SplineAreaStackedSeries2D Class
Represents a series view of the Stacked Spline Area type.
Namespace: DevExpress.Xpf.Charts
Assembly: DevExpress.Xpf.Charts.v19.1.dll
Declaration
public class SplineAreaStackedSeries2D :
AreaStackedSeries2D,
IStackedSplineView,
ISplineView,
IStackedView,
IGeometryStripCreatorRemarks
The SplineAreaStackedSeries2D class provides the functionality of a series view of the Stacked Spline Area type within a chart control.
In addition to the common view settings inherited from the base AreaStackedSeries2D class, the SplineAreaStackedSeries2D class declares spline type specific settings, which allow you to define the style of the spline curve (SplineAreaStackedSeries2D.LineTension).
Note that a particular view type can be defined for a series using its Diagram.Series property.
For more information on series views of the Stacked Spline Area type, refer to the Stacked Spline Area topic.
Example
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.
