title: Plotting several boxplots from different dataframes in one graph
body: <p>I'm trying to plot several boxplots from different dataframes in one graph. Each dataframe has a different length.</p>
  <p>What I'm doing is the folowing:</p>
  <pre><code>sns.boxplot(x=df1['Numbers'])
  sns.boxplot(x=df2['Numbers'])
  sns.boxplot(x=df3['Numbers'])
  sns.boxplot(x=df4['Numbers'])
  </code></pre>
  <p>However, the output of doing that is that all boxplots are ploted one over the other and it's not possible to distinguish anything.</p>
  <p>Can you help me with this?
  Regards</p>
