Average for each small multiple

Hi MuthalibAbdul 

It seems that you're using the average from "Add further analyses to your visual" which unforunately returns the average for all. If you want the average for each small multiple by month, create a measure

Monthly Average = 
AVERAGEX ( ALLSELECTED ( 'Date'[Month] ), [Row Count] )

Monthly Average Label = 
VAR _maxMonth =
    MAXX ( ALLSELECTED ( 'Date'[Month] ), [Month] )
RETURN
    IF ( SELECTEDVALUE ( 'Date'[Month] ) = _maxMonth, [Monthly Average] )

You'll need to use a custom data label to be able to show the label only for  a specific data point.
