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?
I only had python 2.5 and I did not want to install python 2.6 on my mac. So I used different procedure mentioned in the following link to solve this problem:

What that one actually needs is the following steps:
1) Searching where is the directory "pygtk-2.0.pc" and locate it. For example mine was located in the following directory:
/opt/local/lib/pkgconfig
2) Adding the path information to envirement variable. For example:
PKG_CONFIG_PATH=/opt/local/lib/pkgconfig
export PKG_CONFIG_PATH
3) Download the configuration information file "matplotlibrc" from matplotlib website http://matplotlib.sourceforge.net/_static/matplotlibrc
4) Change backend to MacOSX in the file and save it
5) Copy the file to directory .matplotlib You can locate the directory in python by the following command:
import matplotlib
matplotlib.get_configdir()
