@datagorillagirl , Assume you have date, if not create date with help from Month Year
Date = Datevalue("01-"&[Fiscal Month])
Join with date table, you that in slicer and axis
Try a measure like, if Ending HC is a column at the month level
Rolling 12 =
Rolling 12 =
new measure =
var _max = maxx(allselected('Date'),'Date'[Date])
var _min = minx(allselected('Date'),'Date'[Date])
var _diff = datediff(_min, _max, Month) +2
return
CALCULATE(Average(Table[End HC]),DATESINPERIOD('Date'[Date],Eomonth(MAX('Date'[Date]),1),-1*_diff ,MONTH))
or
Rolling 12 =
new measure =
var _max = maxx(allselected('Date'),'Date'[Date])
var _min = minx(allselected('Date'),'Date'[Date])
var _diff = datediff(_min, _max, Month) +2
return
CALCULATE(AverageX(Values('Date'[Date]), calculate(Lastnonblankvalues('Date'[Date], Sum(Table[End HC])))),DATESINPERIOD('Date'[Date],Eomonth(MAX('Date'[Date]),1),-1*_diff ,MONTH))
