title: matplotlib changing barplot xtick labels and sorting the order of bars
body: <p>I have a dataset that i'm trying to plot,
  this is how I plot it:</p>
  
  <pre><code>   for i in range(0,5):
      plt.subplot2grid((1,5),(0,i))
      df.Survived[df.SibSp == i].value_counts().plot(kind='bar')
      title(str(i))
  </code></pre>
  
  <p>the values in X (survived) are 0 or 1 and i'm plotting the value count of them.
  I'm trying to change the xSticks to "survived"\"not survived", how can I do it?</p>
  
  <p>and I'm also trying to sort the xSticks at all graphs at the same way (as you can see in the pic the default is to sort according to ycount, which is causing the x's to be 0-1 at the first graph and 1-0 at the second graph)
