Adding two legend values

[Anonymous]

Hi, I have a line graph with three lines that show the count of customers for each Yearmonth for multiple legends values A, B, and C. I want to add another line that shows the value of legend A+B. Is that possible to do?

Legend	Customers	YearMonth
A	1212144	201904
A	9999921	201904
A	2121212	201903
B	2121212	201904
B	2121212	201904
B	2221111	201903
C	4414141	201903
C	2121212	201903
C	7111212	201902
C	7777721	201904
C	8232323	201904
C	3333212	201902
