title: save pandas plot with subplots to one file
body: <p>I am creating subplots in pandas/jupyter notebook from the following dataframe </p>
  
  <pre><code>METHOD1       A           B             C              D             E
  METHOD2                                                                
  high       1410          14           426          13781             1
  low       74142         303        757024          95105            37
  medium    99174         670        277013         640000           127
  mono      46599         207        405108          16793           160
  
  axs = ct.plot(kind='barh', subplots=True, legend=False, figsize=(24,16))
  for ax in axs:
      ax.set_xscale('log')
  </code></pre>
  
  <p>In Jupyter I get one image with 4 subplots. I want to save that plot to one png,
  but </p>
  
  <pre><code>fig=axs.get_figure()
  fig.savefig('plot.png')
  </code></pre>
  
  <p>gives an error message </p>
  
  <blockquote>
    <p>AttributeError: 'numpy.ndarray' object has no attribute 'get_figure'   </p>
  </blockquote>
  
  <p>because axs is an array of the subplots
  I can save the individual subplots.</p>
  
  <p>How can I save all the subplots to one image? </p>
