## calculting rolling wages / sales ratio (3mth)

I have a couple of tables linked like below

Dates

so line has [sales]

Dates
links to GLTransactions (on field [trans_date])
GLTransactions has [wages]

I am trying to get a measure for a graph which is

3 mths rolling average wages / 3 mth rolling average sales

which I would just graph against time (the date on the dates table)

and where should the measure exist? on the date table?

@ScottPat , With help from date table you have to create measure like

3 Month Avg = CALCULATE(AverageX(Values('Date'[MONTH Year]),calculate(Sum('Table'[Value])))
,DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-3,MONTH))
