public Boolean History {get; set;}
Remarks
Zoom Pen and Brush may be modified. The HIstory property allows an optional historical recording of Chart zoom-ins when true, so that zoom-out is in their reverse sequence.
Example:
tChart1.Zoom.Pen.Color = Color.White ;
tChart1.Zoom.History = true;
tChart1.Zoom.Brush.Color = Color.Blue;
