2014-09-26 Ethan A Merritt <merritt@u.washington.edu>
* term/js/gnuplot_mouse.js: Typo in logical test for hypertext.
* src/axis.h src/save.c src/set.c src/show.c src/unset.c src/graphics.c
src/graph3d.c: set [*]tics {{no}enhanced}
2014-09-24 Bastian Maerkisch <bmaerkisch@web.de>
* src/win/wgraph.c term/win.trm: The windows terminal allowed users
to change linetypes via an ini file or with the help of a dialog. This
has been superseeded by the more general `set linetyoe` mechanism.
The old code is still available but only active with WIN_CUSTOM_PENS
defined during compilation.
* src/win/wgraph.c src/win/wgidplus.c: Accept zero point size.
Eliminates drawing of unwanted point symbols for labelled contours.
Bugfix
2014-09-24 Ethan A Merritt <merritt@u.washington.edu>
* term/aed.trm term/v384.trm
config/makefile.dj2 config/makefile.emx config/makefile.vms
configure.vms docs/doc2texi.el docs/Makefile.am src/makefile.all
src/makefile.awc src/term.h:
Remove obsolete terminals:
aed: pre-1980 display device ($15,000) with 500x500 pixels, 256 colors
v384: Vectrix VX 384 mid 1980s graphics display terminal ($5000) with
672x480 pixels, 512 colors
* src/interpol.c: Force the number of intervals used for interpolating
monotonic cubic splines ("smooth mcsplines") to be at least twice the
number of data points.
2014-09-22 Christoph Bersch <usenet@bersch.net>
* src/misc.c (parse_fillstyle): Remove order dependence of keyword
"transparent".
* term/lua.trm term/lua/gnuplot-tikz.lua:
Support RGBA linecolors and LT_NODRAW. Add a linewidth terminal option.
2014-09-20 Bastian Maerkisch <bmaerkisch@web.de>
* src/fit.c src/fit.h src/save.c src/set.c src/show.c src/unset.c
docs/gnuplot.doc demo/fit.dem: Remove xerrors option (which requires 3
columns) since it is not like the xerrorbars plot style (which requires 4).
Rename `noerrors` option to `unitweights`. Let the fit command default
to `unitweights`, i.e. do not interpret the last column of the using
spec as z-errors. Add a command `set fit v4|v5` to switch between
old-style command line syntax and the new one. Default to `v5`, but
`reset` does not change the current setting.
Note that this change is backward-incompatible with v5-rc1 and v5-rc2.
However it restores compatibility with v4, subject to the restriction
that all independent variables must appear in the "fit" command itself
(see below).
* src/fit.c: Ethan A Merritt - use the tally of dummy variable names
to detect version 4 syntax in which the last column of a using spec
contains zerror but no "*error" keyword is provided.
2014-09-18 Ethan A Merritt <merritt@u.washington.edu>
* src/fit.c src/parse.c src/parse.h (int fit_dummy_var[]):
Track the occurrence of dummy variable names in a fit command. This lets
us count the independent variables so long as they are not obscured.
fit f(x,y) 'data' using 1:2:3:4 # flags use of 'x' and 'y'
fit x*y 'data' using 1:2:3:4 # flags use of 'x' and 'y'
g(x) = x*y;
fit g(x) 'data' using 1:2:3:4 # flags 'x', doesn't notice 'y'
In each case fit_dummy_var[0] is 1. In the 3rd case fit_dummy_var[1]
is 0 but should be 1. Fixing this would be quite hard.
2014-09-18 Bastian Maerkisch <bmaerkisch@web.de>
* src/win/wgnuplib.h src/wgraph.c term/win.trm: windows terminal
supports the toggle command.
2014-09-18 Ethan A Merritt <merritt@u.washington.edu>
* src/datafile.c: Revised error message for datafile open failure.
2014-09-14 Ethan A Merritt <merritt@u.washington.edu>
* src/tables.c src/command.c src/command.h docs/gnuplot.doc:
New command `toggle {<plotno> | "plottitle" | all} has the same effect
as left-clicking on the key entry for a plot shown by an interactive
terminal (qt, wxt, x11).
2014-09-12 Bastian Maerkisch <bmaerkisch@web.de>
* src/mouse.c (xDateTimeFormat): Use ggmtime() instead of gmtime() to
avoid platform specific restrictions.
Bug #1470
2014-09-09 Pieter-Tjerk de Boer <p.t.deboer@utwente.nl>
* docs/gnuplot.doc: Update help on fit to new command syntax.
* src/fit.c: Fix init of num_errors.
2014-09-09 Akira Kakuto <kakuto@fuk.kindai.ac.jp>
* src/win/wpause.c (PauseBox): Do not wait for further events after
pause dialog box was closed. Bugfix.
2014-09-08 Christoph Bersch <usenet@bersch.net>
* demo/stringvar.dem docs/gnuplot.doc src/internal.c (f_word f_words):
Modify the word() and words() functions to recognize quoted strings
inside the top level string as single entities.
