Hi qwerty4546,

Are you sure you mean "Say I have 50 stores"?
I ask this because you later state "for the two stores"
Do you mean "Say I have 50 products"?

Are you wanting a bar chart with two bars, one bar for each of the two
stores and each store's bar size representing its total revenue, and
then each of the two bars subdivided into fifty parts, 1 part for each
product's contribution to the total revenue?
