title: Violin Plot with python
body: <p>I want to create 10 violin plots but within one diagram. I looked at many examples like this one: <a href="http://matplotlib.org/examples/statistics/boxplot_vs_violin_demo.html" rel="nofollow noreferrer">Violin plot matplotlib</a>, what shows what I would like to have at the end.</p>
  
  <p>But I did not know how to adapt it to a real data set. They all just generate some random data which is normal distributed.
  I have data in form D[10,730] and if I try to adapt it from the link above with :
  example:</p>
  
  <pre><code>axes[0].violinplot(all_data,showmeans=False,showmedians=True)
  </code></pre>
  
  <p>my code:</p>
  
  <pre><code>axes[0].violinplot(D,showmeans=False,showmedians=True)
  </code></pre>
  
  <p>it do not work. 
  It should print 10 violin plot in parallel (first dimension of <code>D</code>).</p>
  
  <p>So how do my data need to look like to get the same type of violin plot? </p>
