title: Matplotlib savefig does not save axes
body: <p>I'm trying to save a figure that works fine in IPython inline but does not save the figure to disk with the axes and titles included.</p>
  <p>I am using TKAgg backend by default in matplotlibrc.</p>
  <p>Any ideas what might be going wrong here? I have clearly set the xlabel and the tick marks work correctly in IPython inline plot.</p>
  <pre><code>import matplotlib.pylab as plt  
  x = [1,2,3,3]
  y = map(lambda(x): x * 2, x)
  fig = plt.figure()
  ax = fig.add_axes([0,0,1,1])
  ax.set_title(&quot;bleh&quot;)
  ax.set_xlabel(&quot;xlabel&quot;)
  ax.plot(x, y, 'r--')
  fig.savefig(&quot;fig.png&quot;)
  </code></pre>
