Show values below the threshold as a percentage of selections.

[uayan]

Hello all, 

I created a visual that shows sales amount and customers. And this graph has cumulative percentage as line.

I also added a parameter slicer. When I select a value (such as % 50) it shows only values under the selection value. 

The thing what I want to do is line graph shows percentages of selected values.(Not percentages of all values)

@uayan , Try something like this

divide([Measure], calculate(sumx(filter(Values(Table[ID]) , [Cumm]<= [Whatif value]), [Measure]), allselected()) )
