/svg.trm: Change the axis structure field from TBOOLEAN axis.is_timedata to an enum {DT_NORMAL, DT_TIMEDATE} field axis.datatype. This is preparation for adding code to implement a new mode DT_DMS (degrees, minutes, seconds) that tracks x and/or y as geographic coordinates. There is no change to the behavior of the current code. 2011-10-22 Ethan A Merritt * term/svg.trm: Friendlier error message, add a tag at the top of the output svg document. 2011-10-17 Christoph Bersch <cbersch@users.sourceforge.net> * docs/doc2texi.el: Handle presence of three nodes with the same key. 2011-10-14 Ethan A Merritt <merritt@u.washington.edu> * src/specfun.c (humlik): Re-order code to avoid accessing an unitialized variable. * term/emf.trm (EMF_put_text): Re-order code to avoid accessing an unitialized variable. * src/command.c (else_command): An else clause might either be processed by if_command() or else_command(). The latter was not correctly updating c_token. * src/misc.c (lf_load): Tie maximum depth of load commands to STACK_DEPTH. 2011-10-13 Ethan A Merritt <merritt@u.washington.edu> * docs/gnuplot.doc docs/titlepag.tex: Revise the sections that describe function plots to mention `set samples`. Allow the table of builtin functions to split across pagebreaks in the TeX documentation. * src/wxterminal/gp_cairo.c: Decrease linewidth used by pdfcairo terminal for pattern fill. This works around what seems to be a pdf bug in libcairo versions through at least 1.10. * src/fit.c (error_ex): Exit via int_error() so that it can walk through the list of XXX_reset_after_error() routines. 2011-10-10 Ethan A Merritt <merritt@u.washington.edu> * src/hidden3d.c: Bump default QUADTREE_GRANULARITY from 10 to 30. At 10, 24% of the CPU time for all.dem is spent in hidden line removal. At 30 this decreases to 12%, for roughly a 10% speed increase overall. 2011-10-10 Peter Juhasz <juhaszp@users.sourceforge.net> * src/datafile.c src/datafile.h src/gadgets.h src/graphics.c src/graphics.h src/plot2d.c src/save.c src/set.c src/show.c demo/boxplot.dem docs/gnuplot.doc: Add new mode for the "with boxplot" plot style. If there is a 4th column in the using spec, the values in it it will be interpreted as the discrete levels of a factor variable. As many boxplots will be drawn as there are different values in the factor column, each boxplot representing part of the dataset. These boxplots are optionally labeled and sorted. New options "separation", "label", and "sorted"/"unsorted" to "set style boxplot" govern the behavior of this new mode. The demo "boxplot.dem" is extended to showcase the new capability. 2011-10-09 Shigeharu Takeno <shige@iee.niit.ac.jp> * src/internal.c (f_sprintf): More complete MSVC++ snprintf() patch. 2011-10-09 Adam Strzelecki <ono@users.sourceforge.net> * src/wxterminal/wxt_gui.h src/wxterminal/wxt_gui.cpp: Work around a number of issues compiling and running wxt with wx 2.9 using 64-bit Cocoa on OSX Lion. All changes are #ifdef __WXOSX_COCOA__. These may not be necessary once Cocoa reaches a stable release. (1) use wxToolbar AddStretchableSpace rather than AddSeparator (2) wx Cocoa does not support logical operators such as wxDC inverse (3) wx Cocoa toolbar icons are blurry unless they are 24x24 (4) wx Cocoa does not define _Bool even though it says it does 2011-10-07 Ethan A Merritt <merritt@u.washington.edu> * src/color.h src/command.c src/getcolor.c src/gplt_x11.c src/save.c src/set.c src/show.c src/tables.c src/tables.h term/post.trm term/x11.trm demo/pm3d.dem docs/gnuplot.doc: New palette option "cubehelix". The is a family of palettes with the general property of combining N cycles of a color-wheel with a monotonic increase in overall intensity. This feature was suggested by Ingo Thies. See: D A Green (2011) "A colour scheme for the display of astronomical intensity images" http://arxiv.org/abs/1108.5083 2011-10-06 Shigeharu Takeno <shige@iee.niit.ac.jp> * src/internal.c (f_sprintf): Always null-terminal a string written by the non-ANSI compliant MSVC++ routine _snprintf(). 2011-10-03 Bastian Maerkisch <bmaerkisch@web.de> * term/win.trm (WIN_options): When searching the list of graph windows the correct test is for window Id. 2011-10-03 Rich Seymour <richseymour@users.sourceforge.net> * term/svg.trm: Look for strings " Bold" and/or " Italic" in font name and set the corresponding properties if found. Patchset #3058920. 2011-10-03 Bastian Maerkisch <bmaerkisch@web.de> * term/post.trm (PS_options): Properly contain new variable in a block. Bug #3417716 * src/Makefile.maint: New target makefile.awc. * src/makefile.all src/makefile.awc: Regenerated to include stats.c. 2011-10-02 Ethan A Merritt <merritt@u.washington.edu> * configure.in src/Makefile.am src/command.c src/command.h src/show.c src/stats.c src/stats.h src/tables.c docs/gnuplot.doc: New command to generate a statistical summary of the data in a file. stats "datafile" [using col1[:col2]] [nooutput] [name "PREFIX"] Data is read from the input file under the control of the same options used for 'plot' commands (e.g. xrange, yrange, using, index, every). The min/max/mean/stddev/quartiles of data from one or two data columns are printed to the terminal and stored in named variables. These variables can be used to modify subsequent plot commands. This code was developed primarily by Philipp Janert and Zoltán Vörös. * demo/html/Makefile demo/html/Makefile.svg demo/html/Makefile.canvas demo/stats.dem demo/all.dem: New demo to exercise stats code. 2011-10-01 Bastian Maerkisch <bmaerkisch@web.de> * term/cairo.trm: Depending on the version, Cairo defaults to cropping eps files to the minimal bounding box. This patch adds support for the {no}crop option to the epscairo terminal. Cropping is prevented by putting two points in background color in opposite corners, or by directly setting the bounding box for Cairo newer than 1.11.0. * config/mingw/Makefile: Include epscairo terminal. 2011-10-01 Christoph Bersch <cbersch@users.sourceforge.net> * term/post.trm term/pslatex.trm: New options `background` and `nobackground` for terminals postscript, epslatex, pstex and pslatex. Patch #3415158 2011-09-29 Ethan A Merritt <merritt@u.washington.edu> * src/color.c src/graph3d.c src/graphics.c: User-specified axis tick labels should override auto-generated tick labels in 3D plots just as they already do in 2D plots. * src/plot2d.c: In `plot with labels`, skip labels for which the x,y coordinates are UNDEFINED. Bug #3415454 * term/js/gnuplot_mouse.css: Opera is picky about missing units. 2011-09-27 Ethan A Merritt <merritt@u.washington.edu> * term/emf.trm term/fig.trm term/metapost.trm term/tgif.trm: Prefer the new syntax set term ... font "<name>,<size>" in the documentation. This does not change the terminal input, only the docs and the options string echoed back by "show term". * term/canvas.trm: Implement set term canvas ... font "<name>,<size>". Currently the name is ignored. 2011-09-23 Ethan A Merritt <merritt@u.washington.edu> * docs/gnuplot.doc src/plot2d.c: Defer interpretation of newhistogram linetype until the histogram itself is drawn. 2011-09-21 Bastian Maerkisch <bmaerkisch@web.de> * demo/borders.dem: Use loop instead of `reread`. * demo/image2.dem: Explicitely `reverse` axes. * src/win/wgraph.c (drawhraph) [W_filled_polygon_draw]: Transparent pattern fill actually fills with white background since 2011-05-15. Fixed. * src/win/wgnuplib.h src/win/wgraph.c (WndGraphProc) term/win.trm (WIN_options, WIN_update_options): Update term options on changes via graph window/menu. Track font face and size as read from ini-file. * src/stdfn.c|h (gp_basename) term/pslatex.trm (PSTEX_common_init): Move code from pslatex.trm to new function gp_basename which takes two different directory separators into account and does not change its argument. 2011-09-16 Peter Hedwig <peter@affenbande.org> * term/lua/gnuplot-tikz.lua: Modify the commands used for rgb color selection so that they are compatible with context as well as tikz. Bug #3401068 2011-09-16 Oliver Jennrich * term/lua/gnuplot-tikz.lua: Update syntax used for setting line join properties. Bug #3410554 2011-09-12 Bastian Maerkisch <bmaerkisch@web.de> * config/mingw/Makefile: Fix building gnuplot.ps and gnuplot.pdf. Include figures in gnuplot.pdf. Define new targets 'console', 'windows' and 'pipes' to build different versions of gnuplot. Use separate file extensions for each version. Let 'make all' build all versions. Match 'install' target to Tatsuro Matsuoka's packages. 2011-09-09 Ethan A Merritt <merritt@u.washington.edu> * docs/doc2tex.c docs/titlepag.tex: Tweak format of TeX documentation (no section numbers in table of contents, text width appropriate for paper size). 2011-09-09 Bastian Maerkisch <bmaerkisch@web.de> src/win/wgnuplib.h src/win/wgraph.c src/win/wresourc.h term/win.trm: Add a toolbar to the graph window. Currently, it offers icons for Copy, Print, Save and Options. Additionaly, plot elements can be temporarily hidden, ie. without a `replot`. This is much like what can be done using canvas and svg terminals and is implemented using term->layer. 2011-09-08 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (plot_image_or_update_axes): "with image" from a function may not make sense, but at least it should not segfault.

The mgr window system offered a terminal sort of like xterm+graphics in the era of Sun3 (i.e. early-mid 1990s). Source for the mgr server has apparently disappeared from the net. Gnuplot's mgr.trm supported only text and vector commands, so even if an operational installation of mgr could be found, features added to gnuplot since about version 3.7 would be irrelevant. Let it go. 2011-08-27 Peter Juhasz <juhaszp@users.sourceforge.net> * src/datafile.c (expect_string) src/eval.c src/eval.h docs/gnuplot.doc: Add patch #3397007 to complete the support for named columns with the "labels" style. The following now works: plot 'data' using "A":"B":"labels" with labels Update the documentation. * src/datafile.c (f_timecolumn) src/plot2d.c: Track the current using spec to ensure that the timecolumn function gets the right timeformat. (fixes part of bug #3163386) * demo/timedat.dem: Remove the relative date demo because it was misleading and incorrect. * src/set.c (set_tics): For some options set_tics() didn't act on all axes. * src/graphics.c (boundary): Fix (?) boundary calculation for "set xtics rotate". 2011-08-25 René Haber <renehaber@users.sourceforge.net> * term/cairo.trm: New terminal epscairo using the shared cairo/pango code to produce and export an eps surface. * term/term.c: Allow "set term eps" as short for "set term epscairo". 2011-08-24 Bastian Maerkisch <bmaerkisch@web.de> * src/command.c src/command.h src/win/winmain.c: "raise/lower <id>" command for windows terminal. * src/command.c (rlgets): Restore code for builtin readline which was deleted by accident. 2011-08-23 Peter Juhasz <juhaszp@users.sourceforge.net> * src/datafile.c (f_stringcolumn) docs/gnuplot.doc: Implement 'stringcolumn("string")' in using specs to allow named columns for the "labels" style too. The more natural plot 'data' using "A":"B":"labels" with labels still doesn't work: document this fact. 2011-08-23 Bastian Maerkisch <bmaerkisch@web.de> * src/command.c (rlgets): Removing duplicate entries trashes command line history when using editline. Just suppress adding the same command to history repeatedly. * src/history.c (history_find_all): editline's version of history_set_pos() does not work, so traverse history list manually. History indices are reversed compared to GNU readline. Fixes history ?. Patch #3186010 * term/emf.trm (EMF_put_text): Use iconv (if available) to convert UTF-8 encoding to UTF-16 and store using wide characters. Bug #3021779 * config/config.mgw config/mingw/Makefile: add support for libiconv 2011-08-22 Ethan A Merritt <merritt@u.washington.edu> * src/graph3d.c: Honor 'set key maxrows N' in 3D plot key. Bug #3396501 2011-08-19 Ethan A Merritt <merritt@u.washington.edu> * src/commands.c src/misc.c docs/gnuplot.doc: The old-style if/else syntax cannot be mixed with the new syntax using { and } to enclose blocks of commands, possibly spanning several lines. Add stronger warnings to the documentation and issue an error message if an old-style if statement is encountered inside a bracketed clause. Bug #3393631 2011-08-15 Bastian Maerkisch <bmaerkisch@web.de> * src/win/wgraph.c (WndGraphProc): Restore text window on space key: also show terminal window if it is currently minimized. * src/command.c (pause_command) src/win/wgnuplib.h (GW) src/win/wgraph.c src/win/winmain.h src/win/winmain.c term/win.trm: Support multiple graph windows. All state variables of graph windows were contained in a single struct already. Replace all references to this struct (graphwin) by pointers and dynamically allocate new instances when required. Do not pass on mouse and key events from inactive windows. Note: Since a single number passed to `set term win` is now interpreted as window identifier, the old and fontsize options are no longer supported and the `font` keyword is now required. This is consistent with other terminals (e.g. x11 and wxt). * src/win/wgnuplib.h src/win/wgraph.c: Make GraphChangeFont static. 2011-08-15 Reinier Heeres <rheeres@users.sourceforge.net> * src/win/pgnuplot.c: Detect termination of wgnuplot.

