I've sifted through threads and videos trying examples, but I still seem to be stuck. Please help? DAX newbie here.
I have a data set with yearly sales with granularity by geography, device type, and another column with ~6 different technical specifications. I would like to display a dynamic waterfall chart that shows yearly changes in sales based on selected slicers/filters in the workbook.
1) Resolve in one step
=CALCULATE(SUM(Data[$]))-CALCULATE(SUM(Data[$]),PARALLELPERIOD(Data[Date],-1,YEAR))
2) Create an intermediate value for last year sales and subtract from this year's sales
LY Sales = CALCULATE(SUM(Data[$]),DATEADD(Data[Date],-1,YEAR))
VARIANCE = [$] - [LY Sales]
