== More complex example ==
(I need to change this example to highlight other aspects. Metapost is kind-of-obsolete since ConTeXt terminal was derived from it and produces superior results. But the example below should still be valid.)
<texcode>
\usemodule[gnuplot]
\setupGNUPLOT[terminal=mptikz,option=color]% terminal=mp if you only have an old gnuplot at hand
% general settings for the whole document
# (0.0, 0.5, 1.0, 1.5, ...) instead of
# (0, 0.5, 1, 1.5, ...)
set format y '\%.1f'
\stopGNUPLOTinclusions
