This package look interesting, but is there a clear documentation on
it? The only one I have been able to found is
http://www.telefonica.net/web2/biomates/maxima/gpdraw/

There are examples but no real description of the commands. By
the way, reading the gnuplot manual I have been able to achieve (some
part) of what I want.
