The Radar Chart is a built-in chart type in Excel. Radar charts, sometimes called spider charts, have one axis per category which all use the same scale. The axes of a radar chart radiate out from the center of the chart and data points are plotted on each axis using a common scale. The result is a geometric shape that shows "at-a-glance" performance across all categories.
Radar charts can be used to plot the performance of employees, athletes, products, and companies in various categories. They can be used for performance evaluations and satisfaction surveys.
