Thanks, Mario. I tried it in one system without using any root privilege and it seemed to have worked for your simple example, with the known issue involving dot_dash line type.

A little annoyance is that it seems the load function only understands complete absolute paths.
For example??load("$HOME/maxima/draw.lisp") or load("~/maxima/draw.lisp") would not work ( same internally when draw itself invokes load on lines 34, 35).?Relative paths (../ , ?./, etc) seem NOT to work either.

The alias $HOME or ~ or the relative paths would be preferable, particularly w.r.t. the line 34/35 modifications, because then one modified copy of draw would work on multiple systems (provided the pertinent files are placed in the right place, such as on $HOME/maxima in this example).?Not a big deal, just a little annoyance.

I suppose that user_preamble= "xxxxxxxxxx" is another approach that may perhaps be useful if not in this specific case, in similar cases, in which one may want to issue direct commands to gnuplot to achieve a functionality not provided explicitly by draw.

Best,

Virgil
