title: How to plot pandas.crosstab() columns
body: <p>I am trying to plot in the same figure the first <em>n</em> values which are the results of <code>pd.crosstab()</code>, I have tried:</p>
  
  <pre><code>tab = pd.crosstab(df['genre_ids'], df['target'],margins=True).sort_values('All',ascending=False)
  tab = tab.drop('All',axis=1)
  tab = tab.drop('All',axis=0)
  tab[:top_n].plot(kind='bar', stacked=True)
  plt.show()
  </code></pre>
  
  <p>but I get a <em>barplot</em> that doesn't rappresent the actual values present in the <em>tab</em>'s columns.</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>This is the <em>crosstab</em>:

  I would like plot the values in columns <em>0</em> and <em>1</em>, but I get this plot that it's different from the values in the columns:

  Is it possible get something like this:<a href="https://i.stack.imgur.com/z2Pxe.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/z2Pxe.png" alt="enter image description here"></a>
  but with the <em>0</em> and <em>1</em> values plot in the same bar for each x-value?</p>