Use cached color brush for transparent solid fills instead of creating a new one. * src/win/wgraph.c (drawgraph) src/win/wgdiplus.c|h: Add support for antialiased solid filled (transparent) polygons. * src/win/wpause.c (WndPauseProc): Use default dialog font instead of fixed width font for pause dialog. * src/readline.c (readline): Tab is a printable character in some locales, ie. isprint(TAB)>0. * src/win/wgraph.c (MakeFonts): Reduce size of tics and point symbols by 20%. 2011-05-04 Bastian Maerkisch <bmaerkisch@web.de> * config/mingw/Makefile: Build support for lua tikz related TeX files. Use Makefile.maint to update version.c. Update install target to match directory layout of distribution and include share/lua/, share/LaTeX/, contrib/, demo/, README, NEWS, Copyright and ChangeLog. 2011-05-02 Ethan A Merritt <merritt@u.washington.edu> * src/variable.c (locale_handler): If built-in readline character input is to recognize UTF-8 characters via wcwidth(), it is necessary to initialize the CTYPE locale on entry. "set encoding utf" is not sufficient. 2011-05-02 Bastian Maerkisch <bmaerkisch@web.de> * src/readline.c (tab_completion, fn_completion, readline) NEWS: Cycling variant of filename tab-completion for builtin readline. * src/stdfn.c|h (strnlen, strndup) configure.in config/config.nt config/config.mgw config/config.oww: Support functions used by tab-completion code. * src/stdfn.c|h (opendir, closedir, rewinddir): Add Kevlin Henney's POSIX directory browsing functions and types for Win32. * src/readline.c (mbwidth, isdoublewidth) configure.in: Determine on screen width of utf8 encoded characters with wcwidth() if provided by the system. * src/readline.c (delete_previous_word): Overprint with exact number of spaces, add NUL at eol. 2011-04-30 Ethan A Merritt <merritt@u.washington.edu> * src/readline.c (clear_eoline): More efficient clear line algorithm. 2011-04-29 Ethan A Merritt <merritt@u.washington.edu> * src/mouse.c (apply_zoom): Prevent double-free of custom font for tic labels. Bug #3294915 2011-04-28 Bastian Maerkisch <bmaerkisch@web.de> Support for (optional) antialiasing in windows terminal via GDI+. * config/config.mgw, config/config.nt: Compilers have support for GDI+: define HAVE_GDIPLUS. Note: OpenWatcom might not support GDI+ * config/mingw/Makefile: Include new files wgdiplus.h|cpp in build, add library gdiplus. * src/win/wgdiplus.cpp src/win/wgdiplus.h: New files. C interface to Windows GDI+ library. Currently supports polylines and circles. * src/win/wgnuplib.h src/win/wgraph.c src/win/winmain.c src/win/wresourc.h: Implement antialiasing for lines and and most point shapes. Add option to LPGW, wgnuplot.ini and popup menu to toggle antialiasing on and off. Default to oversampling off now that we have proper antialiasing. Wrap all GDI+ code in #ifdef HAVE_GDIPLUS. * src/win/wgraph.c (drawgraph) [W_fillstyle, FS_PATTERN]: Fix cycling of pattern styles. * src/wxterminal/gp_cairo.c|h (gp_cairo_default_font) src/wxterminal/wxt_gui.c: New function to determine default font. Default is "Sans" on all systems but Windows where this alias might not work work in all cases. 2011-04-27 <wtf3@users.sourceforge.net> * src/graphics.c: The autotitle option for column-stacked histograms should honor "set key maxrows N". Bug #3281635 2011-04-27 Bastian Maerkisch <bmaerkisch@web.de> * src/command.c (help_command) src/win/winmain.h src/win/winmain.c (WinExit, ShutDown, WinCloseHelp, WinMain): Work-around for apparently well known html help bug, which causes spurious crashes on exit. Keep track of help window handle and try to close the window as soon as possible. New function WinCloseHelp. Extensive update to color, linetype and fillstyle handling in windows terminal. Fixes several bugs and implements new options. * term/win.trm (WIN_id, WIN_opts, WIN_options): Add options "solid", "dashed", "background", "fontscale" and "linewidth". Call new function GraphInitStruct to initialize graphwin. Inlcude font in term_options. * term/win.trm (WIN_point, WIN_filled_polygon): Handle dashed lines in drawgraph, not here. (WIN_filled_polygon): Use generalized W_fillstyle call, shared with WIN_boxfill. (WIN_boxfill): Pass second corner as parameter, not width and height. Fixes spurious rounding errors during translation to graph coordinates. (help text): Document new options. * src/win/wgnuplib.h (GW): Reorder entries according to function. * src/win/wgraph.c (pattern_bitmaps): Fix double cross-hatch. (GraphInitStruct): New function. (MakePens, DestroyPens): Account for linewidth and sampling and create an additional "null" pen which is used for filled polygons and boxes. (MakeFonts, GraphEnhancedOpen) Account for fontscale. (draw_new_pens, draw_new_brush) New functions to (re)create brushes and pens. Always create a "solid" partner for the possibly "dashed" pen. Called by drawgraph. * src/win/wgraph.c (drawgraph): Reorder variables according to function. [W_line_type]: Save last LOGPEN instead of pen index. Make use of draw_new_pens. Select background brush for line-type <= LT_NODRAW (fix by Shigeharu Takeno, Bug 3192205). [W_fillstyle]: Unify code for filled boxes and polygons. Use draw_new_brush. [W_boxfill]: Fillstyle is now set by previous call to W_fillstyle. Change interface from relative (width, height) to absolute position to avoid off by one rounding errors. Deselect brush use for transparent fill before deleting it. [W_line_width] Scale by linewidth option. [W_setcolor] Use save LPOGEN to create pens with new color. Use draw_new_brush and draw_new_pens to recreate brushes and pens. [W_filled_polygon_draw] Fillstyle is now set by previous call to W_fillstyle. Use "null" pen to avoid drawing a border around filled area. [W_image] Avoid static variables. [W_plus,...] Use solid pen. Fixes point symbols drawn with dashed lines. Adresses Bug 1952364. 2011-04-26 Ethan A Merritt <merritt@u.washington.edu> * src/readline.c: Revise the built-in readline code to handle UTF-8 encoded character input. The revised code is only active if the user has explicitly done "set encoding utf8" or "set encoding locale", but probably it should be the default in a UTF-8 locale. * src/readline.c (clear_line): More efficient clear line algorithm. 2011-04-25 Ethan A Merritt <merritt@u.washington.edu> * src/plot.c (main) src/misc.c (load_file): Initializing c_token to an illegal value is not a good idea. Bug #3292512 2011-04-23 Shigeharu Takeno <shige@iee.niit.ac.jp> * docs/gnuplot-ja.doc docs/term-ja.diff: sync to docs version 1.664. * docs/Makefile.in (wxhelp/doc2html.o): Add missing space. 2011-04-22 Ethan A Merritt <merritt@u.washington.edu> * src/readline.c docs/gnuplot.doc: Built-in readline did not recognize the character sequence produced by the DEL key on many keyboards. Trap this sequence for interpretation as "forward delete", which is what the same key does under windows and gnu libreadline. This does not affect keyboards or xmodmap configurations where the DEL key produces another sequence entirely. 2011-04-22 Bastian Maerkisch <bmaerkisch@web.de> * src/readline.c: The behavior of ^W was not consistent with the documentation. Change it to match gnu libreadline (delete previous partial or full word). 2011-04-20 Ethan A Merritt <merritt@u.washington.edu> * src/gplt_x11.c: Most of the messages passed via the title bar of the X Display window are controlled by #ifdef TITLE_BAR_DRAWING_MSG. Do the same for the "allocating colors..." message. 2011-04-19 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> * config/Makefile.am.in (Makefile.am): Additional files to become part of the distributed tarball. Reindented. 2011-04-19 Ethan A Merritt <merritt@u.washington.edu> * src/datafile.c (f_columnhead df_set_key_title) src/datafile.h src/eval.c src/plot2d.c (eval_plots) docs/gnuplot.doc: New function columnhead(N) that returns a string containing column N from the first line of a data set. 'plot ... title columnhead(i)' was previously implemented as a keyword; making it a function instead allows, for example, 'plot for [i=3:6] ... title "Results of ".columnhead(i)' 2011-04-19 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> * docs/Makefile.in (wxhelp/doc2html, gnuplot.htb): Ooops. Yesterday's directory name change to windows was wrong. Undoing it. 2011-04-18 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> * term/Makefile.am.in: Use $< where applicable. ($(srcdir)/lua/gnuplot-tikz.help): Make workable outside the source tree. Use $< and $@ where applicable. * docs/Makefile.in (CLEANFILES): Fix broken directory name; indent. (gnuplot.htb): Fix broken directory name. Make workable in out-of-source builds. (windows/wgnuplot.html, windows/doc2html.o, windows/doc2html): Fix wrong directory name. * Makefile.maint (amfiles): Missing semicolon. 2011-04-18 Bastian Maerkisch <bmaerkisch@web.de> * src/win/wgraph.c (drawgraph): Fractional solid fill based on SF Patch 2905570 by Shigeharu Takeno. Remove halftone brushes. Eliminate static variable to keep track of pm3d brushes. 2011-04-17 Bastian Maerkisch <bmaerkisch@web.de> * config/mingw/Makefile: Use $^ and $< where applicable. Patch by Benjamin Lindner, SF Patch 2468650. Set TARGET only if it's not already defined. GNUPLOT_LUA_DIR was included twice in TERMOPTIONS. GNUPLOT_PS_DIR is required by show.c. [wgnuplot.chm] Avoid changing directory via shell which seem not to work reliably on all systems. 2011-04-17 Ethan A Merritt <merritt@u.washington.edu> * config/Makefile.am.in: Fix package-build breakage. 2011-04-17 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> Building the three different types of executable for Windows was quite cumbersome (change make variable, make clean, build, all that thrice). Compiling to three different object file name extensions helps with that. * config/watcom/Makefile (VARIANT): New macro to choose among targets. (TARGETS_PLAIN, EXTRA_CPPFLAGS_PLAIN, TARGETS_PIPES) (EXTRA_CPPFLAGS_PIPES, TARGETS_CONSOLE, EXTRA_CPPFLAGS_CONSOLE): New macros for settings particular to one variant. (DEFAULT_TARGETS): Changed definition to use new per-variant macros. (ALL_TARGETS): New macro listing all things that can be built. (all): New target building all variants without the need to make clean in between. (WIN_EXTRA_INPUTS): Removed $(WINOBJS) (OBJS): Add $(WINOBJS) here instead. (CONSOLE_OBJS, PIPE_OBJS): Copies of $(OBJS) with different object filename extension. Use $(O) in favour of fixed .obj, to allow renaming trick. (.EXTENSIONS): Add .cobj and .pobj to list of recognized file name extensions. (.c.cobj): New implicit rule to compile sources for the console build. (.c.pobj): New implicit rule for pipe-enabled build. (wgnuplot.exe): $(WINOBJS) is contained in $(OBJS) now. (wgnuplot_pipes.exe): Use $(PIPE_OBJS) instead of $(OBJS) (gnuplot.exe): USE $(CONSOLE_OBJS) instead of $(OBJS) (term.cobj): New explicit rule to compile term.c for the console build. (term.pobj): New explicit rule to compile term.c for the pipe build. (.c): Added windows source subdirectory to VPATH search list. (w*.obj): Removed unnecessary explicit rules for Windows-specific files. (clean): Remove object files with new names. * config/watcom/.cvsignore: Add new file name extensions to ignore. 2011-04-17 Bastian Maerkisch <bmaerkisch@web.de> * config/makefile.cyg config/makefile.mgw config/makefile.unx cygwin/Makefile mingw/Makefile: Remove dependencies on wgnuplot.def and wgnuplib.def. * src/wgnuplib.def: Removed 2011-04-16 Bastian Maerkisch <bmaerkisch@web.de> * config/config.amg config/makefile.msc config/term.pc.h config/makefile.win config/makefile.ztc src/win/wgnuplot.def src/win/wgnupl32.def: Remove build files for no longer supported platforms DOS16, WIN16, Amiga and compilers. * src/ansicheck.h src/command.c src/eval.h src/stdfn.h src/syscfg.h src/term.c src/term.h src/makefile.all src/makefile.awc docs/Makefile.in term/fg.trm : Remove suport for the Zortech compiler and the no longer available Flash Graphics library. 