This demo shows the 3D series' Doughnut View, which is similar to the Pie View, but displays a pie with a hole of a non-zero radius.
In this demo, you're able to change pie labels visibility and position, as well as to specify whether real values are shown for each point label or for the corresponding percentage.
In addition, you may change the chart hole's radius percentage to see how this affects the chart's look.
Also, you may choose which pie slices should be exploded. For this, use the Exploded Points drop-down list.
