maxima plot problem on OS X lion



Jan, Thank you. After some further investigations, I switched to 
use x11:

in maxima-init:

   set_plot_option([gnuplot_term, x11])$

and maxima plot window shows up.

I also put in my .bashrc:

  export GNUTERM='x11'

and the broken Octave plot is back too.

Lion does not come with X11. I downloaded XQuartz and linked
X11.app to XQuartz.app.
