Moving average / moving variance
You are mixing 2 different measures. One is the 12-month average and the other is the sum of the 12-month averages. If you want to have these 2 morphed into one... then you'll need to write a SWITCH which will select the measure based on what time period is in scope.
Actually... on reflection, you can do something simpler: you can write a measure that will sum up the averages over the currently visible pieces of time. If you never go below the month level, then it's even easier. Hide the individual dates so that they can't be selected, leave only pieces of time from the month up and write:
sumx(
VALUES ( Calendar[YearMonth] ),[12M Average]
)
This will give you what you want.

That looks good, thank you!
Although it didn't solve my intiial question on how to calculate the moving variance, accordingly, without having to write the variance formula explicitly. I hoped to find a way to calculate the desired moving average by using the function Averagex and adapt the filter settings to a different measure with the VARX.P function.