2014-09-08 Christoph Junghans <ottxor@users.sourceforge.net>
* configure.in: New option --without-libcerf
2014-09-08 Ethan A Merritt <merritt@u.washington.edu>
* src/misc.c (lp_parse parse_colorspec): Allow a quoted colorname to
immediately follow the keywords lc|linecolor|fc|fillcolor; i.e. in this
case the additional rgbcolor keyword is optional.
2014-09-07 Ethan A Merritt <merritt@u.washington.edu>
* src/plot2d.c: "set linetype 1 pt 'A'; plot x with lp" requires that
the plot->labels field be initialized before plotting.
* src/save.c: handle PT_CHARACTER when saving linetype
2014-09-05 Ethan A Merritt <merritt@u.washington.edu>
* src/term_src/api.h src/gadgets.c src/hidden3d.c src/misc.c
src/plot2d.c src/plot3d.c src/save.c src/set.c src/ show.c src/term.c:
The field lp_style_type.pointflag was variously used as a Boolean,
an integer, or a magic number indicating an uninitialized state.
Clean this up by replacing it with a bitfield lp_style_type.flags
with defined bits LP_SHOW_POINTS LP_NOT_INITIALIZED LP_EXPLICIT_COLOR.
This has the side effect of allowing a trivial fix for a regression
in 4.6.5 that caused "set hidden3d; splot ... lc <foo>" to ignore the
requested color. See Bugs #1284 #1475
2014-09-05 Karl Ratzsch <ratzsch@uni-freiburg.de>

Add a 2nd parameter to the API term->modify_plots(operations, plotno).
All terminals for which this entry point is not NULL are updated
accordingly. This patchset does not by itself add any new
functionality or change user-visible behavior. It prepares for later
adding command-line equivalents to mouse operations like "toggle".

* src/graphics.c (place_arrows) src/graph3d.c (place_arrows3d):
Revert arrowhead patch of 2014-08-18. Document that if you want a
dashed arrow shaft it is best to use "nofilled" for the arrow head.
Bugs #1460 #1476
2014-09-03 Ethan A Merritt <merritt@u.washington.edu>
* src/graph3d.c src/hidden3d.c: "splot ... with dots" was not drawing
the dots.
Bug #1474
2014-08-31 Ethan A Merritt <merritt@u.washington.edu>
* src/stats.c docs/gnuplot.doc: Calculate and report sample standard
deviation (STATS_ssd) as well as the population standard deviation
(STATS_stddev). Provide formulae for the reported quantities in the
LaTeX documentation, and document the difference between
_ssd and _stddev in all documentation formats.
* src/stats.c: In version 5 when there is no using spec df_readline()
always returns at most the number of columns present on the first line.
Bug #1472
2014-08-30 Petr Mikulik <mikulik@physics.muni.cz>
* config/config.os2: Use _strtoll.
2014-08-29 Petr Mikulik <mikulik@physics.muni.cz>
* src/gplt_x11.c (exec_cmd process_configure_notify_event):
Add missing #ifdefs: USE_X11_MULTIBYTE and PIPE_IPC.
2014-08-21 Ethan A Merritt <merritt@u.washington.edu>
* src/fit.c: Handle columnheaders in input to "fit".
Bug #1467
* src/misc.c (lp_parse): Flag "set object N lt <lt>" as an error,
since currently this must be done be "set object N fs bo <lt>".
Probably we should figure out how to make this command work, but
better to issue an error than accept it and then ignore it.
Bug #1460
* src/bf_test.c: Use HAVE_STDLIB_H and HAVE_MALLOC_H to include proper
header file for calloc(). "Jun T." <takimoto-j@kba.biglobe.ne.jp>.
2014-08-21 Ethan A Merritt <merritt@u.washington.edu>
* Branchpoint for 5.0 (cvs tag -b branch-5-0-stable)
The main (development) branch is now marked 5.1 and will eventually
be used as the basis for a future release named gnuplot version 5.2.
>>> NOTE <<<
Starting now
============
* Bugfixes for version 5 should be applied to both the main branch
(5.1 == this one) and the stable branch (branch-5-0-stable).
They will first appear in patchlevel releases 5.0.1, 5.0.2, and so on.
* Major new features and experimental changes belong here, not in the
stable branch. They will appear eventually in release 5.2.
* Minor new features can go in both branches at your discretion, but
remember that the stable branch should ideally never break.
That means new code should be tested here in the development
branch first, and only after testing be added or back-ported to the
stable branch.
2014-08-20 Ethan A Merritt <merritt@u.washington.edu>
* src/wxterminal/gp_cairo.c: Distinct empirical scale factors for
dashlength used by pngcairo, pdfcairo, and wxt.
* term/emf.trm: Scale dashlength with current linewidth.
