<summary>Is the Waterfall Chart built directly from the data, or do I need custom calculations?</summary>

No custom calculations are needed!

The **ShowMeMore extension** handles the logic for the Waterfall Chart automatically. You simply connect your data source, and the extension does the rest — including calculating the differences between values and rendering the waterfall bars accordingly.

> ✨ Just drag in the relevant dimensions and measures — the extension takes care of the rest!
