ChartSegment class abstract

Creates the segments for chart series.

It has the public method and properties to customize the segment in the chart series, User can customize the calculation of the segment points by using the method calculateSegmentPoints. It has the property to store the old value of the series to support dynamic animation.

Provides the public properties color, stroke color, fill paint, stroke paint, series and old series to customize and dynamically change each segment in the chart.