2014-08-18 Ethan A Merritt <merritt@u.washington.edu>
* src/graphics.c (place_arrows) src/graph3d.c (place_arrows3d):
Only invoke the arrowheads only code if there really is an arrowhead.
2014-08-18 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* config/mingw/Makefile (VPATH): Drop $W from VPATH. Necessary to
avoid circular dependency on wgnuplot.mnu
(%.$(O)): Use pattern rule instead of VPATH to build Windows
source files.
(VERSIONING): Avoid inverted logic in makefile conditional.
(console, windows, pipes): Simplify by letting the default rule in
the sub-make handle things.
(default, all): Versioning is really needed by $(TARGET) rule,
so let that handle constructing it.
($(TARGET)): Do VERSIONING first, drop dependencies on icon files.
(%.o): Use pattern rules to build Qt source files. Much simpler
than spelling it out long hand for every single source file.
2014-08-15 Ethan A Merritt <merritt@u.washington.edu>
* src/bf_test.c src/Makefile.am src/binary.* (removed)
config/makefile.os2 config/makefile.dj2 config/makefile.cyg
config/cygwin/Makefile config/mingw/Makefile config/msvc/Makefile:
Remove bf_test dependence on all other gnuplot files and libraries.
This makes binary.c and binary.h superfluous.
Bugs #1412 #1451
* src/makefile.all src/makefile.awc: Remove mention of binary.o
* config/*/Makefile: Remove alloc and binary from bf_test dependencies
* src/graphics.c (place_objects) src/set.c (set_obj):
Apply default rectangle style at the time of a "set object rect"
command rather than waiting until the rectangle is drawn. This prevents
the default style line/dash settings from overriding explicit rectangle
commands.
Bug #1460
* src/save.c (save_linetype): Bugfix - dashtype was being saved only if
there was also a point type.
* src/gadgets.c (apply_pm3dcolor): Don't clobber current dashtype by
calling term->linetype(LT_BLACK). Call term->set_color(BLACK_COLORSPEC)
instead.
* src/graphics.c (place_arrows) src/graph3d.c (place_arrows3d):
Force solid lines for arrow heads.
2014-08-15 Shigeharu Takeno <shige@iee.niit.ac.jp>
* src/gplt_x11.c: For single byte fonts gnuplot_x11 uses a list of
previously used fonts to speed up the search for a new target font.
Now we add an equivalent for multi-byte font search.
2014-08-14 Ethan A Merritt <merritt@u.washington.edu>
* src/graphics.c (do_rectangle) src/graph3d.c (map3d_position_r)
demo/rectangle.dem: Fix y extent and clipping of rectangles with
negative y coord or inverted axes.
Bug #1462
2014-08-05 Ethan A Merritt <merritt@u.washington.edu>
* src/mouse.c (event_buttonpress): Remove extraneous event_reset.
2014-08-02 Ethan A Merritt <merritt@u.washington.edu>
* src/misc.c (parse_colorspec): Apply user-defined line colors
to text color also.
Bug #1452
src/misc.c src/save.c src/set.c src/term.c src/term_api.h:
Store custom dashtype string as a constant length character array
rather than a dynamically allocated string. This fixes memory
leakage that happened whenever a linetype using dashes was discarded.
2014-08-01 Ethan A Merritt <merritt@u.washington.edu>
* src/mouse.c (event_buttonpress): Trap mouse button click on
press rather than on release so that "pause mouse {button1|any}"
takes precedence over a key binding to the mouse button.
Bugfix
2014-07-30 Ethan A Merritt <merritt@u.washington.edu>
* term/x11.trm: Remove misleading mention of -noevents. This is a
command line option for gnuplot_x11, not for gnuplot itself.
* src/datafile.c docs/gnuplot.doc demo/heatmaps.dem:
New text input matrix keywords `columnheaders` and `rowheaders`.
These handle reading matrix data from a csv file in which the first
row and/or column contains labels rather than data.
* src/eval.c (update_plot_bounds): Provide a user-visible copy of
the current terminal scale (oversampling, etc) as GPVAL_TERM_SCALE.
Bug #1291
2014-07-28 Allin Cottrell <cottrell@wfu.edu>
* src/syscfg.h: Report 32/64 bit Windows build in version string
2014-07-28 Ethan A Merritt <merritt@u.washington.edu>
* src/wxterminal/gp_cairo.c: Do not pass a linewidth of zero to the
cairo library. The linewidth of LT_AXIS is now set in the core code,
do not further reduce it in gp_cairo_stroke().
2014-07-25 Ethan A Merritt <merritt@u.washington.edu>
* src/gplt_x11.c: Scale x11 dashlength with linewidth.
