However, when I use it with Amount measure in Chart, it is only considering Jan month specific amount in '1st Month' bucket and not in next two buckets.
Basically, output is required in below form
Month Bucket
Amount
1st Month
10
Quarter
60
Half Year
210
It should calculate amount for each bucket considering earlier month(s) as
1st Month = 10
Quarter = 10+20+30 i.e. 60
Half Year = 10+20+30+40+50+60 i.e. 210
May I know what are changes required in calculating Amount measure/expression?
you need to create multiple columnsfor each 1st month ,Quarter and Half year or still you want single column you need to duplicate the rows like below ,