2011-04-15 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (plot_steps) src/gp_types.h src/graph3d.c src/tables.c docs/gnuplot.doc docs/plotstyles.gnu: New plot style "with fillsteps" is identical to "with steps" except that the area between the stepped line and the baseline at y=0 is filled using the currently active fill style. * src/graphics.c (plot_fsteps, histeps_vertical) (histeps_horizontal): Simplify the code to use clip_line() rather than lots of in-line tests. * term/dumb.trm docs/gnuplot.doc: Updates 2011-04-15 Bastian Maerkisch <bmaerkisch@web.de> * src/readline.c (msdos_getch, readline), src/win/winmain.c (ConsoleGetch): Don't quit on DEL on an empty line. Map DEL key to del character 127 instead of ^D, but keep old behaviour of deleting current character on platforms Windows, MSDOS and OS/2. SF Bug #3285571 2011-04-13 Peter Hedwig <peter@affenbande.org> * term/lua/gnuplot-tikz.lua: Fix "charsize" option. 2011-04-13 Ethan A Merritt <merritt@u.washington.edu> * term/canvas.trm term/gd.trm term/svg.trm term/x11.trm src/misc.c: Stricter checks that the red component of RGB colors stays in range. 2011-04-13 Bastian Maerkisch <bmaerkisch@web.de> * src/win/wgraph.c (WndGraphProc), src/win/wtext.c (WndTextProc): Enable access to popup menu via status bar and keyboard. 2011-04-12 Bastian Maerkisch <bmaerkisch@web.de> * src/win/wtext.c (WndParentProc) [WM_SIZE]: Ignore requests to set window size to 0,0. Fixes crash on Vista if Windows-D is pressed. 2011-04-11 Ethan A Merritt <merritt@u.washington.edu> * term/js/gnuplot_common.js: Fix the clipping of filled rectangles when zoomed. 2011-04-11 Petr Mikulik <mikulik@physics.muni.cz> * src/config/mingw/Makefile: Fixed relative directories in RCFLAGS. 2011-04-10 Bastian Maerkisch <bmaerkisch@web.de> * src/term/win.trm, src/win/wgraph.c, src/win/wgnuplib.h: Renew text handling: Process enhanced text in drawgraph(), new functions GraphEnhancedOpen(), GraphEnhancedFlush(), revised GraphGetTextLength(). This most notably fixes behaviour when resizing the graph window. Collect static variables used for the internal state of enhanced text processing into a struct. Move code out of main loop of drawgraph: New functions draw_put_text(), draw_text_justify(), draw_enhanced_text(). Fix baseline alignment of normal and enhanced text. Text position was moving in wrong direction for rotated enhanced text (fix replaces change dated 2011-02-11). Remove unused function GraphGetFontScaling(). Fix text positioning of enhanced text with oversampling. * term/win.trm (WIN_graphics): Update character and window size. * src/win/wgraph.c (WndGraphProc): Remove another Win16 relict. * term/win.trm, src/win/wgnuplib.h, src/win/wgraph.c: Remove LPGW.resized, rename commands no longer exclusively used for pm3d. * src/win/wgraph.c (UnicodeText): Add codepage 1250. * term/win.trm (WIN_Init), src/win/wgraph.c (GraphInit): Move loading of icon. * term/win.trm (WIN_scale): Removed. * term/win.trm (WIN_options), src/win/winmain.c (WinMain): Eliminate need for static variable WIN_gtitle. * term/win.trm (WIN_set_pointsize), src/win/wgraph.c (drawgraph) [W_pointsize]: Don't pass size as string. * src/win/wgraph.c (drawgraph) [W_line_type]: Only init LOGBRUSH lb if it is used. * term/win.trm, src/win/wgraph.c: Various small code cleanups. 2011-04-09 Ethan A Merritt <merritt@u.washington.edu> * term/svg.trm term/js/gnuplot_svg.js: Draw all grid lines with attribute class="gridline". Add an icon to toggle on/off lines with this attribute. Move both this icon and the mouse coordinate tracking box to the end of the output *.svg file so that they cannot be occluded by plot elements. * term/svg.trm (SVG_PathClose): Firefox 3.x fails to render purely vertical lines. This is particularly noticeable because all vertical grid lines are missing. Work around this by adding 0.01 to the final x coordinate. 2011-04-08 Ethan A Merritt <merritt@u.washington.edu> * term/svg.trm: Adjust enhanced text placement, removing some kludges that appear not to be necessary with the current generation of browsers. * term/svg.trm term/js/gnuplot_svg.js: Implement mouse tracking framework. 2011-04-07 Ethan A Merritt <merritt@u.washington.edu> * src/term.h term/svg.trm demo/html/webify_svg.pl demo/html/Makefile.svg demo/html/Makefile.svg: Add bitmap image handling to the svg terminal using the same mechanism of external png files used by the canvas and tikz terminals. * term/svg.trm(SVG_init): Konqueror (KDE 4.5) crashes if the xlink to gnuplot_svg.js fails to load. Work around this by adding a test for the presence of gnuplot_svg before initializing. 2011-04-06 Bastian Maerkisch <bmaerkisch@web.de> * term/win.trm, src/win/wgnuplib.h, src/win/wgraph.c: Use UINTs instead of DWORDs in struct GWOP. * src/win/wgraph.c, src/win/wgnuplib.h: Move static flag for unsupported encodings to struct LPGW. This ensures that errors are reported only once. 2011-04-06 Ethan A Merritt <merritt@u.washington.edu> * src/graph3d.c src/graphics.c src/term_api.h: Add layering flags for BEGIN/END KEYSAMPLE. * term/js/gnuplot_svg.js term/svg.trm: Elementary mousing support for the svg terminal based on Patches #2477391 #2478169 (yeah, those are from 2 years ago). Toggle plot on/off in response to mouse click on the corresponding key entry. * demo/html/Makefile.svg demo/html/index.svg demo/html/webify_svg.pl: Revise the svg demo set to use mousing. * src/graphics.c (do_plot) src/term_api.h (TERM_LAYER_RESET_PLOTNO) term/svg.trm term/canvas.trm: The "set key opaque" option was causing mismatched begin/end plot pairs in output from the svg and canvas terminals (begin/begin/end). Revise this so that the plot and the key sample numbering is out of sync. 2011-04-05 Ethan A Merritt <merritt@u.washington.edu> * src/color.c (ifilled_quadrangle): See note in the code. For some reason this fixes rendering of pm3d surfaces in the svg terminal. 2011-04-04 Ethan A Merritt <merritt@u.washington.edu> * term/canvas.trm demo/html/mousebox.template term/js/gnuplot_mouse.js: Incorporate the plot name (from 'set term canvas name "foo") into the flag used by the toggleVisibility() routine so that plots in other canvas elements on the same page are not affected. 2011-04-03 Ethan A Merritt <merritt@u.washington.edu> * src/term.c src/term.h term/Makefile.am.in term/lua.trm term/write_png_image.c: Move the routine write_png_image() out of lua.trm so that it can be shared by other terminal drivers. It requires support from either libgd or cairo, and provides bitmapped image support to the lua terminals and (in prospect) to the HTML5 canvas terminal. * src/save.c: Echo most recent range of autoscaled axes on "show" but not "save". This simplifies the output of gpsavediff in most cases. * gnuplot-cvs/term/js/gnuplot_mouse.js term/js/gnuplot_common.js gnuplot-cvs/term/canvas.trm (CANVAS_image): Implement support for image handling in the canvas terminal using the HTML5 canvas primitive drawImage(). Image data is written to a png file in parallel to generation of the main plot. The png image can then be loaded from the javascript handler for the plot it belongs to. * demo/html/Makefile demo/html/Makefile.canvas demo/html/index.canvas demo/html/mousebox.template: Update the demo collection to show the new image handling. 2011-04-01 Ethan A Merritt <merritt@u.washington.edu> * term/canvas.trm demo/html/webify_canvas.pl: Add HTML5-conformant doctype and meta-information to output html. * src/graph3d.c: Wrap pm3d surfaces and hidden3d ensembles in BEFORE_PLOT/AFTER_PLOT flags via term->layer(). This allows them to be toggled on/off like other plots in HTML canvas output. * src/term.c(null_layer) src/graphics.c src/graph3d.c: Provide a null_layer() routine for all terminals that do not provide term->layer(). This allows us to remove explicit checks for support by the current terminal. 2011-03-30 Ethan A Merritt <merritt@u.washington.edu> * demo/html/index.canvas demo/html/Makefile.canvas demo/html/mousebox.template demo/html/webify_canvas.pl: Separate make targets for 2D and 3D plots. Add buttons for toggling individual plots. Default to mousing enabled for all demo plots. * term/canvas.trm: Wrap each component plot in a test for (gnuplot.hide_plot_N). Add plot-toggling buttons to the standalone mousebox. Report gnuplot version in each plot generated. * term/gnuplot_common.js term/gnuplot_mouse.css term/js/canvas_help.html term/gnuplot_mouse.js (popup_help(URL) toggle_plot(N)): Add version number to shared javascript code modules. Add support for linking help button to plot-specific URL. Add support for toggling individual component plots on/off. 2011-03-30 Bastian Maerkisch <bmaerkisch@web.de> * term/gd.trm: Don't try to reuse names of gd font pointers for local variables. Fixes build with MinGW and DLL version of libgd. * config/mingw/Makefile: Optionally, use pre-built DLL version of libgd. Use environment variable PROGRAMFILES to access help compilers. 2011-03-29 Bastian Maerkisch <bmaerkisch@web.de> * src/win/wgnuplib.rc, src/win/wgnuplot.rc, src/win/wresourc.h: Use standard dialog font. Remove obsolete DS_3DLOOK. * src/win/winmain.c (WinMain): Sync About Dialog box with output of "show version". * src/win/wmenu.c (SendMacro), src/win/wgnuplot.mnu: Add About dialog to Help menu. * src/win/wmenu.c (SendMacro), src/win/wgnuplot.mnu: Add Options menu to toolbar. 2011-03-28 Ethan A Merritt <merritt@u.washington.edu> * src/plot2d.c (get_data): Fix array bounds underflow if every point in a data file is invalid. Bug #3254653 2011-03-28 Bastian Maerkisch <bmaerkisch@web.de> * src/win/wtext.c: Always update complete lines of text instead of drawing single characters, since character boxes might overlap when using ClearType. * docs/README: Document recent changes to Windows help. * src/win/wgnuplib.h, src/win/wcommonh.h, src/win/wtext.c: Continue to make more stuff module-local. * src/win/wgnuplib.h, src/win/wmenu.c: Move definition of SHELL_DIR_DIALOG. * config/config.nt: Sync with config.h created by autoconf. 2011-03-26 Shigeharu Takeno <shige@iee.niit.ac.jp> * term/gd.trm (PNG_put_text ENHGD_FLUSH gd_iconv): Invoke the SJIS/UTF8 conversion for both enhanced and non-enhanced text. EAM - and collapse the shared code into a subroutine. 2011-03-26 Bastian Maerkisch <bmaerkisch@web.de> * config/mingw/Makefile: Add missing paths to wxt/cairo/pango files. Update build instructions. WX_LOCATION is no longer required since gnuplot has its own manifest file now and the one supplied by wxWidgets is no longer included. htmlhelp.lib is included in LDLIBS not TERMFLAGS. Replace '=' by ':=' for shell commands. Filter out drive specifications "c:" in results from pkg-config which would confuse make. 2011-03-25 Ethan A Merritt <merritt@u.washington.edu> * src/pm3d.c docs/gnuplot.doc: Allow pm3d plots to use the fourth column of data as "rgb variable" rather than "palette z". 2011-03-25 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> * src/win/wtext.c: Make more stuff module-local. Resolve several signedness conflicts introduced by functions in new screenbuf.c module. 2011-03-25 Bastian Maerkisch <bmaerkisch@web.de> * src/plot.c (main), src/win/winmain.c (WinMain, WinExit), src/win/wcommon.h: The code which changes the codepages for console gnuplot is only compiled in if CONSOLE_SWITCH_CP is defined. Otherwise gnuplot will only display a warning if codepages differ. Handle the case when codepages already match. 2011-03-24 Ethan A Merritt <merritt@u.washington.edu> * src/Makefile.maint: Fill in the "last modified" date from the most recent entry in the ChangeLog rather than the using the current date, and only then if the VERSION or PATCHLEVEL has been changed. Caution: tested only under linux with gnu make. 2011-03-22 Bastian Maerkisch <bmaerkisch@web.de> * src/graphics.c (do_plot, plot_points): Test wether the terminal actually supports set_color. Fixes crashes with terminal dumb. 2011-03-21 Bastian Maerkisch <bmaerkisch@web.de> * src/win/wgraph.c (WIN_image): Fix regression: rotation of images with reversed axis was not working since rev. 1.92. 2011-03-20 Ethan A Merritt <merritt@u.washington.edu> * src/util.c (equals): Test here for token index in range, rather than trusting all callers to get it right. * src/command.c src/parse.c: Token index range test is now redundant. * docs/gnuplot.doc: Document that ^D from an empty line acts as EOF. 2011-03-20 Bastian Maerkisch <bmaerkisch@web.de> * src/win/wgnuplib.c|h, src/win/wgraph.c, src/win/winmain.c, src/win/wmenu.c, src/win/wpause.c, src/win/wtext.c: FAR pointers are no longer required. * src/win/winmain.c (WinExit): Explicitly close help window on exit.

