Andrej, thank you for the tip.
Unfortunately, there appears to be some further problem. I have set
gnuplot_command, but maxima spits out an error from gnuplot when I use
draw2d.
When I load the 'maxout.gnuplot' file directly into the
correct gnuplot (v4.2.4), the file is executed without error.

Leo.
