title: Bold text with AnchoredText (Python and Matplotlib)
body: <p>Is it possible to render the text bold with an AnchoredText?</p>
  
  <pre><code>plt.figure() 
  ax = plt.subplot(3,1,1) 
  anchored_text = AnchoredText("a", loc=2,borderpad=0.,frameon=False)
  ax.add_artist(anchored_text)
  </code></pre>
  
  <p>I don't find what parameter I can add to make the text bold.</p>
