Line Chart Style Guide
A line chart uses lines connecting data points to show how values change over time, ideal for trend analysis and multi-series comparison. Understanding the following style options makes your chart more expressive:
| Style Option | Purpose | Recommendation |
|---|---|---|
| Smooth Curve | Smooth the turns of the line | Looks more natural for smooth trends |
| Area Fill | Fill a gradient region below the line | Turn it on to emphasize comparisons between series |
| Data Points | Show dot markers at data positions | Reduce size when points are dense |
