What's new in 3.6 ?
See docs/old/ChangeLog.old and ChangeLog for a list of changes
As always, there are outstanding contributed patches
that I haven't yet installed (sorry), and half-promises for features
that I've not had a chance to fulfill.
in this release
try to improve (and not break too badly) portability
multiple X11 windows have number in window title, and active window
has crosshair cursor
in 315
suppress ! after a ! command in interactive mode
address polar mode
314
misc bug fixes
310
HBB's hidden3d fix
latest gnuplot.doc and term/*.trm help sections
configure --with-gnu-readline[=path]
in 309
sorry Roger ; os2 keeps on improving, but I forget to announce it
{and often incorporate it !}
relative errors displayed in fit
in 306
histeps style
LINE WIDTH PATCH ! {but many structures passed by value ?}
tolerate missing closing backquote at end of line
no limit on output filename
set key samplelen / spacing
plot ... axis alias for plot ... axes
Thomas Koenig's postscript test for reencoding on the fly [at last]
multiplot clear for djsvga
size option on gif driver
in 300
FINALLY moved the axes syntax over to plot ... axes x1y1 ...
3d fitting ; FIT_INDEX no longer supported/needed (see fit.dem)
added data columns -1 for line and -2 for index, for 3d fit
had another go at the VPATH stuff for configure / make
in 297
back out unwanted feature of basing tics on relative size/font
add financebars / candlesticks - size controlled by set bar
plot 'file' using 0:1 gives x=0,1,... as gnuplot 3.5
optional keyword 'font' in set xlabel 'text' dx,dy [font] "font,size"
fix undefined points in splines
in 293/294
ICCCM export of the x-window (allow paste into compliant apps ie NTRIGUE)
print "string", expression, "string", ...
set size square has been generalised to
set size { square | ratio <r> | noratio }
where <r> is an aspect ratio of height / width
(at last) Hans-Bernhard Br"oker's changes, including fit fix and
new hidden line removal routine
plot line is commited to replot line at last possible moment, so
that typos in complex plot do not ruin everything
time routines separated into time.c - option to use system time
routines instead of the gnuplot ones. Undocumented command
testtime 'format' 'string' to assist testing of time routines
small changes to the terminal handling : hide details in term.c
new shared makefile strategy : makefile.all
in 273

first attempt at timecolumn() and tm_sec() family of functions
splot 'file' matrix
in 248 (?)
try *again* to fix the postscript bounding box
ALL TERMINALS UPDATED (thanks Stefan !)
Continue to move help out of gnuplot.doc into terminal driver files (thanks Joerg)
address problems with splines in log scales - NOTE that we take logs
and then fit splines
%T in gprintf prints as %d not %f hence no trailing .0000
set locale only affects LC_TIME (for the moment ?)
make start optional in series tics, ie accept
set [xyz]tics {start,}step{,end}
also, if start or end not specified, treat as computed, and autoextend
plot to a multiple of tics
in 242
allow negative ticslevel
geometric series tics for logscale
enhanced sprintf format for tics - extra format characters available
%x %o %e %f %g %t %T %l %L %s %S %c
take plot size and driver into account when choosing tics
accept x1y2 etc in place of first/second
extra line in boxed key
x2 label
fonts for label
strftime format for 'set time'
more timeseries patches
set locale
try to fix postscript bounding box
in 224
set clabel ['format']
pstexdriver
set encoding
enhpost moved into post.trm
index a:b:c for splot
in 194
multiplot for splot
in 188
os9 port
set xrange [] reverse writeback
allow mix of co-ordinate systems within an arrow/label posn
initial multiplot support
- doesn't yet check that terminal is capable, but there is a
flags field added to the terminal entry to tell gnuplot about this.
also, suspend() / resume() entry points which are to be called
between plots of a multiplot.
in 178
arbitrary length/number of columns in datafile
accept double/quad-precision fortran numbers (1.23{dDqQ}4)
- but not in scanf format string
undefined fit parameters start at 1 rather than 1e-30
- more chance of convergence / less change of unitary matrix
WIN32 / Win-NT support
table output can be read back in for data splot
- hence gnuplot can be used to dgrid a datafile and write it out
set missing 'string'
- nominate a token as standing for missing values in datafile
- not yet added to documentation
updates to time-series stuff (so it doesn't break at 2000)
- except it has become horribly non-portable :-(
split graph3d.c into util3d.c and hidden3d.c
in 166
set bar <size>
- a number rather than just small or large
allow different linetypes for grid at major and minor tics
a few more set no* commands for consistency.
