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.

Is it possible to remove the first two months? v-sihou-msft 1/1/2016 and 2/1/2016 average 100 and 125 are not the numbers I want to include in my report.

I have the same question. How can you remove the initial values, as they're not truly averages.
