Best for
- Showing how multiple categories evolve and flow over time
- Creating visually striking presentations of compositional change
- Reducing baseline bias found in standard stacked area charts
Avoid when
- Precise value reading is required — the shifted baseline makes values hard to read
- You have fewer than 3 categories — a simple area chart is clearer
- Your audience is unfamiliar with this chart type
