How to create a measure to calculated Rolling 7 day average to use in matrix ?

[lavdeepk]

Hi All,

I have a day-wise collection matrix visual and in the next field of the matrix visual,  I want to show the Rolling 7-day average collection.

Refer to the below sample table ( in power bi this is matrix visual) where I have type desired output. I need output like this.

Day	Collection_INR(Cr)	Rolling 7 day average Coll (desired output)
01-Nov	0.3	-
02-Nov	0.4	-
03-Nov	0.4	-
04-Nov	0.2	-
05-Nov	0.4	-
06-Nov	0.1	-
07-Nov	0.1	0.3
08-Nov	2.5	0.6
09-Nov	1.6	0.8
10-Nov	2.3	1.0
11-Nov	3	1.4
12-Nov	2.3	1.7
13-Nov	0.9	1.8
14-Nov	0.6	1.9
15-Nov	4.8	2.2
16-Nov	2.4	2.3
17-Nov	3.8	2.5
18-Nov	2.8	2.5
19-Nov	1.1	2.3

Thanks

Hi @lavdeepk ,

With the index column created, try the following code.

Rolling 7 day average = 
IF (
    ( MAX ( 'Table'[Index] ) - 7 ) < 0,
    BLANK (),
    CALCULATE (
        SUM ( 'Table'[Collection_INR(Cr)] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Index] <= MAX ( 'Table'[Index] )
                && 'Table'[Index]
                    >= MAX ( 'Table'[Index] ) - 7
        )
    ) / 7
)

If the problem is still not resolved, please point it out. Looking forward to your reply.

Best Regards,
Henry

Try:

Rolling 7 day average =
AVERAGEX (
    FILTER (
        ALL ( 'Date Table'[Date] ),
        'Date Table'[Date]
            > MAX ( 'Date Table'[Date] ) - 7
            && 'Date Table'[Date] <= MAX ( 'Date Table'[Date] )
    ),
    SUM ( 'Table'[Collection INR] )
)
