Problem with Moving Annual Total

Im looking after the Rolling Year.

In my Datetable I've created columns which yield in TRUE if a certain condition is fullfilled. This columns are dynamic, since I do not want to change the filter context each time when refreshed. For example the column for last year is calculated as follows:

LastYear = if(Year(DATEADD('Calendar'(Date);12;MONTH))=Year(Today());"TRUE")

Now I want to do a visual with lines or stocked columns for each product subcategorie, which display as well the rolling year started in the month before. In the datetable this is created by:

LYM-1 = if(Year(DATEADD('Calendar'(Date);13;MONTH))=Year(Today());"TRUE")

Based on this columnes I can achieve the value for the period in question. The measures look like:

LYSales = Calculate(Sum(Sales(SalesAC));Filter(all('Calendar');'Calendar'(LastYear)="TRUE"))

LYM-1Sales = Calculate(Sum(Sales(SalesAC);Filter(all('Calendar');'Calendar'(LYM-1)="TRUE"))

But I'm not able to visualize this in a stacked column or line chart, where each column, respective each datapoint on the line represents a rolling year(eg. LYSales and LYM-1Sales). Do you have any ideas how to solve this problem?

Thanks for your help.
