title: How to plot multiple pandas dataframe as separate categories in a violinplot?
body: <p>I am reading data from four separate files of different categories and would like to visualize the distribution of a filed for those using a violin plot. In my attempt, it seems like they are getting overwritten</p>
  
  <pre><code>import seaborn as sb
  
  # category1, category2, category3, category4 are pandas dataFrame obj
  
  sb.violinplot(category1['delay'])
  sb.violinplot(category2['delay'])
  sb.violinplot(category3['delay'])
  sb.violinplot(category4['delay'])
  </code></pre>
