190 gnuplot 4.3 77 TERMINAL
in the postscript output: The color component functions are sampled at points and all points
are removed from this gradient which can be removed without changing the resulting colors by more than
. For almost every useful palette you may savely leave the defaults of =2000
and =0.003 untouched.
The default size for postscript output is 10 inches x 7 inches. The default for eps output is 5 x 3.5 inches.
The size option changes this to whatever the user requests. By default the X and Y sizes are taken to
be in inches, but other units are possibly (currently only cm). The BoundingBox of the plot is correctly
adjusted to contain the resized image. Screen coordinates always run from 0.0 to 1.0 along the full
length of the plot edges as specified by the size option. NB: this is a change from the previously
recommended method of using the set size command prior to setting the terminal type.
The old method left the BoundingBox unchanged and screen coordinates did not correspond to the
actual limits of the plot.
if rotate is specified, the y-axis label is rotated. is the size (in pts) of the desired font.
If auxfile is specified, it directs the driver to put the PostScript commands into an auxiliary file instead
of directly into the LaTeX file. This is useful if your pictures are large enough that dvips cannot handle
them. The name of the auxiliary PostScript file is derived from the name of the TeX file given on the
set output command; it is determined by replacing the trailing .tex (actually just the final extent in
the file name) with .ps in the output file name, or, if the TeX file has no extension, .ps is appended.
The .ps is included into the .tex file by a \special{psfile=...} command. Remember to close the output
file before next plot unless in multiplot mode.
Gnuplot versions prior version 4.1 have generated plots of the size 5 x 3 inches using the ps(la)tex
terminal while the current version generates 5 x 3.5 inches to be consistent with the postscript eps
terminal. In addition, the character width is now estimated to be 60% of the font size while the old
epslatex terminal used 50%. To reach the old format specify the option oldstyle.
The pslatex driver offers a special way of controlling text positioning: (a) If any text string begins with
’{’, you also need to include a ’}’ at the end of the text, and the whole text will be centered both
horizontally and vertically by LaTeX. (b) If the text string begins with ’[’, you need to continue it with:
a position specification (up to two out of t,b,l,r), ’]{’, the text itself, and finally, ’}’. The text itself may
be anything LaTeX can typeset as an LR-box. \rule{}{}’s may help for best positioning.
The options not described here are identical to the Postscript terminal. Look there if you want to
know what they do.
Examples:
set term pslatex monochrome dashed rotate
To write the PostScript commands into the file "foo.ps":
set term pslatex auxfile
set output "foo.tex"; plot ...; set output
# set to defaults
About label positioning: Use gnuplot defaults (mostly sensible, but sometimes not really best):
set title ’\LaTeX\ -- $ \gamma $’
Force centering both horizontally and vertically:
set label ’{\LaTeX\ -- $ \gamma $}’ at 0,0
Specify own positioning (top here):
set xlabel ’[t]{\LaTeX\ -- $ \gamma $}’
The other label – account for long ticlabels:
set ylabel ’[r]{\LaTeX\ -- $ \gamma $\rule{7mm}{0pt}}’
Linewidths and pointsizes may be changed with set style line.
77.55 Pstricks
The pstricks driver is intended for use with the "pstricks.sty" macro package for LaTeX. It is an
alternative to the eepic and latex drivers. You need "pstricks.sty", and, of course, a printer that
understands PostScript, or a converter such as Ghostscript.
