Matplotlib plots not showing up in Mac OSX?

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: … 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?



Have you tried contacting Matplotlib support? This is the support forum for Scrivener, a very different product.
