Equal waterfall in excel

Hello,

Your question is unclear.

First of all, what visual do you want to use? Do you interested in this Ultimate Waterfall?

Secondly, you always can check how data looks like as on picture below:

Thirdly, if you have unsuitable data format you always can use DAX to adjust your data into appropriate format.

Also, there is a documentation on the vizual author page.

Kind Regards,
