title: How to plot on box plot 2 data from different data frama - Python
body: <p>I'm facing a problem to plot 2 box plots into a same graph to make easier to compare them.
  The problems is that each box plot comes from a different dataframe with different lenght, however, both have same columns.</p>
  
  <p>My two data frame are:
  'headlamp_water' and 'headlamp_crack'; the column I want to use is called 'Use Period'.
