Radar charts display statistics along spokes that radiate from the center of the chart.
Multiple charts are often stacked on top of one another, and circular reference lines can be displayed to show the relative magnitude of the statistical values that are represented in each chart. Stacking charts around a center point reveals the interrelationships among data measures and facilitates data comparisons. For example, radar charts are useful for comparing the same measures across different test cases, or for evaluating the results of market research studies. All rights reserved.
