Remarks

Series Point Labels (or series labels, for short) are used to identify particular data points within a series.

Series labels are hidden by default. To display them on a pie chart, create a PieSeriesLabel object and assign it to the PieSeries.Label property. The PieSeriesLabel class provides a set of properties you can use to specify label position and appearance:

• Position - Specifies whether series labels should be displayed inside pie segments, or they should be pained outside a pie chart and organized into two columns.
• Indent - Specifies the distance between the edge of a pie segment and its label.
• TextPattern - Specifies the text pattern for series labels.
• Style - Allows you to customize label appearance.

Example

This example demonstrates how to add labels to pie chart segments, customize the text pattern, layout and appearance of series labels.