Bug #3165902 2011-01-25 Ethan A Merritt <merritt@u.washington.edu> * src/set.c (set_encoding): Check result of "set encoding locale" to see if we have just loaded an sjis (codepage 932) locale. 2011-01-25 Shigeharu Takeno <shige@iee.niit.ac.jp> * src/term.c src/term_api.h term/post.trm term/svg.trm NEWS docs/gnuplot.doc: "set encoding sjis" allows characters in Shift-JIS Japanese encoding to survive enhanced text processing by the postscript and svg terminals. 2011-01-23 Ethan A Merritt <merritt@u.washington.edu> * src/graph3d.c (xtick_callback ytick_callback ztick_callbacke): Revert change made 2011-01-20 because it breaks hidden3d. * src/util3d.c (map3d_xy_double): Instead revise the map3d_xy() code path to share the coordinate transformation used by map3d_xyz(). Bug #3157712 2011-01-22 Shigeharu Takeno <shige@iee.niit.ac.jp> * src/win/wgraph.c: Fix typo in previous definition of _WIN32_WINNT. 2011-01-21 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (plot_boxplot): Handle some corner cases (all points have the same value, fewer than 4 valid points). Bug #3162872 2011-01-20 Ethan A Merritt <merritt@u.washington.edu> * src/graph3d.c (xtick_callback ytick_callback ztick_callbacke): Gnuplot uses two different pathways to convert 3D coordinates in user space into 2D coordinates in the terminal coordinate space. One of these goes via map3d_xyz() and TERMCOORD(); the other uses map3d_xy(). Unfortunately it seems the two paths can differ by +/- one pixel in the final terminal coordinates. This discrepancy is particularly noticeable in the grid and axis tic placement of 3D plots after "set view map" (Bug #3157712). This patch switches the tick_callback() routines to use the map3d_xy() pathway, which fixes the problem case described by the bug report. It would be to make both pathways share the same underlying code so that the discrepancy doesn't occur in other conditions. Bug #3157712 2011-01-19 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (place_raxis): If the polar axis maximum is autoscaled, draw the raxis all the way to that maximum value.

(There are still some svga users after all!) * term/emf.trm: Use the EMR_ELLIPSE primitive to draw point types 6 and 7. Make point types 4 and 5 slightly larger (looks better on MSWin). Switch to using linecap=flat and linejoin=miter by default, but add option "rounded/butt" to toggle this. 2010-11-29 Ethan A Merritt <merritt@u.washington.edu> * src/set.c (set_decimalsign): Possible fix for problem with numeric locales on Windows. Bug #3120819. 2010-11-28 Ethan A Merritt <merritt@u.washington.edu> * src/gadgets.c src/gadgets.h src/graphics.c demo/dashcolor.dem: Fix breakage to the pointinterval property that was caused by opaque key support. Add a demo plot illustrating pointinterval. 2010-11-26 Ethan A Merritt <merritt@u.washington.edu> * term/canvas.trm demo/html/webify_canvas.pl term/js/gnuplot_common.js term/js/gnuplot_dashedlines.js: Add support for dashed lines and rounded/butt line properties. 2010-11-24 Ethan A Merritt <merritt@u.washington.edu> * term/canvas.trm term/js/gnuplot_common.js term/js/gnuplot_mouse.js: Revamp the javascript support for the HTML5 canvas terminal. Move all global variables into a single object "gnuplot" declared in gnuplot_common.js. This revision also adds polar mode mousing support. * demo/html/Makefile.canvas demo/html/index.canvas demo/html/mouseable.dem demo/html/mousebox.template demo/html/webify_canvas.pl: Revamp the demos and build scripts to use the new javascript syntax. See tracker item #3058147 2010-11-23 Ethan A Merritt <merritt@u.washington.edu> * term/js/gnuplot_common.js: Rotated text should be zoom-able also. * term/js/gnuplot_mouse.js: Konqueror (webkit?) implementation of ctx does not like negative values of width or height. * src/eval.c (fill_gpval_axis) term/canvas.trm: Export polar axis limits and logscale status for external mousing. 2010-11-20 Casey Carter <ctcarter@users.sourceforge.net> * demo/html/index.canvas demo/html/index.save demo/html/index.svg term/canvas.trm: syntax error in link record of standalone mode. 2010-11-18 Ethan A Merritt <merritt@u.washington.edu> * src/axis.c src/axis.h src/command.c src/eval.c src/graphics.c src/misc.c src/mouse.c src/plot2d.c src/save.c src/set.c src/setshow.h src/show.c src/tables.c src/tables.h src/unset.c demo/polar.dem demo/poldat.dem docs/gnuplot.doc: Improved support for polar coordinate mode. The polar axis gets syntax and properties equivalent to the x/y/z axes. - set/unset raxis (always drawn through the origin) - set rrange controls the extent of the axes and of the plot itself; the xrange and yrange are set to match, but can be changed afterward - set rtics (drawn to right of origin; optionally mirrored to the left) - set log r (does not affect scaling on x or y) - polar coordinate readout from mousing - filledcurves bounded by constant r - polar.dem (turn off rtics so the demo output remains as before) poldat.dem (add a plot showing raxis, rtics, and log scaling on r) * src/set.c (set_grid): Clean up the option parsing for set grid. * src/save.c: save output for "set view" could not be read in. 2010-11-16 Ethan A Merritt <merritt@u.washington.edu> * src/gadgets.c (clip_line): When draw_clip_line() was made into a wrapper for clip_line() in May 2000, they differed in a single test. The version of the test from clip_line() was kept. But this broke the case clip_line(x, ymin, x, ymax+eps), which clipped to ymin,ymin rather than to ymin,ymax. I do not know if there were any callers of clip_line() at the time that needed the variant test, but if so they no longer exist. There is now only one other caller of clip_line(). Restore the test to the version that is correct for draw_clip_line(). * src/graphics.c (place_grid xtick2d_callback plot_impulses) src/term.c (do_arrow): Simplify these routines to use draw_clip_line(). 2010-11-13 Ethan A Merritt <merritt@u.washington.edu> * configure.in INSTALL src/Makefile.am src/term.c src/term.h: The copyright notice in bitmap.c is more restrictive than the gnuplot license. The new configuration option --without-bitmap-terminals omits this code from the gnuplot executable and also disables all terminals that depend on it. These are: epson.trm hp500c.trm hpljii.trm hppj.trm pbm.trm This affects HP deskjet-era printers, but not HPGL or PCL5 printers. * src/set.c: Replace unnecessary memcpy() calls with direct assignment. * docs/Makefile.in: Add gnuplot.pdf to the distributed package. Install it in the same directory as gnuplot.gih. 2010-11-12 Ethan A Merritt <merritt@u.washington.edu> * docs/gnuplot.doc command.c (help_command) util.h: "help" was collapsing all text to lower case, which broke "help 3D". Remove a vestigial call to lower_case(). Also make sure it is indexed. 2010-11-07 Ethan A Merritt <merritt@u.washington.edu> * src/axis.c src/axis.h src/set.c src/unset.c: Re-arrange the order of axes in the axis_table[] array so that all the parametric axes are at the end. This makes it easy to iterate over only those axes that make sense for the "set/unset logscale" commands. Previously, commands like "set logscale tuv" were silently accepted, leading to strange internal state. * src/plot2d.c: Issue an error message if the user tries to plot in polar mode with a style that is not supported. Bug #3072150 * src/axis.h (AXIS_INIT2D) src/set.c (set_logscale): Keep AXIS.log_base in sync with AXIS.base. Otherwise calls to AXIS_DO_LOG or AXIS_UNDO_LOG prior to the first plot command cause divide-by-zero or other math errors. 2010-11-07 Peter Juhasz <juhaszp@users.sourceforge.net> * src/datafile.c (df_readascii): The "labels" style did not work with pseudocolumns (e.g. "using 1:2:0"). Now it correctly handles pseudocolumns 0, -1, -2. * term/cairo.trm: Documentation fix: the section on the default size for the pngcairo terminal was incorrect. 2010-11-06 Peter Juhasz <juhaszp@users.sourceforge.net> * src/plot3d.c src/plot3d.h src/set.c src/show.c src/save.c docs/gnuplot.doc demo/kdensity2d.dem: New option "kdensity2d" for "set dgrid3d" to create two-dimensional kernel density plots. 2010-11-03 Shigeharu Takeno <shige@iee.niit.ac.jp> * docs/gnuplot.doc: typos * docs/term-ja.diff docs/gnuplot-ja.doc: Sync Japanese documentation to gnuplot.doc rev 1.633 2010-11-02 Michael Murphy <murphy-md@users.sourceforge.net> * share/LaTeX/gnuplot-lua-tikz.sty: Change the tikz default linetype 0 axis style from dashed to dotted, and the color from black to 35% black. Tracker item #3098162 2010-10-31 Petr Mikulik <mikulik@physics.muni.cz> * demo/pm3dcolors.dem: Added first page with multiple palettes. Show color ranges in [0:1]. 2010-10-28 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (plot_boxes): Prevent out-of-range boxes from creating degenerate invisible boxes in the output file. Can reduce file size for vector format output. Bug #3096750 * src/axis.c: The custom routine dbl_raise() was failing to handle NaN correctly, causing an infinite loop from e.g. set yrange [*:NaN] Replace it with a call to the C library routine pow(). 2010-10-26 Ethan A Merritt <merritt@u.washington.edu> * src/misc.c (parse_fillstyle): Allow "border" as a keyword without necessarily having an immediately following linetype or color. * src/plot2d.c (eval_plots): fillcolor was not taking into account user-defined linetypes. * src/plot3d.c src/misc.c: Simplify calls to load_linetype() * lisp/gnuplot.el: Emacs 24 does not have make-local-hook contributed patch #3095458 * ChangeLog.2: Split off ChangeLog at the point 4.5 was tagged. * docs/gnuplot.texi: regenerate from gnuplot.doc v 1.633 2010-10-23 Ethan A Merritt <merritt@u.washington.edu> * configure.in: The AC_CHECK_LIB macro apparently always appends to LIBS (despite what the documentation says). We want to accummulate readline-associated libraries in TERMLIBS rather than LIBS, so save and restore LIBS around the checks. 2010-10-21 Ethan A Merritt <merritt@u.washington.edu> * src/plot2d.c (boxplot_range_fiddling): trap and report an error if the x coordinate of a boxplot is undefined. Bug #3092435 * src/plot2d.c (get_data): Up until now this routine has returned the number of lines from which data were read, including lines containing undefined points. Change this to return the number of well-defined data points. That way a file of junk is recognized as empty if read with either 'using 1:2' or 'using ($1):($2)'. Bug #3092435 2010-10-20 Graham Reed <greed@users.sourceforge.net> * configure.in src/alloc.c: Test at configuration time whether the local implementation of malloc(0) returns 0 rather than a pointer. If so, work around it in gp_malloc(). Replaces alpha-specific fix of 2010-10-04. 