4 week rolling average

Hi  jnrezk ,

I created some data:

Here are the steps you can follow：

1. Create calculated column.

week = WEEKNUM('Table'[date],2)

weekday = WEEKDAY('Table'[date],2)

week_column =
var _lastweek=CALCULATE(MAX('Table'[week]),FILTER(ALL('Table'),YEAR('Table'[date])=YEAR(EARLIER('Table'[date]))))
return
IF([week]=_lastweek&&WEEKDAY(DATE(YEAR([date]),12,31),2)<>7,1,[week])

2. Create measure.

avg = CALCULATE(AVERAGE('Table'[value]),FILTER(ALL('Table'),'Table'[week_column]=MAX('Table'[week_column])&&YEAR('Table'[date])=YEAR(MAX('Table'[date]))))

min =
var _todayweek=WEEKNUM(TODAY(),1)
return
CALCULATE(MIN('Table'[date]),FILTER(ALL('Table'),'Table'[week_column]=MAX('Table'[week_column])&&'Table'[week_column]>=_todayweek-4&&'Table'[week_column]<=_todayweek))

Flag =
IF(
    MAX('Table'[date])=[min],1,0)

3. Place [Flag]in Filters, set is=1, apply filter.

4. Result:
