Stacked Area Chart Style Guide
A stacked area chart intuitively shows each part's contribution to the whole and how it changes over time. It is ideal for illustrating total composition and share evolution. Understanding the following style options helps you create more expressive charts:
| Style Option | Effect | Suggestion |
|---|---|---|
| Smooth Curve | Makes area boundary lines more rounded and smooth | Looks better for trend data |
| Area Fill | Controls the fill and opacity of the area region | Lower opacity for multiple series to avoid overlap |
| Data Points | Shows data nodes on the line | Can be turned off when points are dense |
