77 TERMINAL gnuplot 4.3 189
If the font "CMEX10" is embedded (file "cmex10.pfb") gnuplot defines the additional font "CMEX10-
Baseline". It is shifted vertically in order to fit better to the other glyphs (CMEX10 has its baseline at
the top of the symbols).
77.53.4 Postscript prologue
Each PostScript output file includes a %%Prolog section and possibly some additional user-defined
sections containing, for example, character encodings. These sections are copied from a set of PostScript
prologue files which are either compiled in the gnuplot executable or stored elsewhere on your computer.
This behaviour and the default directory where these files live are controlled at the time gnuplot is built.
However, you can control this either by defining an environment variable GNUPLOT PS DIR or by
using the gnuplot command set loadpath. See set loadpath (p. 111).
77.54 Pslatex and pstex
The pslatex driver generates output for further processing by LaTeX, while the pstex driver generates
output for further processing by TeX. pslatex uses \specials understandable by dvips and xdvi. Figures
generated by pstex can be included in any plain-based format (including LaTeX).
Syntax:
set terminal [pslatex | pstex] {default}
set terminal [pslatex | pstex]
{rotate | norotate}
{oldstyle | newstyle}
{auxfile | noauxfile}
{level1 | leveldefault}
{color | colour | monochrome}
{solid | dashed}
{dashlength | dl }
{linewidth | lw }
{rounded | butt}
{palfuncparam {,}}
{size {unit},{unit}}
{}
If you see the error message
"Can’t find PostScript prologue file ... "
Please see and follow the instructions in postscript prologue (p. 189).
The option color enables color, while monochrome prefers black and white drawing elements. Further,
monochrome uses gray palette but it does not change color of objects specified with an explicit
colorspec. solid draws all plots with solid lines, overriding any dashed patterns. dashlength or dl
scales the length of the dashed-line segments by , which is a floating-point number greater than
zero. linewidth or lw scales all linewidths by .
By default the generated PostScript code uses language features that were introduced in PostScript Level
2, notably filters and pattern-fill of irregular objects such as filledcurves. PostScript Level 2 features are
conditionally protected so that PostScript Level 1 interpreters do not issue errors but, rather, display
a message or a PostScript Level 1 approximation. The level1 option substitutes PostScript Level 1
approximations of these features and uses no PostScript Level 2 code. This may be required by some
old printers and old versions of Adobe Illustrator. The flag level1 can be toggled later by editing a
single line in the PostScript output file to force PostScript Level 1 interpretation. In the case of files
containing level 2 code, the above features will not appear or will be replaced by a note when this flag is
set or when the interpreting program does not indicate that it understands level 2 PostScript or higher.
rounded sets line caps and line joins to be rounded; butt is the default, butt caps and mitered joins;
palfuncparam controls how set palette functions are encoded as gradients in the output. Analytic
color component functions (set via set palette functions) are encoded as linear interpolated gradients
