Waterfall Charts
Waterfall charts show how a total is built up or broken down across categories. Each bar represents an increase or decrease, with the final bar showing the total.
They're perfect for explaining "Where did this total come from?" or "What contributed to this change?"
Waterfall charts are fantastic for financial reporting. They make it easy to see which categories are driving growth or dragging down performance.
Reading a Waterfall Chart
- Green bars represent increases (positive contributions)
- Red bars represent decreases (negative contributions)
- Blue bar at the end shows the running total
The visual tells a story: start at zero, add or subtract each category's contribution, and end at the final total.
When to Use Waterfall Charts
- Breaking down revenue by product category
- Showing profit and loss by department
- Explaining budget variances
- Visualizing how different factors contribute to a final result
