Help with plot on Macbook

[Ben Abbott]

You've installed a binary package that exists in your Applications  
folder. It is not easily run from a terminal.

My understanding is that for OSX 10.4 you'll need to start x11 prior  
to running octave in order for gnuplot to display the figures.

so ...

(1) Start x11 (it is in /Applications/Utilities)
(2) Start Octave (it is in /Applications)
(3) type "plot (1:10)"

Do you get a figure?

If not you *may* need to set the environment variable "display".  
Although I'd expect this has already be taken care of.

If you desire to run octave directly from the command line of the  
Terminal, or from an xterm (they are different), I'd suggest you  
install octave via MacPorts or Fink.