2014-07-23 Shigeharu Takeno <shige@iee.niit.ac.jp>
* src/mouse.c src/mouse.h src/set.c src/show.c docs/gnuplot.doc:
New command 'set mouse zoomfactors <xfactor>,<yfactor>'
2014-07-22 Ethan A Merritt <merritt@u.washington.edu>
* src/gp_types.h src/plot2d.c (store2d_point):
INRANGE/OUTRANGE refer to points that are inside/outside the plot
boundaries as defined by xrange, yrange, etc. They fail to handle
points that are outside theta range limits given for polar data.
That is, a point may be outside of trange [pi/2:pi] even though it
would lie well inside the plot boundaries if drawn.
Add a new category EXCLUDEDRANGE for such points.
* src/graphics.c (plot_impulses): Test for EXCLUDEDRANGE data points
so that set trange [theta_min:theta_max] actually does something.
Bug #1439
* demo/poldat.dem: Make sure trange includes the whole plot.
2014-07-18 Ethan A Merritt <merritt@u.washington.edu>
* demo/Makefile.am.in: Do not create a symlink to GNUPLOT_X11 in the
build directory during "make check". This was probably intended to
handle the rare case of ./configure --program-suffix=foo but it breaks
the more common case of configuring on a system without x11 support
and then running "make check" twice.
Bugfix
2014-07-14 Ethan A Merritt <merritt@u.washington.edu>
* src/gadgets.c src/save.c src/set.c src/gadgets.h:
Continue to recognize "set style increment user" even though it has
been deprecated in favor of "set linetype".
Bug #1411 (not really a bug)
2014-07-12 Ethan A Merritt <merritt@u.washington.edu>
* src/parse.c (check_for_iteration): Fix failure to detect some loop
[start:end:increment] combinations that should be executed only once
or not executed at all.
Bug #1441
2014-07-10 Ethan A Merritt <merritt@u.washington.edu>
* src/set.c (set_dummy): More sanity checks on "set dummy" syntax.
Bug #1442
2014-07-06 Ethan A Merritt <merritt@u.washington.edu>
* src/set.c (load_tic_user): "set Xtics ()" should clear the list
of user-specified tics rather than setting tic generation to auto.
2014-07-04 Shigeharu Takeno <shige@iee.niit.ac.jp>
* docs/gnuplot.doc docs/term-ja.diff docs/gnuplot-ja.doc
man/gnuplot.1 man/gnuplot-ja.1:
Fix typos. Sync Japanese documentation to 1.896
2014-07-04 Bastian Maerkisch <bmaerkisch@web.de>
* src/win/wgraph.c: 'q' closes graph window.
* src/qtterminal/qt_term.cpp (qt_options) term/wxt.trm (wxt_options):
On Windows, the wxt and qt terminals can be used in the same session.
2014-07-01 Ethan A Merritt <merritt@u.washington.edu>
* term/cairo.trm, term/wxt.trm:
Always report {no}enhanced property in "show term".
* src/color.c: If the current terminal has property "monochrome" then
convert all requests for constant color as "black".
Bug #1423
2014-06-24 Ethan A Merritt <merritt@u.washington.edu>
* src/set.c src/show.c src/tables.c docs/gnuplot.doc:
New command: set margins <left>, <right>, <top>, <bottom>
acts just like four successive commands set lmargin <left>, ...
* src/unset.c: unset margins
2014-06-20 Ethan A Merritt <merritt@u.washington.edu>
* configure.in src/wxterminal/wxt_gui.h: The configuration test for
wxWidgets >= 2.8 had no effect on code generation. Remove this test.
* configure.in src/wxterminal/wxt_gui.h: Revert the attemp to guess
whether -lX11 is required by wxt. As feared, this causes problems on OSX
and other platforms where wx is built on top of something other than X11.
2014-06-16 Karl Ratzsch <ratzsch@uni-freiburg.de>
* fit.c: FIT_NITER holds number of iterations used by previous fit.
2014-06-16 Ethan A Merritt <merritt@u.washington.edu>
* configure.in src/wxterminal/wxt_gui.h: wxWidgets versions > 2.8 want
the main program to call XInitThreads(), but fail to specify -lX11 in
wxt-config. So we force this ourselves. [=> reverted 2014-06-20]
Bug #1401
* src/graphics.c (xtick2d_callback): Clip r axis tics and tic labels to
the bounding box of the plot.
Bug #1290
2014-06-15 Dmitri A. Sergatskov <dasergatskov@gmail.com>
* configure.in: Add LRELEASE for Qt5 autoconfiguration
2014-06-15 Bastian Maerkisch <bmaerkisch@web.de>
* src/plot.c (main): Fix persist mode on Windows when reading
from a pipe.
See Bug #1322
2014-06-15 Akira Kakuto <kakuto@fuk.kindai.ac.jp>
* src/binary.c src/datafile.h src/syscfg.h: LFS support on Windows
for MSVC and MinGW.
See also Patch #675
2014-06-14 Ethan A Merritt <merritt@u.washington.edu>
* src/axis.h src/axis.c src/boundary.c src/plot2d.c (eval_plots):
Unlike all other axes, log scaling was being applied to the color axis
(cb) in do_plot() rather than in the caller eval_plots().
