Rolling average Last Month and Current Month

Hi,

I have two tables:

BLUE: Table used for Date slider/slicer
RED: Table used for all other dimensions/measures






I am plotting 'sum of flag' in a timeline.

I wish to plot rolling average of 'this month and last month' in the timeline.

That means for January: 5 is okay.
For February: it should be (5+4) / 2 = 4.5
For March: (4+3)/2 = 3.5

Can someone please help me with that.


Thanks !

    Hi Anonymous ,

    Sorry about that, try this:

    myMeasure = 
VAR _monthNumberCurrent =    MAX ( mytable[monthNumber] ) //get the month number from this row

var _thisMonthFlag = MAX(myTable[Flag])
VAR _prevMonthNumber =
    CALCULATE (
        MAX ( mytable[monthNumber] ),
        FILTER ( ALL ( myTable ), myTable[monthNumber] < _monthNumberCurrent )
    ) //filter the table to all month numbers less than this month number, and get the max value which is the month before

var _lastMonthFlag = CALCULATE(MAX(myTable[Flag]),FILTER(ALL(myTable),myTable[MonthNumber]=_prevMonthNumber))

RETURN
    DIVIDE ( _thisMonthFlag + _lastMonthFlag, IF(_lastMonthFlag = 0,1,2 ))

    Hi Anonymous  JohnShepherdAPD ,
    If I understand your issue correctly, please try this measure:

    myMeasure =
VAR _monthNumberCurrent =
    MAX ( mytable[monthNumber] ) //get the month number from this row
VAR _prevMonthNumber =
    CALCULATE (
        MAX ( mytable[monthNumber] ),
        FILTER ( ALL ( myTable ), myTable[monthNumber] < _monthNumberCurrent )
    ) //filter the table to all month numbers less than this month number, and get the max value which is the month before
RETURN
    DIVIDE ( _monthNumberCurrent + _prevMonthNumber, 2 )


    Let me know if you have any questions.

      Hi Nathaniel_C ,

      Thanks for this.

      I am actually looking for average of [Flag] on those months ...

      In the timeline on the right bottom corner ...
      For February: it should be (5+4) / 2 = 4.5
      For March: (4+3)/2 = 3.5

      The final measure will be 2 months rolling average ...

      Many thanks
