Doughnut Series
Doughnut Series is the hollow-center version of Pie Series. The center area can show a total value, a percentage, or a heading; preferred when a single KPI emphasis is needed.
Prerequisite
This chart type can only be selected in step 2 of the Cartography Widget Wizard. If you have not started widget creation, start the wizard first; an appropriate Compass record is also required.
