I need your help for this case I can't resolve myself.
I have a single table with
- Id_Store= store
- Date= date of a measurement, there is multi date by store
- Value = value of measurement
I want to make a graphic (table or histogram) with store as dimension & value as expression
but with a choice of date, example : for the last date (what is my last income on my last campaign)
Of course last dates are different for each store.
If it's possible for the last, how can i do with the first date, or any ranking date. I don't have the rank on the input file but maybe I should create it.
