help generating Plots on Mac Pro OSX 10.4.11

[Stuart Borrett]

Ben, David, et al.,
Thank you for your help.  I have installed Aquaterm on my Mac Pro and this
now allows Octave to plot.

I remain confused however as to why Octave can plot on my MacBook Pro.  It
plots fine and as far as I can tell does not have Aquaterm installed.

One last thought.  Is there anyway for Octave to take advantage of
Hyperthreading and/or multiple processors?  I just ran a comparison with
Matlab, and Octave was MUCH slower and I believe the reason is that it could
only use one thread/core.

Thanks again for your help.

Respectfully,

Stuart
