python - Matplotlib plots not showing up in Mac OSX?

Question

I am running Mac OSX 10.5.8. I installed matplotlib using macports. I get some examples from the matplotlib gallery like this one, without modification:

http://matplotlib.sourceforge.net/examples/api/unicode_minus.html

I run it, get no error, but the picture does not show up. In Linux Ubuntu I get it.

Do you know what could be wrong here?
