## Matrix with dates and different average columns

Hello everyone,

I need your help to build a somewhat special matrix, like the one shown in the following image.  This matrix shows the last 15 months of history, the average of the last 3 months, average of the last 12 months and the average of the entire history of the data.

I think the only way to build it is with a support table to generate the desired columns, but I need the periods to be mobile.

In Table 2 of the pbix file I have solved the moving periods, but I need to add the averages columns!!!

Any help will be highly appreciated. Thanks a lot!

## Re: Matrix with dates and different average columns

@cheyzaguirre , If you are looking for the format, I doubt that. I created an idea for that

You can get month like

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))

2nd last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-2,MONTH)))
3rd last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-3,MONTH)))

4th last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-4,MONTH)))

and so on, if you need simple avg  -- Over all

Cumm Sales = CALCULATE(Average(Sales[Sales Amount]),filter(date,date[date] <=maxx(date,date[date])))
Cumm Sales = CALCULATE(Average(Sales[Sales Amount]),filter(date,date[date] <=max(Sales[Sales Date])))

Rolling

Rolling 3 = CALCULATE(Average(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],ENDOFMONTH(Sales[Sales Date]),-3,MONTH))

Rolling 12 = CALCULATE(Average(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],ENDOFMONTH(Sales[Sales Date]),-12,MONTH))

## Re: Matrix with dates and different average columns

Thank you for your answer, but it does not completely solve my problem since selecting a month filters the matrix and only shows the selected period. I need to select a month to show from the selected month back all the measurements
