Filter data in previous period

I have 2 donut charts.
The one on the left shows data in the specified period the users chooses. This period is selected using a date filter in the filter pane that affects all visuals in the same page.

The chart on the right should show the previous period of the first chart. For example, if the user selected the last week, then this second chart shows data for 2 weeks ago, if the user selects March 2020 then the chart should show data for February 2020...

 

I''ve been trying to get the 2 dates selected by the user: end and begin; calculate the number of days in between; and then trying to substract those days from the begin day and filter that data but so far this is not working.

Hi  @nanci

 

Create a slicer table as below:

Table 2 = VALUES('Table'[Date])

Then create 2 measures as below:

Measure = 
var _myslicer=CALCULATETABLE(VALUES('Table 2'[Date]),FILTER('Table 2','Table 2'[Date] in FILTERS('Table 2'[Date])))
var _mindate=MINX(_myslicer,'Table 2'[Date])
var _maxdate=MAXX(_myslicer,'Table 2'[Date])
Return
CALCULATE(MAX('Table'[Value]),FILTER('Table','Table'[Date]>=_mindate&&'Table'[Date]<=_maxdate))
Measure 2 = 
var _myslicer=CALCULATETABLE(VALUES('Table 2'[Date]),FILTER('Table 2','Table 2'[Date] in FILTERS('Table 2'[Date])))
var _mindate=MINX(_myslicer,'Table 2'[Date])
var _maxdate=MAXX(_myslicer,'Table 2'[Date])
Return
CALCULATE(MAX('Table'[Value]),FILTER('Table','Table'[Date]>=_mindate-14&&'Table'[Date]<=_maxdate-14))

And you will see:

@nanci , you need to combine few calculations like for month, qtr , year like

 

Rolling 2 = CALCULATE(distinctcount(Transation[Month-Year]),DATESINPERIOD('Date'[Date],today(),-2,MONTH))

 

for week
