Re: Plot command crashes Octave

Ben,

I knew I was using qt graphics_toolkit. 

gnuplot toolkit also worked.  qt seemed faster and cleaner looking.

Thanks for the feedback. One clarifcation, the commend below selects the Qt OpenGL graphics toolkit (i.e. does not use gnuplot).

        graphics_toolkit (“qt”)

Some of the errors you reported were produced by gnuplot. Does the result below also work?

        graphics_toolkit gnuplot
        setenv GNUTERM qt
        close all
        plot (rand (3))

In any event, since the app-bundle you obtained from the wiki did not include “—universal” when installing fontconfig, it is likely this is the root of the problem.