2010-10-18 Ethan A Merritt <merritt@u.washington.edu> * src/plot2d.c (box_range_fiddling) src/graphics.c (plot_boxes): Catch a couple of corner cases of "plot ... with boxes". Bug #3075938 2010-10-14 Ethan A Merritt <merritt@u.washington.edu> * src/axis.c (gen_tics): A smart (or maybe that's dumb) compiler may optimize out our tests for step size less that the machine precision. Try to forestall this by marking the steps as (float)(volatile double). Bug #3085168 2010-10-12 Ethan A Merritt <merritt@u.washington.edu> * src/pm3d.c: Reduce the size of the pm3d surface quadrangle structure by removing a redundant copy of the vertex coordinates. Add a pointer to track the current plot's line color. Bug #2997853 2010-10-11 James R. Van Zandt <jrvz@comcast.net> * src/specfun.c src/specfun.h src/eval.c docs/gnuplot.doc: Adding support for the exponential integral E_n(x) as gnuplot function expint(n,x). 2010-10-10 Tatsuro Matsuoka <tmacchant3@yahoo.co.jp> * src/stdfn.c (not_a_number): Bit-pattern definition of NaN for MINGW 2010-10-09 Ethan A Merritt <merritt@u.washington.edu> * term/lua.trm (LUA_options): Null-terminate the "set term lua ..." command string at the first semicolon before passing it to lua. * src/fit.c src/fit.h src/set.c docs/gnuplot.doc: New option "set fit quiet" prevents fit information sent to the log file from being echoed also to stderr. Bug #2355210 2010-10-07 Ethan A Merritt <merritt@u.washington.edu> * src/gplt_x11.c: Protect against the case that the x11 colormap is not partitioned identically to the palette. 2010-10-06 Marco Cammarata <marcocamma@users.sourceforge.net> * docs/psdoc/ps_symbols.gpi: "set angle radian" 2010-10-06 Ethan A Merritt <merritt@u.washington.edu> * src/color.c src/pm3d.c src/pm3d.h set.c show.c docs/gnuplot.doc: Simplify the syntax for "set pm3d hidden3d". A linestyle is no longer required. If no linestyle is given, the line properties are taken from the plot command line. Bug #2997853 2010-10-05 Ethan A Merritt <merritt@u.washington.edu> * src/getcolor.c (quantize_gray) src/getcolor.h src/gplt_x11.c: Continuation of defined palette revamp (2010-10-01). Break out the new code into a separate subroutine that can be shared with gnuplot_x11. * src/color.c (draw_inside_color_smooth_box_bitmap): Assign colors to component colorbox rectangles by rounding the pixel coordinate up rather than down. This empirically gives better results in gd.trm, and doesn't seem to hurt other terminals. * term/post.trm term/pslatex.trm term/svg.trm term/PostScript/cp1251.ps src/term_api.h src/term.c docs/gnuplot.doc: Add support for codepage 1251, an alternative 8-bit Cyrillic encoding. 2010-10-04 Matthew Biggar <biggarm@users.sourceforge.net> * src/Makefile.am src/alloc.c: Architecture (Alpha) specific work- around to insure that gp_malloc() does not fail on error if 0 bytes are successfully allocated. 2010-10-02 Ethan A Merritt <merritt@u.washington.edu> * src/stdfn.c (not_a_number): Although DJGPP version 2.04 is reported to support atod("NaN"), this version is not universal. Switch to using an explicit bit pattern for NaN. 2010-10-01 Ethan A Merritt <merritt@u.washington.edu> * src/plot2d.c (cp_free): Prevent use-after-free error if a plot structure containing dynamically allocated data is reused for a later plot. * src/color.c (make_palette) src/getcolor.c (rgb1maxcolors_from_gray) docs/gnuplot.doc: Revamp the interaction of `set palette maxcolors` and defined palettes. Up until now, `set palette maxcolors N` meant both "allocate N colors" and "divide the color range into N equal parts". This meant that a user-defined palette that used unequal divisions of the total range interacted badly with a limited number of palette colors. Now we guarantee that in the case of defined palette ranges, a gray value is never mapped to a color outside its proper range even if the ranges are very unevenly spaced. If more color ranges are defined than the value of maxcolors, this may (or may not) result in increasing the effective value of maxcolors. Outboard terminals that enforce maxcolors (e.g. x11) do not yet benefit from this change. * configure.in src/datafile.c src/eval.c src/plot.c src/show.c term/lua.trm: Remove conditional flag HAVE_ISNAN. Apparently we have been getting along OK with an unprotected call to isnan() since Oct 2009. That would seem to be good evidence that we can remove the #ifdef protection elsewhere as well. 2010-09-30 Peter Juhasz <juhaszp@users.sourceforge.net> * src/plot2d.c (store_label eval_plots): Fix bug introduced by my patch of 2010-09-08 (references to uninitialized variables were found by valgrind). 2010-09-29 Ethan A Merritt <merritt@u.washington.edu> * src/color.c (draw_inside_color_smooth_box_bitmap): The color box is constructed from 128 segments. If any of these straddles a boundary within a defined palette, split it into 2 segments so that discrete color transitions are described with pixel accuracy. This does not fix imprecision in the palette itself, which can result if too few colors are allocated (set palette maxcolors). 2010-09-28 Petr Mikulik <mikulik@physics.muni.cz> * docs/titlepage.ipf docs/titlepage.tex: Years updated. 2010-09-28 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (plot_image_or_update_axes): Add support for log-scale transformation of 2D image data. * src/hidden3d.c: Disentangle variable color from the direction of arrows. Bug #3074212 2010-09-28 Volker Dobler <vdobler@users.sourceforge.net> * src/axis.c (load_one_range load_range) src/axis.h src/parse.c src/parse.h src/save.c src/set.c src/unset.c src/util.c demo/all.dem demo/autoscale.dem docs/gnuplot.doc: Introduce a mechanism for constraining the axis limits chosen during autoscaling. For example: set yrange [* : 100<*<200] constrains autoscaling on y such that the upper range limit must fall between 100 and 200. 2010-09-27 Peter Juhasz <juhaszp@users.sourceforge.net> * src/datafile.c (f_stringcolumn): The stringcolumn function didn't recognize columns 0, -1, and -2. Now it treats them the same as the column function does. 2010-09-27 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (apply_head_properties): Simplify the arrowhead code. * src/graph3d.c src/hidden3d.c src/util3d.c src/util3d.h: Provide a 3D wrapper apply_3dhead_properties() that dummies up an x-axis scale so that the 2D routine apply_head_properties() can be shared by 3D code. Bug #3074212 * src/term.c (do_arrow): To do proper foreshortening of 3D arrowheads would require a new approach. As an approximation, assume that any short arrow with a big arrowhead is the result of foreshortening. This affects 2D arrows also, but the visual effect is not bad. 2010-09-26 Ethan A Merritt <merritt@u.washington.edu> * src/command.c (replotrequest): Once we have started to replot, the previous data no longer exists. Therefore we must set refresh_ok = 0. 2010-09-23 Ethan A Merritt <merritt@u.washington.edu> * src/axis.c (axis_checked_extend_empty_range): When extending from an empty range, don't invert the axis direction by accident. Bug #3074365 2010-09-20 Ethan A Merritt <merritt@u.washington.edu> * src/plot2d.c (store2d_point): Allow the use of "with circles" in polar coordinate mode. * src/plot2d.c (get_data): The combination of smoothing and variable color cannot work in general. Disable variable color for all smoothed curves. Later we may add back support for the case of lc palette z. Bug #3063366 * src/graphics.c (fill_between): Fix filled curve clipping error. Bug #2963485 2010-09-19 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (edge_intersect): If for some reason we fail to find find the intersection points of a vector both of whose ends are out of range, issue a warning, pick an edge, and continue. I can't see any good reason to treat this as a fatal error. Bug #2824879 * docs/gnuplot.doc: Clarify the section on linetypes and linestyles. 2010-09-18 Ethan A Merritt <merritt@u.washington.edu> * src/eval.c src/internal.c src/internal.h docs/gnuplot.doc: New function value("X") returns the value of a variable named X. A = "foo" value("A") returns "foo" value(A) returns NaN, because there is no variable named foo value(2) returns 2 (numeric expressions have a natural value) Among other things, this allows you to read variable names from a data file and use the current value of those variables in a plot. * src/util.c (gprintf): Handle formats x/X/o/O for values that overflow (int) by switching to llx/llX/llo/llO and (long long). NB: This does _not_ extend the representation of negative numbers to 64 bits unless the representation overflows 32 bits. 2010-09-16 Ethan A Merritt <merritt@u.washington.edu> * tutorial/eg2.plt tutorial/eg6.plt tutorial/test_tikz.plt tutorial/Makefile.am.in tutorial/header.tex tutorial/tutorial.tex: Update the LaTeX tutorial a bit. More could be done. 2010-09-15 Ingo Thies <ingo.thies@gmx.de> * src/graph3d.c src/graph3d.h src/mouse.c src/set.c src/unset.c: Switch the middle button left/right mouse zoom behaviour in 3D plots so that the zoom response is logarithmic. 2010-09-15 Shigeharu Takeno <shige@iee.niit.ac.jp> * term/gd.trm: As of libgd 2.0.36 you can now specify a TrueType font using either Fontconfig syntax or using the font file name directly. But switching from one form to the other was only possible as an option of "set terminal". This patch enables us to specify these two forms of the font name in "set title", "set xlabel", and so on. 2010-09-15 Ethan A Merritt <merritt@u.washington.edu> * src/term_api.h src/term.c (strlen_tex): Add a special-case routine to estimate the true number of output characters in a LaTeX string containing markup. This is not a real LaTeX parser, but even a poor estimate is better than just calling strlen(). Bug #1603348 and others * term/latex.trm term/lua.trm term/pslatex.trm: Set flag TERM_IS_LATEX so that strings passed to these terminals are sent to strlen_tex() rather than the normal enhanced text string length estimation. 2010-09-10 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (boundary): When calculating the horizontal space required for x axis tick labels, we must ignore ticks that are outside the current axis range. * src/mouse.c (apply_zoom): Tick labels generated by 'using xticlabels(N)' may have changed while the plot was zoomed, so we must preserve them when un-zooming. 2010-09-08 Ethan A Merritt <merritt@u.washington.edu> * src/datafile.c (df_close): Free matrix data that was stored in memory during input. Otherwise we leak memory after every plot of matrix data. * src/color.h src/gadgets.c src/gadgets.h src/misc.c src/term.c src/term_api.h: Repair some lp_style_type definitions and initializers that were incorrect or incomplete. 