Represents the secondary Y-axis within a 2D chart type.
Namespace : DevExpress.Xpf.Charts
Assembly : DevExpress.Xpf.Charts.v25.2.dll
NuGet Package : DevExpress.Wpf.Charts
public class SecondaryAxisY2D :
AxisY2D
Public Class SecondaryAxisY2D
Inherits AxisY2D
The following members return SecondaryAxisY2D objects:
The SecondaryAxisY2D class represents the secondary axis of values (Y-axis) within a chart control. It inherits properties and methods from its base AxisY2D class, which implements the common X-axes functionality.
The collection of the SecondaryAxisY2D objects is represented by the SecondaryAxisYCollection class, which is returned by the XYDiagram2D.SecondaryAxesY property.
The secondary X-axis is represented by the SecondaryAxisX2D class.
For more information, refer to Primary and Secondary Axes.
This example demonstrates how to assign a secondary Y-axis to a series and uses the following classes and properties:
| Symbol | Description |
|---|---|
| XYDiagram2D.SecondaryAxesY | Gets the collection of secondary Y-axes. |
SecondaryAxisY2D | Represents the secondary Y-axis within a 2D chart type. |
| XYSeries2D.AxisY | Specifies the Y-axis (or its View Model) that measures a series. |
