Creates a new TRSDonutChartExValue instance and adds it to the Items array. The new instance is initialized with the SweepAngle, Caption, and Color parameters. The StartAngle defaults to the end angle of the last item in the collection.
Call Add to create a donut slice in the collection. The new value is placed at the end of the Items array, or, if the collection is Sorted, placed at the sorted point in the collection (based on a default value (0)).
Add returns the new donut slice value.
