Bi Hourly Average

So I am fairly new to PowerBI and am having some issues figuring out how to do this:

 

I have a continuous stream of data that is recorded every minute. I need to be able to calculate the arithmatic average of two hours worth of data and present it alongside the actual data. In the end it would need to look something like this:

 

Ideal Data Format

 

The columns in yellow are what I'm trying to calculate. I have the rest of the data.

 

Any help would be appreciated

    OK, so that should be something along the lines of:

     

    Column = 
AVERAGEX(
     FILTER(ALL('Table'),
         [YEAR]=EARLIER([YEAR])
              && [MONTH]=EARLIER([MONTH])
              && [DAY]=EARLIER([DAY])
              && [HOUR]<=EARLIER([HOUR]) 
              && [HOUR]>=EARLIER([HOUR])-1
         ),
         [Data Point 1]
    )

    Rinse and repeat for Average 2 column using [Data Point 2] in place of [Data Point 1].
