summing a measure in range date

[Genius]

I have write this measure and visualize this in histogram

CSSHSommaBudgetMensile = var startDate = 'Date'[Da]

var endDate = DATE(YEAR('Date'[A]),MONTH('Date'[A]), DAY(EOMONTH('Date'[A],0)))

return CALCULATE(

             SUM(CSS_Details_H[BudgetTot])/1000000,CSS_Details_H[Unit] <>"UP_TRRVLDLIGA_S",

             FILTER(

            ALL ( 'CSS_Details_H'[Date]),

            CSS_Details_H[Date] >= startDate

                && CSS_Details_H[Date] <= endDate

        )        )

This is a granularity monthly hinstogram. I would like to commute the measure into of each colum in a sum of the corresponding column withe previuos ones between start date and end date (variabel calculated in the measure)

Example

Colum a= a

Colum b= a+b

Colum c=a+b+c

and so on
