I found the issue. It turns out that the x-axis on my tables was by week and the calculation in my measure was by day. I didn't realize this was an issue but glad it is solved.

 

However, this presents a new problem. I need this average but I also need to be able to display it in weekly form. It appears in my measue Day, Month, Quarter, and Year are the only ways I can calculate this. Is there any way I can do it by week instead?

Hi zgoodman,

In this scenario, you can firstly create a custom hierarchy with your Year, Quarter, Month, WeekNum, Date column, then you should be able to use this new created hierarchy to get your expected result. :smileyhappy:

    This looks great! Is there a way for me to label the week as the date at the beginnign of the week instead of the week number?

      Hi zgoodman,



      Yes, there is. You should be able to use the formula below to create a new calculate column in your Date table.

      FirstDayOfWeek = CALCULATE(FIRSTDATE('Date'[Date]),ALLEXCEPT('Date','Date'[WeekNo]))

       

      Then you can use the 'FirstDayOfWeek' column to create the custom hierarchy. :smileyhappy:

        It appears that becasue I am calculating the average using days instead of weeks I am still having the original problem of the graph looking funky when I display it in week form. Is there a way to do the actual calculation as 3 weeks instead of 21 days. Again, here is the formula:

         

        ^cpc_3_week = CALCULATE (
    AVERAGEX ( 'Query1', Query1[^cpc] ),
    DATESINPERIOD (
        Query1[isodate],
        LASTDATE ( Query1[isodate] ),
        -21,
        day
    )
)
