Hello everyone,
I want to work whit matplotlib and I installed it using pip command.
Apparently the installation was successful and when I open ipython and
import matplotlib everything works well. Nevertheless when I try to import
pyplot using: import matplotlib.pyplot I obtain this:
---

I have installed the libpng library as was suggested in other post but
nothing worked. I am working with a Mac OS X 10.7.5 and I have installed the
XQuartz 2.7.4. I really do not have a clue about what is happening with
that, I would appreciate so much if you can help me figure this problem out.
All the best!
Milo.
