Does someone know how can I create a grouped chart with 2 series?
I would like to sum value from 2 products filtered and compare it on the same graph. But it's a index view, so I have to calculate the index (done at the backend of the data) and sum all value from each range I've got, like this image
So I choose product 1 and product 2 (both on the same row with index column already calculated)
the thing is, if I could use multiple series, I could create the graph I need, but It would give me the opportunity to add one more.
Is that another chart I can use or something I can change to get this?
