Line Chart Style Guide
Base line charts show the trend of values as categories change by connecting points into a line, ideal for trends and patterns. Understanding the following style options helps you create more expressive charts:
| Style Option | Effect | Suggestion |
|---|---|---|
| Smooth Curve | Makes the line more rounded and smooth | Looks better for continuous trend data |
| Data Points | Shows data nodes on the line | Can be turned off to avoid clutter when points are dense |
| Area Fill | Fills a gradient below the line | Enable to emphasize the area share |
