A percent stacked area radar chart combines the radial layout of a spider chart with percent stacking, so each category sums to 100% and you can instantly see how shares shift across parameters. Learn more in the AnyChart Radar Chart documentation.
This sample plots regional sales for Argentina, Brazil, Chile, and Colombia from 2007 to 2011 as four percent-stacked area series. The Y-axis runs from 0 to 100%, and the interactive legend lets you toggle regions; remaining percentages recalculate automatically.