2010-09-08 Peter Juhasz <juhaszp@users.sourceforge.net> * src/plot2d.c (store_label eval_plots): Extend variable color support for LABELPOINTS style by allowing "with labels tc X lc Y" where X, Y is one of "lc variable", "lc palette z", or "lc rgb variable". * src/misc.c (lp_parse): Revert the patch of 2010-07-08 because it accidentally disabled the coloring option "lc N". * src/graph3d.c (key_sample_line_pm3d key_sample_point_pm3d): More correct fix to bug #3026477: the functions above failed to call the simpler key sample routines in case of plots with coloring option "lc N" and "lc rgb 'color'". 2010-09-06 Shigeharu Takeno <shige@iee.niit.ac.jp> * docs/term-ja.diff docs/gnuplot-ja.doc: Sync Japanese documentation to gnuplot.doc rev 1.623 2010-09-04 Peter Juhasz <juhaszp@users.sourceforge.net> * src/set.c (set_logscale): Removed arbitrary limitation for log base (was >= 1.1, now > 1.0) 2010-09-03 Ethan A Merritt <merritt@u.washington.edu> * src/readline.c (readline): Fix Windows breakage (failure to recognize ^M as newline) caused by error in OSK code removal. 2010-08-31 Petr Mikulik <mikulik@physics.muni.cz> * src/os2/gnupmdrv.rc: Removed menu item Commands to clipboard. * src/gpexecute.c (gp_execute): Removed bSend2gp and call to TextToClipboard. * src/mouse.c (alert): Use DosBeep under OS/2. * os2/gclient.c: Removed unused #define GNUPMDRV. 2010-08-30 Ethan A Merritt <merritt@u.washington.edu> * src/show.c (conv_text): Until now, the "show" and "save" commands have replaced all non-ascii characters with a byte-by-byte octal escape sequence. This makes any labels, variables, titles, etc not human-readable if they contain UTF8 encoded characters. Now we simply pass them through as-is if the current encoding is UTF-8. I think this is the correct thing to do for other 8-bit encodings as well, but I can't test those easily. 2010-08-25 Ethan A Merritt <merritt@u.washington.edu> * src/plot2d.c (eval_plots): Allow "fc <colorspec>" as an in-line option to the plot command for plot styles that use a fill. 2010-08-14 Ethan A Merritt <merritt@u.washington.edu> * src/gplt_x11.c: The gnuplot_x11 side of Shige's fix. 2010-08-14 Shigeharu Takeno <shige@iee.niit.ac.jp> * term/x11.trm: The last font used inside an enhanced text string was not being cleared on exit. 2010-08-13 Ethan A Merritt <merritt@u.washington.edu> * src/ansichek.h src/gplt_x11.c src/plot.c src/readline.c src/show.c src/stdfn.h src/syscfg.h term/x11.trm: Remove conditional code for another obsolete platform (OSK/OS9, used for example on TRS-80). 2010-08-12 Ethan A Merritt <merritt@u.washington.edu> * src/command.c: OSX history command could segfault if there was no previous history file. * docs/gnuplot.doc: Reorganize documentation for binary files. 2010-08-09 Ethan A Merritt <merritt@u.washington.edu> * configure.in src/plot.c: More work to enable autoconfigue on OSX. 2010-08-08 Olivier Mehani <shtrom@users.sourceforge.net> * src/util.c docs/gnuplot.doc: Add ISO-IEC-80000 prefixes (ki Mi Gi etc) as gprintf format specifiers %b and %B, which are respectively the mantissa and exponent. Also fix an out-of-range formatting bug. 2010-08-07 Ethan A Merritt <merritt@u.washington.edu> * src/plot2d.c: Do not create a data record for a blank line at the end of the input stream. Bugfix. * src/plot2d.c (eval_plots): Update GPVAL_DATA values after plot in tabulate mode just as for normal plotting mode. Bug #3041233 * docs/gnuplot.doc src/gadgets.h src/graphics.c src/save.c src/set.c src/show.c src/tables.c src/tables.h: New option "set key opaque". If requested, the code makes two passes over each 2D plot command. The actual graph is drawn during the first pass, and the key box with plot samples is drawn during the second pass. 2010-08-05 Ethan A Merritt <merritt@u.washington.edu> * configure.in src/command.c src/history.c src/mouse.c src/plot.c src/show.c: Finally a work-around for the broken libreadline on OSX, which is really a wrapper for some version of libeditline. Test for each potentially missing function in configure and deal with it if it's missing. There may still be an issue with autoconfiguring support for the history functions. Bug #1839048 and others 2010-07-30 Ethan A Merritt <merritt@u.washington.edu> * src/command.c src/command.h src/eval.c src/fit.c src/gp_types.h src/plot.c src/readline.c src/stdfn.c src/syscfg.h src/term.h: Remove vestigial tests for DOS16 or DOS386 2010-07-29 Allin Cottrell <cottrell@wfu.edu> * src/term.c src/term_api.h term/emf.trm term/svg.trm docs/gnuplot.doc: Add support for codepage 950, which is Microsoft's version of Chinese Big5 encoding. Only the emf terminal (and maybe svg) do anything useful with it. "set encoding cp950" 2010-07-28 Ethan A Merritt <merritt@u.washington.edu> * term/estimate.trm: Always estimate escaped characters as requiring one character width. Bug #3036010 2010-07-27 Tim Mooney <enchanter@users.sourceforge.net> * configure.in: If lua.pc is not present but liblua.so is found anyhow, then set HAVE_LUA and LUA_LIBS explicitly. Bug #3035608 2010-07-26 Shigeharu Takeno <shige@iee.niit.ac.jp> * term/win.trm src/win/wgraph.c: Yet another windows terminal font fix. Bug #2972307 2010-07-25 Ethan A Merritt <merritt@u.washington.edu> * term/canvas.trm: "set term canvas fontscale <fs>" * src/graphics.c (do_plot do_key_layout): Separate out the code that allocates space for the graph legend, and collect the key sample code into a single place. 2010-07-15 Shigeharu Takeno <shige@iee.niit.ac.jp> * docs/gnuplot.doc: typos * docs/term-ja.diff docs/gnuplot-ja.doc: Sync Japanese documentation to gnuplot.doc rev 1.617 2010-07-14 Ethan A Merritt <merritt@u.washington.edu> * src/hidden3d.c: Remove magic number -3 and the test (foo>=-2) in favor of LT_NODRAW and test (foo!=LT_NODRAW). * src/hidden3d.c: #define PT_ARROWHEAD and PT_BACKARROW * src/hidden3d.c (make_edge draw_edge build_networks) src/util3d.c (draw3d_line_unconditional): Handle arrow heads and other arrow style parameters in hidden3d mode. For surfaces, edge.style indicates whether this edge is seen from the top or the bottom. Coopt this flag for VECTOR plots to indicate whether the vector points up (positive z) or down (negative z). Separate flag is needed because the end points are sorted on z. 2010-07-11 Peter Juhasz <juhaszp@users.sourceforge.net> Ethan A Merritt <merritt@u.washington.edu> * src/util3d.c (draw3d_point_unconditional): Remove incomplete local color handling; the shared code in term_apply_lp_properties now does a more complete job. * src/graph3d.c (do_3dplot): Simplify the key sample code for contour plots with style "points". Set a default color sequence for contours belonging to a surface drawn with "lc variable". 2010-07-10 Ethan A Merritt <merritt@u.washington.edu> * src/graph3d.c (do_3dplot): Fix bug introduced by patch of 23-Mar-2010. If the linetype of a 3D surface used "lc ..." then all contours of the surface were stuck with that same coloring rather than incrementing through successive line types. 2010-07-09 Ethan A Merritt <merritt@u.washington.edu> * src/term.c (term_apply_lp_properties): Yet another bandaid fix for problems with "lc var". If the higher level code has failed to resolve LC_COLORFROMCOLUMN (or LT_DEFAULT) into an actual color, use LT_BLACK. Bug #3026477 2010-07-08 Ingo Thies <ingo.thies@gmx.de> * src/gadgets.h src/mouse.c src/set.c: Allow continuous rotation of 3D plots when mousing; i.e., do not limit rotation angle to 0<rotx<180 2010-07-08 Ethan A Merritt <merritt@u.washington.edu> * src/misc.c (lp_parse): The coloring option "lc N" should not set a use_palette flag. I think the option "lc variable" shouldn't either. Bug #3026477 2010-07-07 Peter Juhasz <juhaszp@users.sourceforge.net> * src/datafile.c src/gadgets.c src/gadgets.h src/gp_types.h src/graph3d.c src/graphics.c src/graphics.h src/plot2d.c src/save.c src/set.c src/show.c src/tables.c src/tables.h src/unset.c: * docs/gnuplot.doc docs/plotstyles.gnu demo/all.dem demo/ellipses.dat demo/ellipses_style.dem demo/orbital_elements.dat demo/orbits.dem New plot style "with ellipses". Demos and documentation to match. 2010-07-07 Ethan A Merritt <merritt@u.washington.edu> * term/PostScript/prologue.ps: Add a default definition /g {setgray} def so that a missing palette initialization will result in normal grayscale rather than an invalid PostScript file. Bug #3026477 2010-07-06 Ethan A Merritt <merritt@u.washington.edu> * src/graph3d.c (boundary3d): Prevent infinite loop or divide-by-zero if the requested plot is so small that x or y dimension goes to zero. Bug #3026145 2010-07-05 Akira Kakuto * term/win.trm: More fixes to font initialization. Bug #2972307 #2993504 2010-07-02 Shigeharu Takeno <shige@iee.niit.ac.jp> * term/win.trm: Explicitly initialize font. Bug #2972307 2010-07-01 Ethan A Merritt <merritt@u.washington.edu> * src/datafile.c (df_readbinary): Regardless of the current timefmt setting, if we are reading time data from a binary file it will come in as a floating point value rather than as a string. So we can treat it like any other binary value. Thanks to Thomas Sefzick for pointing this out. * src/datafile.c (df_readbinary): In binary mode, string-valued functions were silently ignored. Fix this, thus allowing binary files to be plotted "with labels". For example: plot 'foo' binary format='%double' using 0:1:("A") with labels 2010-07-01 Ethan A Merritt <merritt@u.washington.edu> * docs/gnuplot.doc src/axis.h src/command.c src/datafile.c src/gp_time.h src/internal.c src/time.c: Track time coordinates to sub-second precision. Time data read using the %S format specifier in "set timefmt" is now treated as a floating point number rather than an integer. This affects data read from an input file ("set xdata time"), the axis range and tic locations given for an axis using time coordinates ("set xrange", "set xtics"), and time conversions performed via calls to strptime(). Time data output formats ("set format" strftime()) now accept a precision modifier to the %S format. For example, "%H:%M:%.3S" will print hour, minute, seconds to a precision of milliseconds. gnuplot> print strftime("%Y %D %H:%M:%.3S", 12345.6789) 2000 01/01/00 03:25:45.679 The maximum precision allowed for output is 6 digits (microseconds). 6 digit accuracy is possible for absolute dates through the year 2550. 2010-06-30 Ethan A Merritt <merritt@u.washington.edu> * src/plot2d.c (get_data): Add back the rather useless code that handles four columns of data for styles LINESPOINTS and POINTSTYLE, even though the variable color handling no longer needs it. It is still called (foolishly) if the plot command is issued with no using spec at all. 2010-06-29 Peter Juhasz * docs/gnuplot.doc: Document variable color for plot styles that were not previously supported. * src/plot2d.c: The final piece of "with labels tc variable" 2010-06-29 Ethan A Merritt <merritt@u.washington.edu> * src/set.c (parse_label_options) src/plot2d.c (store_label) src/pm3d.c (set_plot_with_palette): Finish variable color support for text color in LABELPOINTS. 