John, Dmitri,

Thanks for the help; that got me going in the right direction. I elected to
go the legend('off') route, but that led me to some other problems.

When I use legend.m to actually write a legend with my own text strings, the
graw and gset warnings reappear. In looking at the legend.m routine that
comes with octave-forge-2004.11.16, it has a dozen or so mentions of gset
and graw that are apparently triggering the warnings.

I think I know how to rewrite legend.m to use __gnuplot_set__ in place of
gset. I've already done that successfully in another routine, my local
version of figure.m that sets font and font size. Is __gnuplot_set__ the
correct approach, or is there a better, more forward looking way?

In legend.m graw appears as

  tmpfilename=tmpnam;
  command=["save \"",tmpfilename,"\"\n"];
  graw(command);

and as

  new_plot = [new_plot, "\n"];
  graw(new_plot);

What is the correct replacement for this usage of graw? __gnuplot_set__ does
not seem appropriate here.

If I get something working, I'll send it to the bug list for possible
inclusion. Alternatively, does someone else have a patched version of
legend.m already available?

Joe
