What is a radar chart?
A radar chart displays several quantitative variables on axes that radiate from one center. Connecting the values creates a shape that helps readers compare broad profiles, such as product attributes, team skills, or performance dimensions.
Create a useful radar chart
- Put the metric names in the first column.
- Add one numeric column for each item you want to compare.
- Keep every metric on the same direction and preferably the same scale.
- Use transparent or contrasting colors when multiple shapes overlap.
When to choose another chart
Radar charts support holistic pattern recognition but make precise comparisons difficult. When readers must identify exact differences metric by metric, a grouped bar chart is usually clearer.
Frequently asked questions
What is another name for a radar chart?
Radar charts are also called spider charts, web charts, star plots, or polar charts.
Should every axis use the same scale?
Usually yes. A shared range makes the shape interpretable and prevents one axis from receiving accidental emphasis.
How many metrics should I include?
A modest set of five to ten axes is usually easiest to read. Too many axes and overlapping series quickly become cluttered.
