12 month rolling average

Client wants 12 month rolling average.  If I were to choose September 2021 for my Date of Service, then how can I get that Date of Service filter to automatically consider the 12 months in total?

 

1 month, September 2021.

 

12 Months total ...

 

Thank you for your time in hoping you can figure this out!!!

    HI jonnyA,

    You can create a table to extract date value and use it as the category of your visual.
    Then you can write a measure formula to extract the current date value as a condition to looping table records and get cumulative results.

    Measure =
VAR currDate =
    MAX ( 'Date'[Date] )
RETURN
    CALCULATE (
        AVERAGE ( Fact[Price] ),
        FILTER (
            ALLSELECTED ( Fact),
            Fact[Date]
                >= DATE ( YEAR ( currDate ) - 1, MONTH ( currDate ), DAY ( currDate ) )
                && Fact[Date] <= currDate
        )
    )

    Regards,