initial go at implementing tic mirrors and axes for splot
- no ztic axis yet (or no zzeroaxis)
- tics on axes are not hidden by surface
attempt to make sin(x) behave as expected when set angle degrees
- gives answers if x is complex, but I dont know if they are correct
- acos(cos(x)) seems to give x, so at least its consistent
- fix a bug which made acos(cos({0,1})) undefined
new grass.trm
in release 162/164
set size [{no}square] x,y - tries to plot with aspect ratio 1
- seems to work great for postscript
- please check with your favourite driver
- uses relative sizes of tics to determine required size.
posn for key, labels and arrows can be in one of 4 co-ordinate systems
- first_axes (default)
- second_axes (for plot..second)
- graph (0,0 -> 1,1 = plotting area)
- screen (0,0 -> 1,1 = whole screen)
- arrows needn't have endpoints in same co-ords. see help set label
via is now a required keyword for fit
- fit f(x) 'file' ... via { 'file' | a,b,... }
- this is to avoid confusing 'file' with 'using-format-string'
win32 and 16-bit dos fixes
- I can compile with tc++, but get an overlay error at runtime.
new set of documentation programs (I haven't tried them)
various tweaks to makefile
changes to pslatex
- substitute .ps at _last_ . in filename
- accept font size of enclosing document as an option.
- dont forget to close aux file
in release 151
linux security patch
can specify font for labels, etc (postscript only ? - I haven't tried this)
can specify linetype to draw grid / zeroaxes / arrows
emx terminal driver
first attempt at pipes for VMS and vector style - needs more work
l/b/r/t-margin in place of xmargin - more control over size of margins
incompatible changes to polar mode:
- t is now the dummy variable, so x is width of plot as expected
- tics are not automatically on axes - set {xy}tics axis nomirror
- grid is not automatically polar - set grid x [mx] polar [angle]
- no numbers on grid - they were always in degrees
second axes
- x2 and y2 are an independent pair of axes, but they inherit
ranges from x and y if no second data
- there can be problems with this, actually - if x2tics are not
shown, x2range is not autoextended to whole number of tics, so
same data might not have same range.
- set x2tics/y2tics/x2label/y2label
- set [no]log x2 / y2
- plot [first,] f(x), 'file', ..., second, g(x), ...
- get specify grid at any/all of x,y,x2,y2
- see electron.dem
set border <mask> - 12 bit binary number selects 12 sides of cube around splot
can specify grid z, to get a grid on back wall of splot
set mxtics [<interval>|default] | set nomxtics
- set mxtics gives auto for logscale, fixed for linear
binary, index and every keywords to datafiles.
- every also works with binary files
can use '-' as datafile for inline data (ends at line with e)
can use '' to mean reuse previous file
splot and fit now use datafile module
- FIT_SKIP no longer supported - use fit f(x) 'file' every n
can limit fit range using fit [variable=min:max] f(variable) ...
set ticscale <major> [<minor>]
surface is clipped with no hidden line removal
- still to do contour and hidden-line surface
set {x|y|x2|y2} [axis|border] [no]mirror
- can put tics on border or axes
- mirror controls mirroring of tics on opposite axis
- no longer coupled to set tics out setiing.
No longer need to specify parametric mode for 3-column data files.
ranges automatically extended to whole number of tic intervals
- doesn't always manage to drop vertical from surface to corner of base
- workaround is either specify range or use set border
patchlevel 140
--------------
I've probably missed a lot of features since I'm so used to them.
Plus I never bothered with 3.5 so some of these may have been there.
some of these may have made it into the documentation
Here goes:
fit f(x) 'file' via ...
read and plot time data (timedat.dem)
set key [top|bottom|under] [left|right|out] [reverse] [box [<linetype>]]
set key title 'text'
Processing of escape sequences in "strings" but not 'strings'
- TeX users in particular advised to use ''
Multiline labels, etc, using "first\nsecond"
enhpost driver
call command (load with parameters)
x error bars. splines. boxes. [some may have been in 3.5]
pipes for amiga
the using patch plot 'file' using spec:spec:...
- spec is either column number or (expression in $1, $2, ...)
new pslatex driver with postscript to aux file.
set pointsize <scale factor> on some terminals
doubles in plot...using format string - %lf
unlimited input line length and expression (action) table
minor tic-marks (like logscale but also for linear)
- also set grid [mx|my]
that's all I can think of for the moment...
