166 gnuplot 4.3 77 TERMINAL
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,c), ’]{’, 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. See also the
documentation for the pslatex (p. 189) terminal driver. To create multiline labels, use \shortstack,
for example
set ylabel ’[r]{\shortstack{first line \\ second line}}’
The back option of set label commands is handled slightly different than in other terminals. Labels
using ’back’ are printed behind all other elements of the plot while labels using ’front’ are printed above
everything else.
The driver produces two different files, one for the eps part of the figure and one for the LaTeX part.
The name of the LaTeX file is taken from the set output command. The name of the eps file is derived
by replacing the file extension (normally .tex) with .eps instead. There is no LaTeX output if no output
file is given! Remember to close the output file before next plot unless in multiplot mode.
In your LaTeX documents use ’\input{filename}’ to include the figure. The .eps file is included by the
command \includegraphics{...}, so you must also include \usepackage{graphicx} in the LaTeX preamble.
If you want to use coloured text (option textcolour) you also have to include \usepackage{color} in the
LaTeX preamble.
Pdf files can be made from the eps file using ’epstopdf’. If the graphics package is properly configured,
the LaTeX files can also be processed by pdflatex without changes, using the pdf files instead of the
eps files. The behaviour concerning font selection depends on the header mode. In all cases, the given
font size is used for the calculation of proper spacing. When not using the standalone mode the actual
LaTeX font and font size at the point of inclusion is taken, so use LaTeX commands for changing fonts.
If you use e.g. 12pt as font size for your LaTeX document, use ’"" 12’ as options. The font name is
ignored. If using standalone the given font and font size are used, see below for a detailed description.
If text is printed coloured is controlled by the TeX booleans \ifGPcolor and \ifGPblacktext. Only if
\ifGPcolor is true and \ifGPblacktext is false, text is printed coloured. You may either change them in
the generated TeX file or provide them globally in your TeX file, for example by using
\newif\ifGPblacktext
\GPblacktexttrue
in the preamble of your document. The local assignment is only done if no global value is given.
When using the epslatex terminal give the name of the TeX file in the set output command including
the file extension (normally ".tex"). The eps filename is generated by replacing the extension by ".eps".
If using the standalone mode a complete LaTeX header is added to the LaTeX file; and "-inc" is added
to the filename of the eps file. The standalone mode generates a TeX file that produces output with
the correct size when using dvips, pdfTeX, or VTeX. The default, input, generates a file that has to be
included into a LaTeX document using the \input command.
If a font other than "" or "default" is given it is interpreted as LaTeX font name. It contains
up to three parts, separated by a comma: ’fontname,fontseries,fontshape’. If the default fontshape
or fontseries are requested, they can be omitted. Thus, the real syntax for the fontname is ’[fontname][,fontseries][,fontshape]’.
The naming convention for all parts is given by the LaTeX font scheme.
The fontname is 3 to 4 characters long and is built as follows: One character for the font vendor, two
characters for the name of the font, and optionally one additional character for special fonts, e.g., ’j’ for
fonts with old-style numerals or ’x’ for expert fonts. The names of many fonts is described in
http://www.tug.org/fontname/fontname.pdf
For example, ’cmr’ stands for Computer Modern Roman, ’ptm’ for Times-Roman, and ’phv’ for Helvetica.
The font series denotes the thickness of the glyphs, in most cases ’m’ for normal ("medium") and ’bx’
or ’b’ for bold fonts. The font shape is ’n’ for upright, ’it’ for italics, ’sl’ for slanted, or ’sc’ for small
caps, in general. Some fonts may provide different font series or shapes.
Examples:
Use Times-Roman boldface (with the same shape as in the surrounding text):
set terminal epslatex ’ptm,bx’
