title: Space between Y-axis and First X tick
body: <p>Matplotlib newbie here.  </p>
  
  <p>I have the following code:</p>
  
  <pre><code>from pylab import figure, show
  import numpy
  
  fig = figure()
  ax = fig.add_subplot(111)
  
  plot_data=[1.7,1.7,1.7,1.54,1.52]
  
  xdata = range(len(plot_data))
  
  labels = ["2009-June","2009-Dec","2010-June","2010-Dec","2011-June"]
  
  ax.plot(xdata,plot_data,"b-")
  
  ax.set_xticks(range(len(labels)))
  ax.set_xticklabels(labels)
  
  ax.set_yticks([1.4,1.6,1.8])
  
  fig.canvas.draw()
  
  show()
  </code></pre>
  
  <p>When you run that code, the resulting chart has a run-in with the first tick label (2009-June) and the origin.  How can I get the graph to move over to make that more readable? I tried to put dummy data in, but then Matplotlib (correctly) treats that as data. </p>
