Gets the Axis object that a scrollbar belongs to.
Axis of the event.

Syntax

Visual Basic (Declaration)
Public ReadOnly Property Axis As Axis

Visual Basic (Usage)	Copy Code
`Dim instance As ScrollBarEventArgs Dim value As Axis value = instance.Axis`

C#
public Axis Axis {get;}

Return Value

An object of type Axis that represents the axis that the scrollbar belongs to.

Example

In this example we override the default behavior when the user clicks on the reset button. Normally clicking on the reset button will result in the previous view being displayed, but using the AxisScrollBarClicked event we reset the view to its original state (i.e. no zooming). We only do this for the X axis of a chart area named Default.
