Pie Chart - Selection

This sample demonstrates how to use the built in slice selection feature.

Selection mode:

This sample is designed for a larger screen size.

On mobile, try rotating your screen, view full size, or email to another device.

There are three selection modes available: single, multiple and manual. Single selection allows you to select only one slice and this is the default. Multiple select allows multiple slices to be selected at once. Manual mode is a mode added to support previous users who relied on the sliceClick event in order to programmatically select slices.
