SplineSeries2D Class

Represents a series view of the Spline type.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v18.2.dll

Declaration

C#

public class SplineSeries2D :
    LineSeries2D

VB.NET

Public Class SplineSeries2D
    Inherits LineSeries2D

Remarks

The SplineSeries2D class provides the functionality of a series view of the Spline type within a chart control.

In addition to the common view settings inherited from the base LineSeries2D class, the SplineSeries2D class declares the spline type specific settings, which allow you to define the style of the spline curve (SplineSeries2D.LineTension).

Note that a particular view type can be defined for a series via its Diagram.Series property.

For more information on series views of the Spline type, refer to the Spline topic.

Example

The following example demonstrates how to create a 2D Spline chart. To do this, it is necessary to assign the ChartControl.Diagram property to XYDiagram2D, and then add a SplineSeries2D object with points to the diagram’s Diagram.Series collection.

Also, this example shows how to specify SplineSeries2D.LineTension and LineSeries2D.MarkerSize properties and add a title to a chart.
