This class is exposed as the e parameter in the AxisViewChanged and AxisViewChanging events. The AxisViewChanging event is raised just before a new view is displayed, as a result of the end-user clicking and dragging in a chart area. The AxisViewChanged event is raised just after the new view is created.
It is important to note that the position and size of a view cannot be set in the AxisViewChanged event because in this case the view is already created.
The ViewEventArgs class contains the following properties:
The ChartArea property, which is used to get the ChartArea object in which the view is being displayed. The Name property gets the name of the chart area. Other chart area properties can also be set.
The Axis property, which is used to get the Axis object with which the view is associated. To determine the type of axis, which can be X, Y, X2 or Y2, use the AxisName property. Other axis properties can also be set.
The NewPosition property, which represents the new position of a view.
The NewSize property, which represents the new size of a view.
The NewSizeType property, which represents the unit of measurement for the size of a view.
