To get Previous weeks data from the selected week and compare the changes

[Praj]

Hi Everyone,

I have a dataset which provides insights about the viewership. I trying to find the viewrship changes in percentage when compared to previous week to the selected week. My date column is in DD/MM/YYY format and I am using the timeline filter.

So I am trying to find a way so that whenever my user selects any week, there should be a card which gives the % change in viewership

Any suggestions/approach for this problem is highly appreciated.

Cheers,

Praj

Add a week commencing column to your date table and then you could use something like

Week on week change =
VAR CurrentWeekStart =
    SELECTEDVALUE ( 'Date'[W/C] )
VAR CurrentValue = [viewers]
VAR PrevValue =
    CALCULATE (
        [viewers],
        REMOVEFILTERS ( 'Date' ),
        'Date'[W/C] = CurrentWeekStart - 7
    )
VAR Result =
    DIVIDE ( CurrentValue - PrevValue, PrevValue )
RETURN
    Result
