title: Python plots won't open
body: <p>I found this example for a simple plot on <a href="http://www.loria.fr/~rougier/teaching/matplotlib/#simple-plot" rel="nofollow">http://www.loria.fr/~rougier/teaching/matplotlib/#simple-plot</a>:</p>
  
  <pre><code>from pylab import *
  
  X = np.linspace(-np.pi, np.pi, 256,endpoint=True)
  C,S = np.cos(X), np.sin(X)
  
  plot(X,C)
  plot(X,S)
  
  show()
  </code></pre>
  
  <p>But then absolutely nothing happens. No errors, no warnings, just nothing. Same thing whether it be in the terminal or in Eclipse. I'm using Python 2. Am I missing something?</p>
  
  <p>Thanks!</p>
