Thanks for your reply. However I can't see these are related to my question specifically. Would you please be more specific or post your solution workbook? Thanks
Thanks for your time. I am afraid the way you explained is too general for me hence I don't get idea. Step by step on my example would be more helpful.
Here is the brief approach.
using sets you need to track the existing customers,new customers and the customers who left the company.I have shared three visualizations that use sets.
Waterfall model what you need can be seen inthe workbooks i shared.
using the sets as filters you need to develop the final waterfall model that you need.
u can download the workbooks from the links that i shared and view the underlying data along with the approach followed to understand technically how it is done.
hope that helps.
Unfortunately I am not able to download the workbooks as my Tableau version at work is not the latest.
