Remarks

The SeriesPointAnimationActionCollection class represents a collection of SeriesPointAnimationAction objects that represent series point animation actions. Its properties and methods can be used to perform common collection operations such as adding new or deleting existing items. Individual items can be accessed using indexer notation.

A collection of animation actions can be accessed via the series point animation's SeriesPointAnimation.Actions property.

Examples

The following example demonstrates how to animate series points, so that their values are dynamically changed when displaying a chart.

To accomplish this, it is first necessary to add a trigger to a chart's Triggers collection, which will start the Year1998Animation in response to the chart's Loaded event. Then, to the ChartControl.AnimationRecords collection, add a ChartAnimationRecord with a SeriesAnimation object.
