title: Matplotlib not listening to font choices
body: <p>I am unable to avoid an error in matplotlib regarding font choice. Whenever I try to plot on a remote machine in Linux I get the following error:</p>
  
  <pre><code>/home/josh/anaconda/envs/py27/lib/python2.7/site-packages/matplotlib/font_manager.py:1236:
  UserWarning: findfont: Font family ['Arial'] not found. 
  Falling back to Bitstream Vera Sans 
  (prop.get_family(), self.defaultFamily[fontext]))
  </code></pre>
  
  <p>I have edited my <code>.matplotlibrc</code> file (just in case, in two locations):</p>
  
  <ul>
  <li><code>.matplotlib/.matplotlibrc</code></li>
  <li><code>.config/matplotlib/.matplotlibrc</code></li>
  </ul>
  
  <p>Where I added the following lines:</p>
  
  <pre><code>backend: Agg
  font.family        : serif
  font.serif         : Times, Palatino, New Century Schoolbook, Bookman, Computer Modern Roman
  font.sans-serif    : Helvetica, Avant Garde, Computer Modern Sans serif
  font.cursive       : Zapf Chancery
  font.monospace     : Courier, Computer Modern Typewriter
  text.usetex        : true
  </code></pre>
  
  <p>Still, <code>matplotlib</code> keeps complaining about <code>Arial</code>. Why? (note this is when running a script with <code>python my_script.py</code>) with no IPython involved. </p>
