Moving Average

Hi,   I've just started using PowerBI and I'm a massive fan of the tool. I've been trying to calculate a simple moving average for Months vs Sessions.   I've tried quite a lot of things, googling...

    Firstly you need a column of date with full date format. Then you can use calculated measure to get the expected result. Please refer to following steps.

     

    1. Create a calculated column for the date.
      FullDate =
DATE ( 2016, 'Session'[Month of the Year], 1 )
    2. Create a measure for 3 months moving average. You can change the number of months if you want.
      Moving_Average_3_Months = 
CALCULATE (
    AVERAGEX ( 'Session', 'Session'[Sessions] ),
    DATESINPERIOD (
        'Session'[FullDate],
        LASTDATE ( 'Session'[FullDate] ),
        -3,
        MONTH
    )
)
    3. Drag the Line Chart into your canvas as below.

Hi,

 

I am trying to calculate moving 3 month average and came across this post. I followed the steps exactly as mentioned in the post but no luck so far. My formula looks like this...

 

MA_3M = CALCULATE(AVERAGEX('Session', 'Session'[Sessions]), DATESINPERIOD('Session'[FullDate], LASTDATE('Session'[FullDate]),-3,MONTH))

 

While seeing the results, the Sessions and the Moving average show the same numbers....what am I missing???

 

Pleae help!

Hello,

 

I followed the steps above to create the moving average however I get an error stating that there are duplicates in my DATESINPERIOD column (this is because there are and there are supposed to be...). I was hoping it would add all the values for one day together and then average these - do you have any suggestions?

 

Thanks :)
