    Hi Anonymous ,

     

    I suggest you to create a DimDate table with continuous date if you want to use DATESBETWEEN() which is a time intelligence function.

    Try CALENDAR() or CALENDARAUTO().

    DimDate = ADDCOLUMNS( CALENDARAUTO(),"Year",YEAR([Date]),"Month",MONTH([Date]))

    My Sample:

    Measure:

    Measure = 
AVERAGEX(
DATESBETWEEN(DimDate[Date],MIN(DimDate[Date]),MAX(DimDate[Date])),
CALCULATE(sum('Data (10)'[Count]))
)

    Then add Year/Month columns into Axis. Result is as below.

     

    Best Regards,
    Rico Zhou

Anonymous , Make sure the data type is date, why both are max

always use date table

try like

 


CALCULATE
( AVERAGEX(values('Data (10)'[RequestDateRaised - Copy]),
CALCULATE(sum('Data (10)'[Count]))
),DATESBETWEEN('Date'[Date],min('Date'[Date]),max('Date'[Date])))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.
