We need to put a toggle button in Dashboard. There would be two text Cumulative and Non Cumulative. Depending on the selection it will show either Cumulative chart or Non Cumulative chart. The calculation is only difference between two Chart.
I could do this in Qlikview using variable however in Qlik sense I am not able to do.
Use that master item dimension as a dimension in your chart and create a filter pane with the field 'Name' from the inline table.
Selecting a name in the filter pane will make the chart change, as there is no way to limit the selection to just one it is also wise to add a calculation condition on the chart.Calulation condition can be found under Add-ons > Data handling, I use getselectedcount(Name)=1
