Accumulation in QlikSense

[#1]

Hi community

I´m new to QlikSense. I have a barchart which is counting various tasks per month. But now i wanna accumulate this taks over every month. In QlikView there is a checkbox to do this. But in QlikSense I´m still missing this checkbox. Is there a nice trick?

My expression looks like this:

=Count(if(Methode = 'A3',Month))

There is screesnhot of my actual barchart.

Thanks a lot!
