title: Title for side by side pie charts in matplotlib
body: <p>The following code produces two pie charts side by side. Is there any way to add a title for each of the two pie charts - preferably above the chart itself?</p>
  
  <pre><code>labels = 'Frogs', 'Hogs', 'Dogs', 'Logs'
  fracs = [15, 30, 45, 10]
  
  fig = plt.figure()
  
  ax1 = fig.add_axes([0, 0, .5, .5], aspect=1)
  ax1.pie(fracs, labels=labels, radius = 1.2)
  ax2 = fig.add_axes([.5, .0, .5, .5], aspect=1)
  ax2.pie(fracs, labels=labels, radius = 1.2)
  plt.show()
  </code></pre>
