title: Merge boxplots from two dataframes Python
body: <p>So I've plotted two separate boxplot graphs on python - each has multiple columns - they have the same x-axis bins and the is the same variable on the y-axis but show different machinery.  I have managed to plot them on two seperate plots using:</p>
  <pre><code>df1.boxplot(by ='Temperature', column =['Pressure 1'], grid = True, fontsize=50, figsize=(90,50), boxprops=dict(color='black'))
  
  df2.boxplot(by ='Temperature', column =['Pressure 2'], grid = True, fontsize=50, figsize=(90,50), boxprops=dict(color='black'))
  </code></pre>
  <p>So I end up with the two seperate box plots I want, but how can I get them onto one graph so they're more easily comparible?</p>
  <p>(P.s. as a side note, I'm plotting like 8 boxes on each plot so they can become hard to read is there any way to make the boxes and whiskers bolder?)</p>
  <p>Thanks in advance!</p>
