title: Boxplot of Multiple Columns of a Pandas Dataframe on the Same Figure (seaborn)
body: <p>I feel I am probably not thinking of something obvious. I want to put in the same figure, the box plot of every column of a dataframe, where on the x-axis I have the columns' names. In the <code>seaborn.boxplot()</code> this would be equal to <code>groupby</code> by every column. </p>
  
  <p>In pandas I would do </p>
  
  <pre><code>df = pd.DataFrame(data = np.random.random(size=(4,4)), columns = ['A','B','C','D'])
  df.boxplot()
  </code></pre>
  
  <p>which yields</p>

  <p>Now I would like to get the same thing in seaborn. But when I try <code>sns.boxplot(df)</code>, I get only one grouped boxplot. How do I reproduce the same figure in seaborn? </p>
