Introduction

[http://matplotlib.sf.net MatPlotLib] is a module to produce nice-looking plots in Python using a wide variety of back-end packages, at least one of which is likely to be available for your system. This ability to do things in a generic fashion makes this a simple system to use, but it gets complicated if you wish to distribute an executable instead of scripts. This page describes what I had to do to make matplotlib work with py2exe.

Special content for setup.py to use matplotlib

= Changes required to matplotlib =
I had to patch matplotlib's __init__.py file in the get_data_path() routine.  Specifically, right before raising the error at the end, I added the following code
{{{
#!python
      # CODE ADDED TO SUPPORT PY2EXE
      if sys.frozen:
         path = os.path.join(os.path.split(sys.path[0])[0], 'matplotlib')
