Merge boxplots from two dataframes Python

Question

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:

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'))

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.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?)

Thanks in advance!