This caused "refresh" (as opposed to "replot") to fail. Move the
log-scale correction up to eval_plots() like the other axes.
Bug #1425
* src/misc.c (prepare_call): Allow parenthesized expressions as
call parameters. The value is passed as a string.
* src/command.c (exit_command): New option "exit error 'message'"
prints the message and return to the top command line, breaking out
of any loops or calls cleanly. In non-interactive mode the program
then exits.
2014-06-13 Bastian Maerkisch <bmaerkisch@web.de>
* src/qtterminal/qt_term.cpp (qt_waitforinput): Fix index error
when trying to stop thread which reads from pipe.
Bug #1426
2014-06-13 Ethan A Merritt <merritt@u.washington.edu>
* src/datafile.c (df_generate_pseudodata): Do not try to access plot
structure if we were called from fit rather than plot.
Bug #1427
2014-06-12 Christoph Bersch <usenet@bersch.net>
* term/lua.trm term/lua/gnuplot-tikz.lua:
Scale dashlength with linewidth.
2014-06-11 Ethan A Merritt <merritt@u.washington.edu>
* src/mouse.c (event_reset) src/qtterminal/QtGnuplotWindow.{h|cpp}:
Window close events from qt were not being passed through to the main
program, so "pause mouse close" did not work. Also a backgrounded
instance could hang rather than exit when the last plot window closed.
Bug #1418
* src/fit.c: Remove spurious test and error message for time data
with only 2 columns in the using spec.
Bug #1424
* man/gnuplot.1: update
2014-06-11 Mojca Miklavec <mojca.miklavec.lists@gmail.com>
* term/aquaterm.trm: Correctly support encoding CP1252.
2014-06-11 Tatsuro MATSUOKA <tmacchant3@yahoo.co.jp>
* win/gnuplot.iss: Include Qt platform DLLs in distribution package.
2014-06-10 Ethan A Merritt <merritt@u.washington.edu>
* docs/gnuplot.doc: Add a section explaining the "persist" option.
Bug #1418, #1419
* term/post.trm term/svg.trm src/qtterminal/qt_term.cpp:
Add an empirical scale factor to the dashlength*linewidth computation to
make the resulting patterns closer in total size to the built-in ones.
2014-06-10 Christoph Bersch <usenet@bersch.net>
* term/post.trm term/svg.trm: Scale dashlength with linewidth.
2014-06-09 Daniel J Sebald <daniel.sebald@ieee.org>
* src/qtterminal/QtGnuplotWidget.cpp (processEvent): Always "resize"
the initial plot to its own size. This may work around strangeness on
some systems that create the initial qt plot window with the wrong size.
Bug #1417 (forwarded from Debian) Patch #661
2014-06-09 Bastian Maerkisch <bmaerkisch@web.de>
* src/win/wgdiplus.cpp src/win/wgraph.c src/win/wgnuplib.h
term/win.trm:
Version 5 dashtypes. Custom dashtypes supported by GDI+ driver.
* src/wxterminal/wxt_gui.cpp: Also "restore" the window state on
"raise".
Bug #1389
* src/win/winmain.c (WinMain): Change type from PASCAL to CALLBACK.
* src/fit.c: Test if covariance matrix is available before saving
it to user variables.
2014-06-08 Shigeharu Takeno <shige@iee.niit.ac.jp>
* docs/gnuplot.doc win/README-Windows.txt win/README-ja.txt
docs/gnuplot-ja.doc: sync to docs version 1.891
2014-06-07 Mojca Miklavec <mojca.miklavec.lists@gmail.com>
* src/wxterminal/gp_cairo.c: Scale dashlength with linewidth, similar
to what qt does.
2014-06-04 Bastian Maerkisch <bmaerkisch@web.de>
* src/plot.c src/win/winmain.c|h term/caca.trm: Only if a wxt, caca
or windows terminal window is open, the -persist option is handled by
keeping the main input loop running. This is unfortunate but maybe the
best we can do since we are missing a process fork or detach mechanism.
This avoids a zombie process when no plot windows are open in a
session. For the qt terminal -persist works as on other platforms
since it uses a secondary process.
Bugs #1308, #1335, #1343
2014-06-03 Ethan A Merritt <merritt@u.washington.edu>
* src/graph3d.c src/show.c src/save.c docs/gnuplot.doc:
The hidden3d code processes the lines making up the plot border using
the same algorithm as it does for the plot elements. This renders
partially occluded borders correctly for actual surfaces but fails to
recognize occlusion for, e.g., 3D histograms drawn with impulses.
New keyword option "set border behind" draws the border lines before
the plot elements even for hidden3d plots.
* src/term_api.h src/wxterminal/gp_cairo.c src/wxterminal/wxt_gui.cpp:
Change the implementation of greying out inactive keybox entries in wxt
to use a textbox rather than the active area of the key entry.
