- What's new in 3.6 ?
-
- Still to do
- someone has contributed a new hidden-line-removal
- '-' as load filename / command-line param
- terminals are no longer allowed to do their own scaling
- break up some of the drivers (eg epson and family) into their
- own files. *maybe* we can provide libraries of generic routines
- (particularly tex) which can be used by all interested drivers,
- and because they are a library, they are linked only if
- any relevant drivers are installed. bitmap.c could also be
- linked in this way.
- Now that all drivers are new format, do we need to explore separate
- compilation of the drivers into their own .obj files for DOS ?
-
-
- Plus quite a few contributed patches that I haven't yet installed (sorry)
-
- in this release
- 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...