2010-06-28 Peter Juhasz * src/graphics.c demo/varcolor.dem: Finish variable color support for plot style CANDLESTICKS. Expand the demo. 2010-06-28 Ethan A Merritt <merritt@u.washington.edu> * src/color.h: New flag TC_VARIABLE (only used for textcolor) * src/misc.c (parse_colorspec) src/set.c (set_key) src/graphics.c (do_key_sample): Accept "set key tc variable" 2010-06-27 Peter Juhasz * src/graphics.c src/plot2d.c: Remove dead code supporting the old way of handling variable color. Make "lc palette z" work. Since the new variable color mechanism frees up space in struct coordinate, use this to clean up the data storage for "with circles". * demo/varcolor.dem: General demo and debugging tool for the expanded support of variable color across almost all plot styles. * src/graphics.c src/plot2d.c: Implement variable color for *ERRORBARS, *ERRORLINES, FINANCEBARS, CANDLESTICKS 2010-06-27 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.h src/graphics.c plot2d.c: Maintain a dynamically- allocated array of per-datapoint color values in the header of each 2D plot. The array is allocated only if the plot uses variable color. * src/plot2d.c: Store variable color data in the plot->varcolor[] array for plot styles VECTOR CIRCLES BOXES LINES DOTS IMPULSES POINTSTYLE LINESPOINTS XYERRORLINES XYERRORBARS BOXXYERROR LABELPOINTS BOXERROR * src/graphics.c (check_for_variable_color): Convert this routine to check and load variable color using the new mechanism. Add variable color support for BOXXYERROR, BOXERROR 2010-06-26 Peter Juhasz * src/plot2d.c: In plots style "with circles", let a negative value for the radius indicate that the default radius should be used. 2010-06-24 Ethan A Merritt <merritt@u.washington.edu> * src/gadgets.c src/gadgets.h src/graphics.c src/plot2d.c src/save.c src/set.c src/show.c src/tables.c src/tables.h src/unset.c docs/gnuplot.doc: New style element "set style circle radius <R>" specifies a default radius for function plots or 2-column data plots drawn "with circles". 2010-06-16 Ethan A Merritt <merritt@u.washington.edu> * src/plot2d.c (eval_plots): Function plots should not be affected by the current setting of "boxwidth" unless they really do contain boxes. Bugfix 2010-06-15 Ethan A Merritt <merritt@u.washington.edu> * src/datafile.c: Do not allow xticlabels(foo) in association with style BOXPLOT, since there are no x coordinates. * src/gadgets.h: Add in missing fields of object initializers. 2010-06-11 Peter Juhasz * src/graphics.c (boundary): More correct fix for distorted vertical size of subplots in a multiplot. 2010-06-10 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (boundary): Fix a type that can distort the vertical size of subplots in a multiplot. 2010-06-02 Ethan A Merritt <merritt@u.washington.edu> * src/misc.c (need_fill_border): The fillstyle border color was not taking account of linetype redefinitions. 2010-05-30 Ethan A Merritt <merritt@u.washington.edu> * docs/gnuplot.doc: Document recently added %s time format (seconds since start of 2000). 2010-05-24 Ethan A Merritt <merritt@u.washington.edu> * src/graph3d.c (do_3dplot): Remove a restriction that limited depth- sorting of pm3d surfaces to those which were adjacent in the splot command. If there was a reason for the original restriction, that reason is now not remembered. Bug #3004793 2010-05-23 Ethan A Merritt <merritt@u.washington.edu> * term/emf.trm: Revise the enhanced text mode, especially text rotation. 2010-05-22 Ethan A Merritt <merritt@u.washington.edu> * term/canvas.trm (CANVAS_graphics ENHCANVAS_FLUSH): Fix a bug in applying the baseline of rotated enhanced text. Provide a dummy gnuplot_init() routine if a standalone html file with no mouse support is created. 2010-05-20 Ethan A Merritt <merritt@u.washington.edu> * term/estimate.trm (ENHest_writec strlen_utf8) src/term.c (estimate_strlen): Teach estimate_strlen() to handle UTF-8 encoded strings. The estimate is imperfect, but then again the estimate is already imperfect for any proportional font. To truly do this more accurately would require customized implementations for each terminal type. Any unicode code point below 0x3000 is treated as requiring one character width; code points above 0x3000 are treated as requiring two character widths. 2010-05-16 Ethan A Merritt <merritt@u.washington.edu> * src/hidden3d.c (draw_edge): Add support for coloring lines in hidden3d mode using 'lc variable' or 'lc rgb variable'. 2010-05-13 Ethan A Merritt <merritt@u.washington.edu> * term/cairo.trm (cairotrm_options): The "noenhanced" option was broken by the patch of 2009-07-03. Fix it. * term/cairo.trm (cairotrm_put_text): Enhanced text was applying the fontscale twice. Fix it. 2010-05-11 Ethan A Merritt <merritt@u.washington.edu> * src/eval.c (magnitude): Optimize for the predominant case (no imaginary component). 2010-05-10 Ethan A Merritt <merritt@u.washington.edu> * term/post.trm (PS_set_font): set ... font ",size" was not working for non-enhanced text. Now it is. * src/plot2d.c (parametric_fixup) src/plot3d.c (parametric_3dfixup): Delete vestigial code for auto-generation of a parametric plot title. 2010-05-09 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de> * src/eval.c (magnitude): Yesterday's change breaks if the complex argument is {0,0}. 2010-05-08 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de> * src/eval.c (magnitude): Make implementation robust to overflows and underflows. 2010-05-06 David Marx <itsdmarx@users.sourceforge.net> * src/syscfg.h: Tweaked version of _bool support for Sun/Solaris 2010-05-06 Ethan A Merritt <merritt@u.washington.edu * term/cairo.trm (cairotrm_graphics): Handle the special case of streaming pdfcairo output to stdout. (Requires cairo version >= 1.2) Bug #578311 2010-05-05 Ethan A Merritt <merritt@u.washington.edu * term/post.trm src/term.c: Move a global declaration out of post.trm so that gnuplot can be built without including the postscript terminal. 2010-05-02 Thomas Sefzick <thse@users.sourceforge.net> * src/gadgets.h src/graphics.c src/save.c src/set.c set/show.c src/tables.c src/tables.h docs/gnuplot.doc: New options "set key maxcolumns N maxrows M" to manually adjust the automatic layout of items in the figure legend. Implemented for 2D plots only. 2010-05-02 Ethan A Merritt <merritt@u.washington.edu * configure.in src/save.c src/set.c src/show.c src/unset.c src/fit.c src/fit.h docs/gnuplot.doc config/config.os2 config/config.wc config/config.nt config/config.dj2 config/config.oww config/config.cyg config/config.amg config/config.mgw: Remove conditional flag GP_FIT_ERRVARS, default to "set fit errorvar". Tracker item #2985752 * src/misc.c (lp_parse): "lc variable" was being lost in some cases. Bugfix 2010-04-24 Ethan A Merritt <merritt@u.washington.edu * config.mgw config.cyg config.os2: Enable HIDDEN_QUADTREE by default. Tracker item #2990173 2010-04-20 John Naylon <jpbn@users.sourceforge.net> * src/gp_types.h src/interpol.c src/plot2d.c src/tables.c docs/gnuplot.doc: New option "smooth cnormal", equivalent to "smooth cummulative" with automatic normalization to the range [0:1]. 2010-04-12 Ethan A Merritt <merritt@u.washington.edu * term/post.trm: Correct a typo that leads to serious problems with font size and placement (introduced by the fontscale code). 2010-04-04 Ethan A Merritt <merritt@u.washington.edu * term/cairo.trm: The cairo terminals were forgetting fontscale after the initial application. Bugfix * src/wxterminal/gp_cairo.c term/cairo.trm: Use-after-free error caused a segfault on certain enhanced text strings. Bug #2947223 2010-03-28 Ethan A Merritt <merritt@u.washington.edu * docs/gnuplot.doc: State explicitly that the timefmt %y interprets a 2 digit year number as being in the range 1969-2068. 2010-03-24 Ethan A Merritt <merritt@u.washington.edu * term/tgif.trm (text_angle): Handle text rotation -270 same as +90. Bugfix 2010-03-23 Guy Mann <guydmann@gmail.com> * term/js/gnuplot_mouse.js (mouse_update): Repaint current canvas before each incremental update of the zoom box. 2010-03-22 Ethan A Merritt <merritt@u.washington.edu * src/misc.c (lp_parse): Re-write the lp_parse() routine to prevent the loading of a user-defined linetype from undoing other linestyle properties given earlier in the same command. * src/util3d.h src/util3d.c (draw3d_line_unconditional) src/hidden3d (draw_edge draw_line_hidden): The code was passing in top and bottom colors for the hidden3d routines as integer linetypes. But loading a whole linetype lost any line properties given explicitly in the splot command. Change this so that the top and bottom colors are passed as t_colorspec structures instead. 2010-03-21 Tommaso Vinci <ilbibi@users.sourceforge.net> * Provide Humlicek's approximation to the Voigt/Faddeeva function voigt(x,y) = \frac{y}{\pi} \int{\frac{e^{t^2}}{(x-t)^2+y^2}}dt 2010-03-20 Ethan A Merritt <merritt@u.washington.edu * NEWS src/hidden3d.c src/plot3d.c src/graph3d.c docs/gnuplot.doc: Add support for 'with impulses' in hidden3d code. Previously the manual said 3D impulses were drawn "from the xy plane" but the code did not follow this, drawing instead from zmin. Now the 3D code always draws impulses from z=0 just as the 2D code always draws from y=0. 2010-03-18 Ethan A Merritt <merritt@u.washington.edu * docs/gnuplot.doc: Add index entries and update description of mouse scrolling and hotkeys. 2010-03-17 Ethan A Merritt <merritt@u.washington.edu * plot.c (main): Initialize c_token to a legal value at the start of interactive input. * docs/gnuplot.doc src/set.c src/term_api.h src/wxterminal/wxt_gui.cpp src/wxterminal/wxt_term.h term/cairo.trm term/emf.trm term/gd.trm term/pdf.trm term/post.h term/post.trm term/wxt.trm: New terminal option "fontscale <scale>". This scale factor is applied to the nominal font size before use, so that you can scale the font size up or down in parallel with scaling the output page up or down. This is mostly relevant for hardcopy output or embedded figures. 2010-03-14 Ethan A Merritt <merritt@u.washington.edu * INSTALL config/README config/makefile.amg config/makefile.ami config/makefile.dj2 config/makefile.unx config/term_pc.h configure.in docs/Makefile.in docs/README docs/gnuplot.doc src/Makefile.am src/Makefile.maint src/amiga.c src/command.c src/command.h src/graph3d.c src/graphics.c src/graphics.h src/makefile.all src/makefile.awc src/plot.c src/scanner.c src/stdfn.c src/stdfn.h src/syscfg.h src/term.c src/term.h src/variable.c term/amiga.trm: Remove code specific to amiga platforms. 30 files changed, 43 insertions(+), 1941 deletions(-) * config/makefile.dj2 config/makefile.unx config/term_pc.h configure.in docs/doc2texi.el src/eval.c src/eval.h src/makefile.all src/makefile.awc src/plot.c src/syscfg.h src/term.c src/term.h term/apollo.trm term/gpr.trm: Remove code specific to support of Apollo workstations.

