title: How to recover matplotlib defaults after setting stylesheet
body: <p>In an ipython notebook, I used a matplotlib stylesheet to change the look of my plots using </p>
  
  <pre><code>from matplotlib.pyplot import *
  %matplotlib inline
  style.use('ggplot')
  </code></pre>
  
  <p>My version of matplotlib is 1.4.0. How do I go back to the default matplotlib styling? I tried all the available styles in</p>
  
  <pre><code>print style.available 
  </code></pre>
  
  <p>but there doesn't seem to be a "default" option. I also tried </p>
  
  <pre><code>matplotlib.rcdefaults() 
  </code></pre>
  
  <p>For some reason, this gives me a gray background. It also changes the text from gray (ggplot style) to black, which may be the default, but also could be another random style. </p>
