Hi @julien13b1 ,

I'm not clear about your requirement. Could you please provide some sample data(exclude sensitive data) and your expected result with calculation logic and specific examples? Thank you.

Just for example:

Sample data:

Col1 xxx Colxx
aa .. 11
bb .. 22

Expected result(include visual setting, calculation logic and correct values etc.)


I found some blogs about cohort analysis, you can watch or read them. Hope they can help you.
