title: How do I set the figure title and axes labels font size in Matplotlib?
body: <p>I am creating a figure in Matplotlib like this:</p>
  
  <pre><code>from matplotlib import pyplot as plt
  
  fig = plt.figure()
  plt.plot(data)
  fig.suptitle('test title')
  plt.xlabel('xlabel')
  plt.ylabel('ylabel')
  fig.savefig('test.jpg')
  </code></pre>
  
  <p>I want to specify font sizes for the figure title and the axis labels. I need all three to be different font sizes, so setting a global font size (<code>mpl.rcParams['font.size']=x</code>) is not what I want. How do I set font sizes for the figure title and the axis labels individually?</p>
