About Radar Charts
When to Use Radar Charts
Radar charts, also known as spider charts or star charts, are perfect for displaying multivariate data across multiple axes. They excel at showing performance metrics, skill assessments, product comparisons, and any scenario where you need to visualize how different categories relate to each other. Use radar charts when comparing multiple data series across the same set of variables, such as quality ratings, sales performance, growth metrics, efficiency scores, and market reach analysis.
