John,

Without the addition of __gnuplot_set__ and __gnuplot_raw__ which appeared
recently to eventually replace gset, you will have a difficult time talking
directly to gnuplot, which is required to do what you want.

My suggestion would be to replace your octave-2.1.46 with the octave-2.1.71
and octave-forge from http://hpc.sourceforge.net. Follow the instructions on
the site for a relatively simple installation.

Then, if you haven't already, get and use the .dmg installers for
gnuplot-4.0 and AquaTerm-1.0 from the Apple download site and
http://aquaterm.sourceforge.net.

I still run OS X 10.3.9 and built octave-2.1.72 from source with it. I won't
upgrade to Tiger until I'm sure Apple has 10.4.x under control for open
source software, which should be soon. I guess I have the same fear of
breaking working programs that you do, but I'm a bit further down the
upgrade road.
