So, you plan to select two months or are you going to select on the quarter? If you select quarter, what would the calculation be as there are three months in both the quarter? Also... what is your current expression? and what is your dimension in the chart?
I want to select two-quarter FYQ-1 and FYQ-1 and each quarter has 3 months. In measures I use set analysis that subtract the value of fyq-2 to fyq-1 but that is not automated I want that in future if I select fyq-3 and fyq-2 them it automatically subtract fyq-3 to fyq-2 and so on.
thats is my problem what should I add in dimension right now the there is no dimension it is "Getcurrentselection()"
