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.

This example demonstrates how to assign a secondary Y-axis to a series and uses the following classes and properties:
