I am user of wxMaxima since a lot of years, in a Linux (Ubuntu) system.
In that system, I have no problems with plotting or drawing functions.
Now, I use an iMac, too, with system 10.8.2, where I have wxMaxima
12.08.0 and Maxima 5.28.0 installed.
When I try to use the plot or draw command, no drawings appear, wxMaxima
simply 'hangs', no errors are reported on the screen.
Plotting functions only with Gnuplot (version 4.6.1 is installed) works
well in both, x11 and AquaTerm.
Have you any idea how to 'convince' the system to plot or draw directly
from wxMaxima?
With my best regards,
H. Ballmann
