The OverviewZoom event is called once the user clicks the scale buttons in the control’s overview area. The UnitScale property specifies the new selected time scale. The problem is that the control is trying to center the chart’s view once the event is performed, so actually your FirstVisibleDate call during the event is ignored. The solution is using a timer so, changing the chart’s FirstVisibleDate occurs right after finishing the event.
