filtering results in set analisys

[ecabanas]

Hi all,

I'm doing a vertical graph bar that shows the number of customer per category. For example if I select 2019 and October, I'll have the results for last 12 months.

Count({<[SalesId]={"PV0***"},CalendarYear_C =,CalendarMonthName_C=,CalendarMonthAndYear_C={">=$(=addmonths(max(CalendarMonthAndYear_C),-12)) <=$(=Max(CalendarMonthAndYear_C))"}>} Custaccount)

But in the the graph I want to show the numbers in sections, number of customer that only bough once in this 12 months, between 2 and 9 and more than 9

I don't know how to do that graph,

Thanks for your help
