SplineAreaSeries2D Class

Represents a series view of the Spline Area type.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v24.2.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public class SplineAreaSeries2D :
    AreaSeries2D,
    ISplineView

VB.NET

Public Class SplineAreaSeries2D
    Inherits AreaSeries2D
    Implements ISplineView

Remarks

The SplineAreaSeries2D class provides the functionality of a series view of the Spline Area type within a chart control.

In addition to the common view settings inherited from the base AreaSeries2D class, the SplineAreaSeries2D class declares spline type specific settings, which allow you to define the style of the spline curve (SplineAreaSeries2D.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 Spline Area type, refer to the Spline Area topic.

Example

The following example demonstrates how to create a 2D Spline Area chart. To do this, it is necessary to assign the ChartControl.Diagram property to XYDiagram2D, and then add two SplineAreaSeries2D objects with points to the diagram’s Diagram.Series collection.

Also, this example shows how to specify AreaSeries2D.Transparency and SplineAreaSeries2D.LineTension properties and add a title to a chart.