Get rid of the variable and test the plot header directly when needed. * term/emf.trm: Tweak empirical corrections for character widths. Additional thin character -, really thin chars i,.:;|! 2010-02-24 Peter Juhasz * src/save.c: The 'save' command was not correctly handling plot styles circles, image, or rgbimage.

Otherwise RGB fails if the user has loaded no colors. * term/gd.trm: Documentation for the mechanism for setting line colors in the 'set term' command is out of date, and anyhow the mechanism is needed only for the terminal background. Line colors can now be handled in terminal-independent commands. Revise the docs accordingly. 2010-02-23 Ethan A Merritt <merritt@u.washington.edu> * src/specfun.c (ibeta) docs/gnuplot.doc: The approximation used for the function ibeta(a,b,x) was taken from Abramowitz & Stegun. However we failed to document that it is only usable on the domain x < (a-1)/(a+b-2). Add this warning to the docs and make sure that the function itself returns a consistant error value (-1) if the domain or range is invalid. Bug #2957184 2010-02-22 Don Taber <dtaber@topaflyers.com> * src/win/wgraph.c (SelFont): After a font change, call do_string_replot("") so that it is immediately visible. 2010-02-18 Ethan A Merritt <merritt@u.washington.edu> * term/svg.trm: Use dynamic allocation for all font names. This prevents buffer overflow problems for very long font names. * term/post.trm: Truncate over-long font names rather than allowing buffer overflow. 2010-02-17 Christoph Junghans (ottxor) * configure.in plot.c: New configuration option to add local packager to list of contacts for bug reporting. Bug #2951583 2010-02-17 Ethan A Merritt <merritt@u.washington.edu> * src/term.c (do_arc): Avoid calling trunc() because some compilers are still back in the dark ages (pre C99). * configure.in: Change default installation directory for x11 resources to /etc/X11/app-defaults. Bug #1953742 2010-02-17 Benjamin Lindner <lindnerb@users.sourceforge.net> * src/plot.c (interrupt_setup): Ctrl+C crashes windows console build.

This caused ambiguity in the interpretation of '.E1'. Is it a strange representation of 0, or concatenation of a string variable E1? Resolve this with a new rule that a number with an initial '.' must continue with a digit. Bugfix 2010-01-28 Petr Mikulik <mikulik@physics.muni.cz> * src/command.c (pause_command): Fix "pause mouse" for gnuplot.exe on Windows. 2010-01-25 Ethan A Merritt <merritt@u.washington.edu> * INSTALL: Add section explaining the libreadline problem on OSX. 2010-01-25 Petr Mikulik <mikulik@physics.muni.cz> * src/win/wgraph.c (drawgraph pattern_bitmaps): Synchronize fill patterns of the Windows terminal with other terminals. 2010-01-16 Ethan A Merritt <merritt@u.washington.edu> * src/variable.c (loadpath_handler): Have "show loadpath" also list the environmental variable GNUPLOT_PS_DIR.

Add configuration option --without-latex Bug #2928310 2010-01-12 Ethan A Merritt <merritt@u.washington.edu> * term/pdf.trm: Always start a new path with a moveto. Bug #2930705 * src/plot2d.c (eval_plots): In generating points for a function plot, only x and y were guaranteed to be initialized. Now to be safe we initialize all fields. Bug #2930705 * src/plot2d.c (store2d_point): steps, fsteps, and histeps were incorrectly auto-scaling to yhigh (which is really variable color). Bug #2929314 2010-01-10 Ethan A Merritt <merritt@u.washington.edu> * docs/gnuplot.doc docs/plotstyles.gnu demo/boxplot.dem src/datafile.c src/gadgets.c src/gadgets.h src/gp_types.h src/graph3d.c src/graphics.c src/plot2d.c src/save.c src/set.c src/show.c src/tables.c src/tables.h src/unset.c: New plot style "with boxplot" and corresponding "set style boxplot". 2010-01-10 Shigeharu Takeno <shige@iee.niit.ac.jp> * docs/gnuplot-ja.doc docs/term-ja.diff: Sync Japanese documentation to gnuplot.doc rev 1.595 2010-01-10 <ottxor@users.sourceforge.net> * share/Makefile.am: Do not install x11 appdefaults file if no X11 support is selected.

Add a support for initializing NaN and GPVAL_NaN on Windows. Bug #2925544 2010-01-03 Ethan A Merritt <merritt@u.washington.edu> * src/datafile.c (df_readascii): Further revision to maintain the old behaviour of the string variables demo. The demo uses a very unusual method to read time strings from the input file, but let's not break it unless necessary. 2010-01-02 Ethan A Merritt <merritt@u.washington.edu> * src/datafile.c (df_readascii): Time format "%s" should be able to handle any numeric input. Convert input of the form 'using ($1)' or 'using (f($1))' to a string so that it can be passed to gstrptime(). Bug #2899511 2010-01-01 Ethan A Merritt <merritt@u.washington.edu> * term/PostScript/prologue.ps term/PostScript/prologues.h: Update version in PostScript headers. Define a user-configurable flag SuppressPDFMark. * term/post.trm: Re-arrange stuff in the prolog so that users can either set SuppressPDFMark to true in an individual file or make a permanent change by setting it in the shared prolog file. 2009-12-31 Ethan A Merritt <merritt@u.washington.edu> * src/command.c src/gadgets.c src/gadgets.h src/graph3d.c src/graphics.c src/misc.c src/plot2d.c src/plot3d.c src/set.c src/show.c src/tables.c src/tables.h src/term_api.h src/term.c src/unset.c src/util3d.c demo/tango_colors.gp docs/gnuplot.doc: Allow the user to redefine the properties of basic linetypes. The redefinitions are persistent; i.e. they are not affected by "reset". The command options are identical to those for "set style line". New command: set linetype N {various line properties} set linetype cycle M The new line colors and widths can be set to cycle after going through M linetypes. E.g. for M=8, the color of linetypes 9, 17, 25 ... are the same as that of linetype 1. 2009-12-30 Peter Kalinin <pkalinin@users.sourceforge.net> * term/metapost.trm (MP_options): The metapost terminal sets the line thickness for plots via drawoptions, then uses 'draw GPtext ...' to place the text. The draw inherits options from drawoptions, which results in altered thicknesses of lines. Replace 'draw GPtext' with 'addto currentpicture also GPtext'. 2009-12-30 Shigeharu Takeno <shige@iee.niit.ac.jp> * src/win/wgnuplib.h src/win/wgraph.c term/win.trm: Monochrome option of win terminal seems to have no effect. set term win mono plot x draws a red line. I think the timing of calling ReadGraphini() is not correct. This should be done only once on first entry before setting the terminal options. 2009-12-30 Thomas Sefzick <thse@users.sourceforge.net> * src/graph3d.c: Fix incorrect color assignment of contour lines when 'set style increment user' is set. 2009-12-28 Ethan A Merritt <merritt@u.washington.edu> * src/plot.c (get_data) src/graphics.c (plot_c_bars) src/tabulate.c (print_table) docs/gnuplot.doc: Allow an optional 6th column in CANDLESTICKS style that specifies the width of each individual candle. 2009-12-24 Thomas Sefzick <thse@users.sourceforge.net> * src/tabulate.c src/time.c: Support the "%s" format specifier to strftime as per the unix man page. If the output format string is exactly "%s" then 'output_number()' in 'src/tabulate.c' returns the number of seconds since the beginning of the epoch as a number. All other cases ("%s" in combination with any other character) are treated in 'time.c'. 2009-12-24 Ethan A Merritt <merritt@u.washington.edu> * src/tabulate: Fix buffer overflow. * configure.in: The cross-compilation patch causes a recursive definition of CC in docs/Makefile. I have attempted to fix this by revising the definition of CC_FOR_BUILD, but I don't know if this will break cross-compilation again. 2009-12-24 Robert Schwebel <r.schwebel@pengutronix.de> * configure.in docs/Makefile.in: When cross compiling gnuplot, build the documentation generation tools in docs/ with CC_FOR_BUILD (host compiler), not with the cross compiler. 2009-12-22 Ethan A Merritt <merritt@u.washington.edu> * src/win/wgraph.c (drawgraph: W_line_type): Change initial line template for LT_BACKGROUND to 0 (lt -1) rather than 1 (lt 0). Possible fix for bug #1952287 2009-12-19 Juergen Wieferink <wieferink@freenet.de> * src/command.c, src/command.h, src/misc.c, src/misc.h (lf_push, lf_pop): Save if-state. * src/command.c, src/command.h, src/misc.c, src/misc.h (lf_push, lf_pop, load_file, do_string): Refactor duplicate code from load_file() and do_string() into lf_push() * misc.h, misc.c: Add field cmdline to LFS to allow correct deallocation. Check for infinite recursion. * src/misc.c (prepare_call, expand_call_args, load_file): Refactor code related to the call command out of load_file(). * src/command.c (history_command): Use do_string() now that it can detect recursions. * command.c, command.h, plot.c: Remove eval_depth and reset_eval_depth(). The new recursion detection in lf_push() should supercede this. 2009-12-18 Ethan A Merritt <merritt@u.washington.edu> * src/tables.h src/tables.c src/show.c src/save.c src/graph3d.h: Move all the DGRID3D_* options into a shared table. * src/set.c: Replace the set_dgrid3d() routine with a version that uses a shared option table and handles input values contained in variables. * docs/gnuplot.doc: bring dgrid3d syntax into line with the code 2009-12-12 Ethan A Merritt <merritt@u.washington.edu> * docs/plotstyles.gnu demo/bldg.png demo/barchart_art.dem Makefile.am.in New demo showing a) input of png image using binary filetype=png b) rescaling rectangular images to act as plot elements 2009-12-11 Ethan A Merritt <merritt@u.washington.edu> * src/graphics.c (boundary): Tweak auto-placement of plot borders so that it is closer to what was used prior to version 4.2.4. This makes the right margin slightly wider than in 4.2.6, and the left margin slightly narrower. 2009-12-08 Ethan A Merritt <merritt@u.washington.edu> * term/emf.trm (ENHemf_put_text): Left/right/center justification of enhanced text was not taking into account the text angle. Now it does. Bugfix. * src/breaders.c (gd_filetype_function): Make load of jpeg or gif image conditional on support by the installed libgd. * src/unset.c (reset_command): Reset options to plot style filledcurve. Bug #2911203 2009-12-05 Ethan A Merritt <merritt@u.washington.edu> * src/command.c (undefine_command): 'undefine A* B' should not affect BFOO. Bugfix. * src/internal.c (f_mult): Check for integer overflow when performing internal integer multiplication. Bug #2908270 2009-12-04 Tatsuro Matsuoka <tmacchant3@yahoo.co.jp> * config/makefile.mgw config/makefile.cyg: Create installation directories $(DESTDIR)/$(GNUPLOT_PS_DIR) $(DESTDIR)/$(GNUPLOT_LUA_DIR) 2009-12-04 Ethan A Merritt <merritt@u.washington.edu> * src/datafile.c (df_open): The variables that track matrix and binary data input (df_matrix, df_num_bin_records) must be re-inititialized for every file. 2009-12-03 Ethan A Merritt <merritt@u.washington.edu> * src/set.c (set_margin): Limit range of set ?margin at screen <foo> to 0 < foo < 1. * src/datafile.c (f_stringcolumn) src/plot2d.c (eval_plots): Enforce restrictions on which plot types can accept matrix data. 2009-12-01 Ethan A Merritt <merritt@u.washington.edu> * config/makefile.cyg config/makefile.dj2 config/makefile.mgw config/makefile.os2 src/Makefile.am term/lua.trm term/Makefile.am.in: Install the script gnuplot-tikz.lua under $pkgdatadir rather than under $pkglibexecdir.
