A Radar chart is used to display circular visual representation of a 2-dimensional data. One can think of it as a circular XY chart. These charts represent each variable on a separate axis, which are arranged radially at equal distances from each other. Each of these axes share the same tick marks and scale. The data for each observation is plotted along these axis and then joined to form a polygon. Radar charts are generally used for analyzing performance or comparing values such as revenue and expense.

GcExcel supports the following types of radar charts.
