How to limit Data in Waterfall Chart with Dropdown Menu?

Hello, I have a dropdown menu that shows"unique values in column" from an excel sheet. (name: "sourcemarketsdriver" data type: string). Now I want to apply the choice made there as a filter to my waterfall chart, so that it only shows values that match the calumn value choosen in the dropdown menu. I would be very happy for any suggestions on how to solve this. Thanks! Lina
