title: matplotlib border width
body: <p>I use matplotlib 0.99.</p>
  
  <p>I am not able to change width of border of <code>subplot</code>, how can I do it? </p>
  
  <p>Code is as follows:</p>
  
  <pre><code>fig = plt.figure(figsize = (4.1, 2.2))
  ax = fig.add_subplot(111)
  
  ax.patch.set_ linewidth(0.1) 
  ax.get_frame().set_linewidth(0.1) 
  </code></pre>
  
  <p>The last two lines do not work, but the following works fine:</p>
  
  <pre><code>legend.get_frame().set_ linewidth(0.1)
  </code></pre>
