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.

Thank you so much for the responses.

 

v-sihou-msft Thank you so much.

 

sdjensen I took your advice and looked into creating its own date table, extremely useful!

 

I used this code to create a 10 day Simple Moving average:

Moving_Average_3_Months = 
CALCULATE (
    AVERAGEX ( 'All Web Site Data', 'All Web Site Data'[Sessions] ),
    DATESINPERIOD (
        'Table123'[DateKey],
        LASTDATE ( 'Table123'[DateKey] ),
        -10,
        DAY
    )
)

The drill down feature doesn't seem to want to work for me. Should I simple create my own hierarchy for this?
