You could check to see if the yourGraphControl.GraphPane.XAxis(or YAxis).Scale.Min value increases, signifying a Zoom in, or decreases for a Zoom out. Or similarly, use Scale.Max...and if max decreases, it's a zoom in, and if it increases it's a zoom out.
Good Luck,

Hi everybody,
How could I know whether the zoom event is raised by a zoom in or out ?
Thanks
