Per,

Not there yet, but we're making progress. I created the script gnuplot_aqua
and placed it in /usr/local/bin where the gnuplot-4.0 executable also
resides (I have two gnuplots: gnuplot-4.0 in /usr/local/bin and gnuplot-4.1
as /Tools/gnuplot-4.1/bin/gnuplot. I control which is used with a gnuplot
symlink.)

I did a sudo chmod +x gnuplot_aqua in /usr/local/bin and checked to make
sure I had x in the permissions. Then I started a new terminal shell, did an
export GNUTERM=gnuplot_aqua, and started octave-2.9.8.

When I tried plot(rand(1,10)); in octave I got an error:  "Unknown or
ambiguous terminal name 'gnuplot_aqua'" and no plot appeared.

So I exited octave, and did a gnuplot_aqua < gnuspect.inp, where
gnuspect.inp is a working gnuplot script. I got the same error message,
followed by the correct plot, but with Figure 1 as the title. gnuplot_aqua
did successfully invoke gnuplot-4.1, but did not change the title.

My fear is that the octave plot process proceeds in several steps, i. e., it
opens a new plot stream with gnuplot -title ... , then follows with other
plot instructions before finally closing the plot stream with a final set of
plot instructions. There are two new replacement routines for gset called
__gnuplot_raw__ and __gnuplot_set__ that allow a knowledgeable user to pass
instructions (font, line type and width, etc.) to gnuplot while the plot is
being set. 

I don't fully understand your script syntax, but I assume you are trying to
capture the title as it is passed to gnuplot.

That could lead us back to just placing a set term aqua somewhere in the
existing plot structure.

I hope I'm clear and followed your instructions correctly. Just let me know
if I need to try some other things.
