Help to amend my Rolling Average calculation.

[Shales]

Hello,

I am looking for some help to tweak a Measure I have that isn't quite working. I am a bit of a novice so I apologies in advance for any incorrect terminolgy or just poor explainations.

My data is Football/Soccer and what I am trying to acheive is having a rolling Average of Goals scored per Player by IndexNumber. All my data is in a table called MatchData1.

I currently have this measure;

4GameGPG measure =
VAR __Index = MAX(MatchData1[Rank])
VAR __MinIndex = __Index - 3
VAR __Table = FILTER(ALLSelected(MatchData1), MatchData1[Rank]<= __Index && MatchData1[Rank] >= __MinIndex)
RETURN
AVERAGEX(__Table,[Goals])​

The measure currently works if I only have 1 person selected in my visual(table). When I select more than 1 person then gives each person the same average for each Rank. I believe I need the Var__Table section of the code to be amended but this is where I am stuck.

Just for reference, here is my Rank DAX;

Rank =
VAR d = MatchData1[Date]
VAR c = MatchData1[Players]
RETURN
CALCULATE (
RANK.EQ ( d, MatchData1[Date], Asc ),
FILTER ( ALL ( MatchData1 ), MatchData1[Players] = c )
)

Any help would be really appreciated 🙂.

Thanks,
Gavin