Bug #1416
* src/hidden3d.c (draw_vertex): Handle p_type == PT_CHARACTER.
2014-06-02 Bastian Maerkisch <bmaerkisch@web.de>
* src/win/wgraph.c src/win/wgdiplus.cpp:
Grey out key entries when corresponding plot is toggled off.
* src/win/wgraph.c (GraphUpdateWindowPosSize) src/win/wgnuplib.h
term/win.trm (WIN_options): Immediately apply changes to window
position and size.
Bug #1400
* src/datafile.h: Revert the Windows LFS changes for now as
they seem to cause problems on some systems.
2014-06-01 Ethan A Merritt <merritt@u.washington.edu>
* src/axis.c src/gadgets.c src/misc.c src/set.c src/unset.c:
Replace magic numbers with LAYER_{BEHIND|BACK|FRONT}.
* src/graph3d.c: Remove obsolete (always true) conditional
USE_GRID_LAYERS. Minor clean up for the grid layer logic.
2014-06-01 Tatsuro MATSUOKA <tmacchant3@yahoo.co.jp>
* win/gnuplot.iss: Include gnuplot_qt.exe in installer.
Patch #689
* src/qtterminal/gnuplot_qt.cpp: Search for Qt translation files
in gnuplot's installation directory on Windows.
Patch #687
2014-06-01 Ethan A Merritt <merritt@u.washington.edu>
* src/datafile.h: Partial support for LFS on Windows. Currently
mostly useful for 64 bit builds since integers on the the gnuplot
command line are limited to 31bits otherwise.
Patch #675
2014-06-01 Bastian Maerkisch <bmaerkisch@web.de>
* config/mingw/Makefile: Target 'clean' and 'veryclean' include
Qt files, see patch #688.
* config/mingw/Makefile win/gnuplot.iss: Include RELEASE_NOTES.
Add "qt" as option as default terminal.
2014-05-30 Ethan A Merritt <merritt@u.washington.edu>
* term/post.trm term/cairo.trm: The "header" keyword for epslatex
and related terminals can introduce a string of arbitrary length.
Therefore it is not safe to try to store it in the fixed length
term_options character array.
Bug #1413
* term/gd.trm: Limit the stored length of the font so that term_options
cannot overflow.
Bug #1413
* Makefile.am RELEASE_NOTES: Include Release Notes in the distribution
package.
* FAQ.PDF: Update for version 5.
* src/gplt_x11.c:
Grey out key entries when corresponding plot is toggled off.
2014-05-29 Akira Kakuto <kakuto@fuk.kindai.ac.jp>
* term/caca.trm: Modify nominal codepage to accommodate CJK Windows.
2014-05-29 Tatsuro MATSUOKA <tmacchant3@yahoo.co.jp>
* config/mingw/Makefile: Support compilation of the qt terminal.
Patch #684
2014-05-29 Karl Ratzsch <ratzsch@uni-freiburg.de>
* docs/gnuplot.doc: Improve documentation of `update` command.
Patch #686
* src/win/wgdiplus.c src/win/wgraph.c: Change order of pointtypes to
match the sequence in other terminals (cairo, postscript, gd, svg).
Patch #681
2014-05-28 Ethan A Merritt <merritt@u.washington.edu>
* src/graph3d.c (plot3d_points): Handle pointtype PT_CHARACTER.
* src/plot3d.c: Rearrange the order of testing for plot style options
so that it is not possible to end up with uninitialized font or text
properties.
2014-05-27 Ethan A Merritt <merritt@u.washington.edu>
* src/datafile.c (df_readascii): Report status DF_UNDEFINED if a data
value evaluates to the constant "NaN", just as if we calculated it on
the fly to be e.g. 1/0.
* src/stats.c: Remove out-of-date comment that incorrectly describes
what happens in this case.
Bug #1408
2014-05-26 Ethan A Merritt <merritt@u.washington.edu>
* term/js/gnuplot_svg.js term/svg.trm:
Grey out key entries when corresponding plot is toggled off.
* src/qtterminal/QtGnuplotItems.* src/qtterminal/QtGnuplotScene.cpp:
Grey out key entries when corresponding plot is toggled off.
* src/wxterminal/wxt_gui.cpp (wxt_grey_out_key_box):
Grey out key entries when corresponding plot is toggled off.
2014-05-24 Bastian Maerkisch <bmaerkisch@web.de>
* src/wxterminal/wxt_gui.cpp (wxt_waitforinput): Do not wait for an
event when only checking for mouse events.
Bugfix
2014-05-23 Ethan A Merritt <merritt@u.washington.edu>
* src/boundary.c: A width adjustment for the length of the key title
was being applied to every column of entries in the key instead of just
once for the whole key. Apply the "set key {no}enhanced" property to
the key title as well as to the individual plot titles.
Bugfix.
