Gnuplot is a portable command-line driven utility for function plotting for many platforms.
To make the examples on this page work, you need Gnuplot 4.6.0 or later (or self-compiled binary).
Contents
Minimal Example
\usemodule[gnuplot] % write a script for gnuplot \startGNUPLOTscript[sin] plot sin(x) \stopGNUPLOTscript % include the resulting graphic into the document \useGNUPLOTgraphic[sin]
Calling gnuplot to create the graphic and postprocessing should happen automatically.
Requirements
- Gnuplot module
- in TeX Live you need to have
context-gnuplot
installed, in ConTeXt Standalone you can install it with--modules=t-gnuplot
switch
- in TeX Live you need to have
- Gnuplot has to be installed (and in your PATH)
- On most Linux installations this is probably already the case. On Windows gnuplot.exe is usually also shipped and you need to make sure that it is in PATH. In case that the binary has a different name, you could create a file
gnuplot.bat
with something like:
"C:\Program Files\gnuplot\bin\wgnupl32.exe" %*
- (if that was the binary name) and put that file to a "visible place" (has to be found in PATH). Please note: if calling
gnuplot
from cmd works for you, there is no need to do anything extra.
- Write18 has to be enabled
To use the ConTeXt terminal (recommended)
Windows
You can fetch binaries from sourceforge (released versions) or from Tatsuro Matsuoka (latest cvs version).
Unix or Mac
The easiest way is to use version 4.6.0 or later shipped by your distribution. If that version is too old, you need to compile your own.
If you want to use the version from trunk:
# unofficial; you can also use official cvs git clone git://github.com/gnuplot/gnuplot.git ./prepare ./configure make make install
I use ./configure --prefix=$PWD/inst
to avoid cluttering the system and install gnuplot to my personal directory. You can use other flags to configure for a different choice of GUI terminals.
If you want to use the released version, get it from sourceforge and do the same, just skip the ./prepare
.
The latest version of context terminal is available at http://github.com/mojca/gnuplot/raw/master/term/context.trm.
Feel free to contact Mojca in case of problems.
Creating stand-alone, whole-page plots
Here's an example of how to make a stand-alone ConTeXt document with one plot per page:
set term context standalone size 15cm,10cm header '\usetypescript[iwona]' font 'iwona,ss' 10dd set output 'example.tex' plot ...
More complex example
\usemodule[gnuplot] \setupGNUPLOT[terminal=tikz,option=color] % terminal=mp if you only have an old gnuplot at hand % general settings for the whole document \startGNUPLOTinclusions # you may use TeX commands to format the titles and axes set title '\bf Trigonometry' set xlabel '$x$' set ylabel '$y$' # to prevent uneven numbering: will result in # (0.0, 0.5, 1.0, 1.5, ...) instead of # (0, 0.5, 1, 1.5, ...) set format y '%.1f' \stopGNUPLOTinclusions \startGNUPLOTscript[tan] plot tan(x) t '$\tan(x)$' \stopGNUPLOTscript \startGNUPLOTscript[sin] plot 4*sin(x)+x t '$4\sin(x)+x$', x t '$x$' lt 3 \stopGNUPLOTscript \useGNUPLOTgraphic[tan] \useGNUPLOTgraphic[sin][width=10cm]
Using other terminals
(Needs a revision.)
Gnuplot support output in different formats with, for example
set terminal mp color solid
will output a metapost document with colors and without dashed lines. After some appropriate preprocessing (with MPtoPDF for this particular case) this file can be included in PDF documents.
You can specify the terminal with
\setupGNUPLOT[terminal=mp,options=color solid]
terminal=
is mandatory since that't the only way to tell ConTeXt how to preprocess the file.options=
is optional and is appended to the end ofset terminal [terminal name]
. You can also override it by saying
\startGNUPLOTinclusions set terminal mp color solid \stopGNUPLOTinclusions
But you have to be careful that you don't set any other terminal with output=
then.
Currently supported terminals are (attention: links not from the latest documentation):
- mp/metapost: uses MPtoPDF to convert images to pdf, but the context terminal should replace it
- ps/postscript: most advanced in the number of supported features
- png (1),png (2): outputs bitmap images (no preprocessing needed)
- pdf (old),pdf (new): outputs PDF directly for (no preprocessing needed), but is usually not available in most binaries of gnuplot
- context:

History
I (Mojca Miklavec) probably mentioned long time ago that I would like to have (or write?) support for Gnuplot inside ConTeXt, but I had no knowledge to do that. Peter Münster posted the very first module for gnuplut support on the mailing list [1], but that version only worked with bash. In the days to follow Hans Hagen has written a new module (based on my numerous "possible and impossible" requests) and Taco additionally provided some bugfixes and minor changes.
The module provides an option to select the most appropriate/suitable driver according to the user's choice (metapost, png, pdf, postscript were the firs ones to be supported). Hans was wondering why there was no context terminal. I took over it's development, the code is almost finished by now, but I guess that Hans now regrets that question already.
He had to invest quite some time into fixing buggy inclusion of text into graphics using textext
(if nothing else, he had to read and reply to all the mails [complaints] that me and Taco sent him), just to lead to the conclusion that textext
was useless for graphics produced by Gnuplot: too slow and TeX ran out of memory after 10 minutes while processing approximately the 13th plot. After that the new marvellous \sometxt
command was born.
I'm currently sticking tiny pieces together in the way I want the module to work. Hans could probably finish the same work that costs me a few days in a few minutes, but after dropping me a bone, he decided to leave me the joy of diving into ConTeXt internals and to let me figure out how to program in ConTeXt by myself. So I still keep spamming the mailing list with numerous questions and both Taco and Hans - without whom implementing the module would be impossible - keep answering.
