Yeah. I am using the below expression for cumulative value.
RangeSum(Above(Sum(aggr(count(MT_ID),[Issue Type],[Request Type])),0,RowNo()))/
sum(TOTAL Aggr(Count(MT_ID),[Issue Type],[Request Type])) and I am taking the top 10 by setting the max value in the presentation. Now, I want the count of Cumulative for values more than 80% to be displayed in the label of my chart.
