Remarks
The SecondaryAxisX2D class represents the secondary axis of arguments (X-axis) within a chart control. It inherits properties and methods from its base AxisX2D class, which implements the common X-axes functionality.
The collection of the SecondaryAxisX2D objects is represented by the SecondaryAxisXCollection class, which is returned by the XYDiagram2D.SecondaryAxesX property.
The secondary Y-axis is represented by the SecondaryAxisY2D class.
