Several options may be set in the `postscript` driver.
Syntax:
set terminal postscript {<mode>} {enhanced | noenhanced}
{color | monochrome} {solid | dashed}
{<duplexing>}
{"<fontname>"} {<fontsize>}
where <mode> is `landscape`, `portrait`, `eps` or `default`;
`solid` (Note:solid ) draws all plots with solid lines, overriding any
dashed patterns; <duplexing> is `defaultplex`, `simplex` or `duplex`
("duplexing" in PostScript is the ability of the printer to print on both
sides of the same page---don't set this if your printer can't do it);
`enhanced` activates the "enhanced PostScript" features (subscripts,
superscripts and mixed fonts); `"<fontname>"` is the name of a valid
PostScript font; and `<fontsize>` is the size of the font in PostScript
points.
`default` mode sets all options to their defaults: `landscape`, `monochrome`,
`dashed`, `defaultplex`, `noenhanced`, "Helvetica" and 14pt.
Default size of a PostScript plot is 10 inches wide and 7 inches high.
`eps` mode generates EPS (Encapsulated PostScript) output, which is just
regular PostScript with some additional lines that allow the file to be
imported into a variety of other applications. (The added lines are
PostScript comment lines, so the file may still be printed by itself.) To
get EPS output, use the `eps` mode and make only one plot per file. In `eps`
mode the whole plot, including the fonts, is reduced to half of the default
size.
Examples:
set terminal postscript default # old postscript
set terminal postscript enhanced # old enhpost
set terminal postscript landscape 22 # old psbig
set terminal postscript eps 14 # old epsf1
set terminal postscript eps 22 # old epsf2
set size 0.7,1.4; set term post portrait color "Times-Roman" 14
Linewidths and pointsizes may be changed with `set linestyle`
(Note:linestyle ).
The `postscript` driver supports about 70 distinct pointtypes, selectable
through the `pointtype` option on `plot` (Note:plot ) and set linestyle.
Several possibly useful files about `gnuplot` (Note:gnuplot )'s PostScript
are included in the /docs/ps subdirectory of the `gnuplot` distribution and at
the distribution sites. These are "ps_symbols.gpi" (a `gnuplot` command file
that, when executed, creates the file "ps_symbols.ps" which shows all the
symbols available through the `postscript` terminal), "ps_guide.ps" (a
PostScript file that contains a summary of the enhanced syntax and a page
showing what the octal codes produce with text and symbol fonts) and
"ps_file.doc" (a text file that contains a discussion of the organization of a
PostScript file written by `gnuplot`).
A PostScript file is editable, so once `gnuplot` has created one, you are
free to modify it to your heart's desire. See the "editing postscript"
section for some hints.
