Difference of daily change of running total compared to one customer

[IvanS]

Hi all, 

I am trying to create the table based on comparison of running total vs. one customer - example below:

Date	Customer	Sales	Difference
1/1/2022	A	1000	100
1/1/2022	B	800	-100
1/1/2022	C (to compare with)	900	0
2/1/2022	A	1300	200
2/1/2022	B	1100	0
2/1/2022	C (to compare with)	1100	0

I would need to visualise this in graph like below (where green color represents the customer C against which the difference is being calculated). I did not find any visual in PBI store that could provide such insight so therefore I am looking for DAX calculation.

Any help is much appreciated!

Ivan

You would need to split the talble into two: Customers that will be compared against Customer C, and, obvously, Customer C. Join them back together on Date ONLY. Note that you may need to do all this in Power Query. Your larger table will now have, on each row, the value of the Customer in question, and the value for Customer C.

Plotting should be fairly easy after that.

Hope that helps.

Thank you so much! Very nice workaround instead of DAX formula. 🙂
