Matplotlib doesn't display graph in virtualenv

Answer 1

Your code works inside my virtualenv on OSX 10.7 with Python 2.7:

What version of Python are you using inside your virtualenv? My guess is that either you have not installed a matplotlib dependency or your installation of an installed dependency was not properly performed. On Python 2.7 here is what I did to install matplotlib. Can you try these steps in a new virtualenv and see if it works for you?

pip install numpy
pip install scipy
easy_install matplotlib
