Rolling average last 3 rows

Hi, I'm new here and I need some help.

I would like to calculate a "W-kee" rolling average over the last 3 rows in the table example as below:

So the result should be ((1+4+1)/3=2), but I don't know what DAX formula I need to use.

I think I should use something based on nonblank rows for the W-kee column but I really have no glue.

Please help.

Hi, 

According to your description, I can roughly understand your requirement, you can try this measure to get the expected result:

Rolling average =

var _lastrow=CALCULATE(MIN('Table'[SPR]),FILTER(ALL('Table'),[W-kee]=BLANK()&&[W-def]=BLANK()&&[W-mid]=BLANK()&&[W-att]=BLANK()))

return

CALCULATE(AVERAGE('Table'[W-kee]),FILTER(ALL('Table'),[SPR]<=_lastrow-1&&[SPR]>=_lastrow-3))

 

And you can get what you want, like this:

Hi @jdevalk ,

 

var Rolling Average= CALCULATE(Table[W-knee], FILTER(ALLSELECTED(Table[SPR]), ISONORAFTER( Table[SPR], MAX(Table[SPR]), asc)))
Return  (Rolling Average/ 3)

Mark this as a solution, if I answered your question. Kudos are always appreciated.

Thanks

Hi @jdevalk 

 

Try this measure:

Measure=
Var _MaxL = calculate(max(table[SPR]),filter(table,table[W-kee]<>""))
Var _MinL = _MaxL-2
return
Calculate(avarage(table[W-kee]),filter(table,table[SPR]>=_MinL &&table[SPR]<=_MaxL ))