2014-05-19 Ethan A Merritt <merritt@u.washington.edu>
* src/wxterminal/wxt_gui.h: Apparently wxWidgets3 (wxgtk3) threads call
into Xlib but fail to initialize X threading before doing so. Therefore
we must call XInitThreads before forking wxt threads.
Bug #1401
2014-05-19 Karl Ratzsch <ratzsch@uni-freiburg.de>
* term/emf.trm: Add point types pentagon (14) and filled pentagon (15)
2014-05-16 Ethan A Merritt <merritt@u.washington.edu>
* src/term.c (load_linetype): As documented, "set linetype cycle N"
should only affect line properties (color, width, dash), not point
properties (type, interval, size). This got lost somewhere, which
meant point types > linetype_recycle_count were never used by default.
Now they are. This means that, as intended, 'with linespoints' cycles
through (linetype_recycle_count * terminal's_max_point_type) distinct
combinations before repeating so long as those two numbers are
mutually prime. Unfortunately that's not guaranteed and is terminal-
dependent. We really need a "set pointtype cycle M" command also so
that you can choose M to be prime relative to N.
Bugfix.
* INSTALL docs/gnuplot.doc: Update description of new features.
2014-05-15 Ethan A Merritt <merritt@u.washington.edu>
* configure.in PATCHLEVEL src/version.c docs/titlepag.tex:
Bump version information to 5.0.rc1
* demo/dashtypes.dem: Avoid irrelevant warning message.
2014-05-14 Karl Ratzsch <ratzsch@uni-freiburg.de>
* term/svg.trm src/wxterminal/gp_cairo.c:
Add point types pentagon (14) and filled pentagon (15)
* src/qtterminal/QtGnuplotItems.cpp:
(EAM) Add point types pentagon (14) and filled pentagon (15)
2014-05-13 Ethan A Merritt <merritt@u.washington.edu>
* src/command.c src/tables.c src/tables.h: Remove undocumented routine
test_time(). It was never updated to handle sub-second time precision,
and in any case the functionality is now covered adequately by
"print strptime()" and "print strftime()".
* src/color.c (filled_polygon_3dcoords filled_polygon_zfixed)
src/pm3d.c (filled_color_contour_plot): The option "set pm3d at C" is
undocumented and doesn't work anyhow. Wrap the corresponding code in
#ifdef PM3D_CONTOURS . This disabled code may or may not be useful for
some future implementation of filled contours.
* term/post.trm (PS_dashtype): Always stroke the previous path before
setting a new dashtype.
2014-05-11 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* src/util.c (LOCAL_BUFFER_SIZE): New constant.
(gprintf): Use constant to identify buffer size, instead of typing
the same magic number multiple times. Insert warning about
remaining magic number.
* src/plot2d.c (get_data): Fix buffer overflow a bit more cleanly.
(compare_boxplot_factors): Insert warning about magic number.
2014-05-11 Ethan A Merritt <merritt@u.washington.edu>
* src/plot2d.c (get_data): fix buffer overflow
* src/datafile.c (f_stringcolumn): Return an empty string if asked for
stringcolumn(N) on an empty field of a *.csv file. Otherwise it would
return NULL which may cause a segfault later on.
Bugfix.
* src/datafile.c (df_readascii): If xticlabels(f(n)) returns a
non-string value then do not generate an axis tic. It used to issue
a warning about illegal string values but generated a tic anyway.
2014-05-10 Dima Kogan <dima@secretsauce.net>
* src/mouse.c (do_zoom rescale_around_mouse): Handle various conditions
that caused zooming around the current mouse position to fail.
Re-applied after tracking down conflict.
2014-05-10 Shigeharu Takeno <shige@iee.niit.ac.jp>
* docs/gnuplot.doc: various small corrections
* docs/gnuplot-ja.doc term-ja.diff: Sync translation to version 1.887
2014-05-10 Ethan A Merritt <merritt@u.washington.edu>
* term/gd.trm: Do not allow setting terminal size to 0. Bug #1398
2014-05-10 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* term/lua.trm: Ensure initialization of alpha.
* src/hidden3d.c (store_polygon): Ensure initialization of v[],
just in case somebody calls this function with an illegal
'direction' enum value.
* src/win/wgraph.c (PATTERN_BITMAP_LENGTH): Give name to magic number.
(pattern_bitmaps): Use new name.
* term/emf.trm (PATTERN_BITMAP_LENGTH): Give name to magic number.
(pattern_bitmaps): Use new name and make const.
(EMF_filled_polygon): Define pattern pointer more locally and make
it point to const. Use named constant in loop. Fix table
underrun.
* src/win/wgnuplib.c (GetInt): Add some parentheses.
* src/stats.c (statsrequest): Initialize local data structs, to
avoid warnings about printing uninitialized results.
* src/readline.c (BACKSPACE): Define as a character constant, not
some hex number.
(readline): Write TAB as character constant, not some hex number.
