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 Anonymous
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 ))If this post helps, please consider accepting it as the solution to help the other members find it more quickly.
Appreciate your Kudos!!
Hi Anonymous
What is the format of [SPR] column?
Appreciate your Kudos!!
Hi Anonymous ,
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
