title: Pycharm does not show plot
body: <p>Pycharm does not show plot from the following code:</p>
  
  <pre><code>import pandas as pd
  import numpy as np
  import matplotlib as plt
  
  ts = pd.Series(np.random.randn(1000), index=pd.date_range('1/1/2000', periods=1000))
  
  ts = ts.cumsum()    
  ts.plot()
  </code></pre>
  
  <p>What happens is that a window appears for less than a second, and then disappears again.</p>
  
  <p>Using the Pyzo IEP IDE (using same interpreter) on the same code the plot shows as expected.</p>
  
  <p>...So the problem must be with some setting on Pycharm.
  I've tried using both python.exe and pythonw.exe as interpreter both with same results.</p>
  
  <p>This is my sys_info:</p>
