Rolling average without dates

I found out how to do it minutes after I posted on the forum. I found a calculated column code which works exactly how I want it. 

Column = 
var my_index = 'Table'[Index]
var my_result = 
    AVERAGEX(
        FILTER(
            'Table',
            'Table'[Index] > my_index-5 &&
            'Table'[Index] <= my_index
        ), 'Table'[Parameter]
    )
RETURN my_result

This makes a rolling average of the last 5 parameters. You will need to create an index column, but that's the only thing you should need to create in order to graph a rolling average.
