Module documentation for 0.5.7

Used by 2 packages in nightly-2026-01-08(full list with versions):
learn-physics, tlynx

This is a wrapper to gnuplot which lets you create 2D and 3D plots.

Start a simple session with cabal repl. If not already loaded, call :module Graphics.Gnuplot.Simple in order to load Graphics.Gnuplot.Simple which is ready for use in GHCi. It does not address all fancy gnuplot features in order to stay simple. For more sophisticated plots, especially batch generated graphics, I recommend Graphics.Gnuplot.Advanced. This module contains also an overview of the hierarchy of objects.

Examples for using this interface can be found in the Demo module. In order to compile this and install an example data file, use the Cabal flag buildExamples:

$ cabal install -fbuildExamples gnuplot

With the Cabal flags executePipe and executeShell you can switch to more convenient but probably less portable ways of feeding gnuplot with a script.

Alternative packages: plot, HPlot, Chart, textPlot, easyplot

0.5.5:

  • Gnuplot.Utility.quote bugfix: Do not escape printable non-ASCII characters because gnuplot has no universal escaping support for Unicode codepoints.
