Cumulative Distinct count based on months

[Vamshi2020]

Hi Everyone ,

I have a Requirement to show Cumulative count based on "Month -Year" in Line chart . Based on selections in Dim Date slicer, my value should change . My Actual count formula is :
Count= 
var a=MINX(DimDate,DimDate[Date])
var b=MAXX(DimDate,DimDate[Date])
var c=calculate(Distinctcount(MemberTable[MemberId]),Filter(MemberTable , MemberTable[StartDate]<=b && MemberTable[EndDate]>=a))
return c

The above formula is giving the proper results, but in other line chart i want to see cumulative count for each months.

So i wrote like below:

Cumulative =Calculate(MemberTable[Count],DATESYTD(DimDate[Date],"31/12")

But this is not working , 

Please help me with the requirement .

TIA

Hi @Vamshi2020 ,

Try this:

Cumulative Count =
VAR a =
    MINX ( ALLSELECTED ( DimDate ), DimDate[Date] )
VAR b =
    MAXX ( DimDate, DimDate[Date] )
VAR c =
    CALCULATE (
        DISTINCTCOUNT ( MemberTable[MemberId] ),
        FILTER ( MemberTable, MemberTable[StartDate] <= b && MemberTable[EndDate] >= a )
    )
RETURN
    c

Best regards
