public Boolean Zoomed {get; set;}
Remarks
Run-time only.
The Zoomed property determines if Chart axis scales do not fit all Chart points.
It is set to true when users's apply zoom or scroll to the Chart using the mouse at run-time.
The Zoom.Undo method sets the Zoomed property to false and resets the axis scales to fit all Series points.
The default value is true, meaning no zoom or scroll has been applied to the chart after it has been displayed for first time.
