title: Boxplots in a matrix with matplotlib
body: <p>Need to obtain 24 boxplots in two columns (12 per row) and print them into a postscript file.</p>
  
  <p><strong>This code throws an error</strong></p>
  
  <pre><code>def do(self, ...):
      axarray = plt.subplots(12, 3, figsize=(11.69,8.27))
      for i in range(2):
          for month in range(12):
              monthBoxplot = [    [ 2, 2, 2 ], 
                                  [ 2, 2, 2 ] ]
              axarray[i, m].boxplot(monthBoxplot)
      ax.imshow(axarray, aspect='normal')
      plt.savefig("/asdasd"+str(year)+".ps")
  </code></pre>
  
  <p><strong>The error</strong></p>
  
  <blockquote>
  <pre><code>axarray[i,m].boxplot(boxplotMensual)
  </code></pre>
    
    <p>TypeError: tuple indices must be integers, not tuple</p>
  </blockquote>
  
  <p><strong>It means that <code>[i,m]</code> is a tuple...right? What should i do?</strong>
  Thanks</p>
