is something like this possible to create in tableau?
IF ISNULL(attr([Task Name])) THEN
[Drill Down] = "Task"
AVG([Task Duration (Seconds)])/[Time Type]
AVG[Workflow Duration (Seconds)])/[Time Type]
[Drill Down] = "WorkFlow"
Yeah its possible in tableau. Need more explaination regarding the dimensions and measure which you've used in the IF..ELSE..END statement. It'll be more helpful If you share workbook with dummy data.
