Dear Statafriends

I constracted some marginal plots, and now, I would like to plot the difference between the graph numvar = 2019q3 and the graph numvar = 2015q3 to get a nicer figure. Could somebody help me, please? I really don't know how. This was the code to get the marginsplots.

Code:
reg employment_rate i.salhora_categories i.numvar if numvar == 222 | numvar == 238 | numvar == 240
margins salhora_categories##numvar
marginsplot
