Example

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.
