Many thanks for the quick fix Hans, I have tried the lmtx inclusions as well, very nice indeed (and added it to the wiki)! Kind Regards, Adam Reviczky On Mon, Jul 13, 2020 at 10:38 PM Hans Hagen wrote:

Hi,

Using the minimal example from the contextgarden for gnuplot (https://wiki.contextgarden.net/Gnuplot) I am getting the following error message:

Does the gnuplot module need adjustments? No, i messed up something ... will be fixed tomorrow

Do you have lmtx installed? It has nicer gnuplot support:

m-gnuplot-demo.gp :

------------------------------------------------ set format xy "$%g$"

set title 'This is a plot of $y=\\sin(x)$' set xlabel 'This is the $x$ axis' set ylabel 'This is the $y$ axis'

plot [0:6.28] [0:1] sin(x) ------------------------------------------------

Can be included with:

\starttext

\externalfigure[m-gnuplot-demo.gp][conversion=svg,width=4cm]

\externalfigure[m-gnuplot-demo.gp][conversion=svg,width=8cm]

\stoptext
