RangeAreaSeriesView Class

A series view of the Range Area type.

Assembly: DevExpress.XtraCharts.v19.2.dll

Declaration

C#
VB.NET

public class RangeAreaSeriesView :
    AreaSeriesView,
    IRangeAreaSeriesView

Public Class RangeAreaSeriesView
    Inherits AreaSeriesView
    Implements IRangeAreaSeriesView

Remarks

The RangeAreaSeriesView class provides the functionality of a series view of the Range Area type within a chart control.

The RangeAreaSeriesView class inherits properties and methods from the base AreaSeriesView class which defines the common settings of area series views.

Note that a particular view type can be defined for a series via its SeriesBase.View property.

For more information on series views of the range area type, please see the Range Area Chart topic.

Example

The following example demonstrates how to create a ChartControl with a series of the RangeAreaSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.

Then, add the following code to the Form.Load event handler.
