Hi Everyone,
I have calls and I need to represent it. I have a sum of abandoned ( green) , a sum of attended ( purple) and a sum of total(yellow line) calls.
My problem is that the line is not the real sum for this day, I think that it is sum since month back but to calculate. What I could do?

I intented do a 'group by' but the problem continues.

It is cause of the type of graph? I could change options?

note: the field MES it is the date completly but I only represent the name of month.
thanks!
