You have 4 options to allow for plotting. The simple options is to use the fltk 
backend. For that just start your octave session with the command below.

        graphics_toolkit fltk

The remaining three options require that gnuplot be installed. You can do this 
using the MacPorts package manager, the Fink package manager, or by building 
and installing gnuplot yourself.

If you're unfamiliar with these options, and want to install gnuplot, I 
recommend using MacPorts. Both the MacPorts and Fink package managers handle 
downloading sources, building and installing applications like gnuplot and 
octave. Unfortunately the latest version of Octave, supported by Fink, is 
3.0.5. MacPorts has a package available for 3.4.2

If these gnuplot options don't look attractive to you it is possible that other 
Mac users on the helo-list may have additional suggestions.