* src/interpol.c (gen_interp_frequency): Ensure initialization of
y_total regardless of smooth type.
* src/plot3d.c (grid_nongrid_data): Ensure initialization of
numpoints.
* src/pm3d.c (pm3d_plot): Ensure initialiation of gray.
All the following concern the same problem: Macros from <ctype.h>
cannot safely be called with arguments of type 'char' (because
that may be signed). Such values have to be cast to unsigned char
on passing.
* src/win/wtext.c (TextPutStr): See above.
* term/post.trm (PS_load_fontfile): See above.
* src/win/winmain.c (GetLanguageCode, open_printer): See above.

REVERT patch from 2014-04-26 because it broke normal zoom operations.
* src/mouse.c (do_zoom rescale_around_mouse): Handle various conditions
that caused zooming around the current mouse position to fail.
2014-05-08 Ethan A Merritt <merritt@u.washington.edu>
* src/axis.h (ACTUAL_STORE_WITH_LOG_AND_UPDATE_RANGE)
src/plot2d.c (store2d_point) src/plot3d.c (get_3ddata)
src/datafile.c (df_readascii) src/tabulate.c:
Revised handling of NaN or Inf in the input data stream. The program
used to set type=undefined for this point but left all the data fields
untouched (i.e. left them containing random garbage). Version 5 fills
in all data fields, including the one[s] containing NaN or Inf.
This means that the output from "set table" matches the input data
whereas before any line marked "u" contained garbage in the data fields.
Note: For 3D data z=NaN or z=Inf is replaced by z=0. This is needed to
avoid problems with image data. Possibly this special case should be
handled in the image code itself rather than at the input stage.
* src/plot2d.c (impulse_range_fiddling) src/plot3d.c: Don't extend
range to zero for log-scaled axes.
2014-05-06 Ethan A Merritt <merritt@u.washington.edu>
* term/emf.trm: Custom dashtype support.
* configure.in term/pdf.trm: Modify PDFlib terminal for use with
version 5 dashtypes (but no custom dashtype support). Do not build
by default.
2014-05-05 Ethan A Merritt <merritt@u.washington.edu>
* src/gp_types.h src/graphics.c (place_objects do_rectangle)
src/misc.c (lp_parse) src/save.c (save_object) src/set.c (set_obj):
Allow object borders to have a full set of line properties including
dashtype.
* docs/gnuplot.doc: Update documentation to better describe recent
changes.
* src/qtterminal/QtGnuplotScene.cpp: Always use a solid line to draw
point symbols, even if the current linetype has a dash pattern.
* term/cairo.trm term/canvas.trm term/post.trm term/svg.trm term/wxt.trm
term/x11.trm src/term.c: Terminals that have been upgraded to version 5
dash handling should ignore the "dashed/solid" terminal setting.
* src/plot2d.c (impulse_range_fiddling) src/plot3d.c: Autoscaled plots
"with impulses" should include y=0 (z=0 in 3D) unless log-scaled.
2014-05-05 Tatsuro MATSUOKA <tmacchant3@yahoo.co.jp>
* src/qtterminal/po/qtgnuplot_ja.ts: Update translations
2014-05-03 Ethan A Merritt <merritt@u.washington.edu>
* src/qtterminal/po/qtgnuplot_ja.ts: Update translations.
2014-05-01 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
* config/mingw/Makefile (LDFLAGS2): Add auto-import flag.
($(TARGET)): Add icon files and Makefile as dependencies.
* config/config.mgw, config/config.cyg: The set of used /
available configuration macros has changed across the past several
years.
* src/stdfn.h (sgn): Fix parenthesization of macro.
(PATH_MAX): CLang compiler on Cygwin needs a silly little tweak.
* src/graphics.c (samesign): Improve parenthesization a bit.
2014-05-01 Ethan A Merritt <merritt@u.washington.edu>
* demo/gantt.dem demo/html/*: Add Gantt chart to demo collection.
Add dashtypes to demo collection.
* src/show.c: Show "fixed" property of arrow style.
2014-04-29 Ethan A Merritt <merritt@u.washington.edu>
* src/datafile.c (f_timecolumn): Replace the old 1-parameter function
timecolumn(col) with a 2-parameter timecolumn(col,"timeformat"). The
old version had no way to handle time data that didn't correspond to
a coordinate on a plot axis in time format (e.g. set xdata time).
It would segfault if the function appeared in a using spec slot >= 2.
Now we require an explicit format, so data input is dissociated from
any particular axis or time setting.
Bug #1394
* src/gplt_x11.c term/x11.trm term/xlib.trm:
Custom dashtype support for X11.
2014-04-28 Dima Kogan <dima@secretsauce.net>
* src/mouse.c src/mouse.h src/set.c src/show.c docs/gnuplot.doc:
Remove the distinction between "coordinate format echoed to the screen
during mousing" and "coordinate format saved to the clipboard on click".
This removes the default bindings for hotkeys 3 and 4.
