Radar charts compare multiple values around a shared circular axis. They are useful when viewers need to compare patterns across the same set of categories rather than inspect exact values in a table.
When to use radar charts
Use radar charts for:
- Scorecards with the same dimensions across teams, products, regions, or customers
- Multi-metric comparisons where the overall shape matters
- Capability, quality, risk, or performance profiles
- Comparing a small number of series across a fixed set of categories
SQL shape
Return one column for the radar category and one or more numeric columns for the values to plot.

Radar charts support settings for:
- Polygon or circular grid style
- Radial lines and radius axis visibility
- Axis and radius value formatting
- Custom axis minimum and maximum values
- Normalized data
- Fill opacity, stroke width, dots, and dot size
- Labels, legends, tooltips, animation, and chart colors
Tips
- Keep the number of radar dimensions small enough to scan.
- Use a consistent category order across dashboards.
- Use custom axis bounds when viewers need comparable scales across charts.
- Use bar or table charts when exact rank or precise value comparison matters more than the overall shape.
