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
