The following example demonstrates how to create a 2D Stacked Spline Area chart. To do this, it is necessary to assign the ChartControl.Diagram property to XYDiagram2D, and then add three SplineAreaStackedSeries2D objects with points to the diagram’s Diagram.Series collection.

Also, this example shows how to specify AreaStackedSeries2D.Transparency and SplineAreaStackedSeries2D.LineTension properties and add a legend to a chart.
