    Hi Uzi2019 ,

     

    Please try:

    First create an index column:

    Then apply the measure:

    Measure =
VAR _a =
    STDEVX.S (
        FILTER (
            ALL ( 'Table' ),
            [Index] <= MAX ( 'Table'[Index] )
                && [Index]
                    >= MAX ( 'Table'[Index] ) - 1
        ),
        [revenue]
    )
VAR _b =
    MINX ( ALLEXCEPT ( 'Table', 'Table'[channel] ), [date] )
RETURN
    IF ( MAX ( 'Table'[date] ) = _b, BLANK (), _a )

    Then show items with no data:

     

    Final output:

    Best Regards,

    Jianbo Li

Uzi2019 Try something like this:

 

Measure = 
  VAR __Date = MAX('Table'[Date])
  VAR __NextDate = MINX(FILTER(ALL('Table),[Date] > __Date),[Date])
  VAR __CurrentValue = MAX('Table'[revenue])
  VAR __NextValue = MAXX(FILTER(ALL('Table'),[Date] = __NextDate),[revenue])
  VAR __Result = STDDEVX.S( { __CurrentValue, __NextValue }, [Value])
RETURN
  __Result
