My advice is to login via ssh -X. But if you are seeing plot2d output,
probably you already solved that problem.

Hmm. My first guess is that the Gnuplot output file generated by
draw2d is invalid or something. By default draw2d generates a
couple of output files, maxout.gnuplot and data.gnuplot, in the
directory named by the global variable maxima_tempdir.
cd to that directory and try running Gnuplot from the shell prompt;
perhaps this will do: gnuplot -persist maxout.gnuplot
If that doesn't display anything, there's a bug in draw2d.
Otherwise, I'm really puzzled.
Note that plot2d generates files of the same names, so try
the gnuplot command only after calling draw2d.
