I have a 2D bar chart. Each bar on the bar chart has an annotation. Each annotation is positioned directly on top of each horizontal bar.
 
	I also have tool tips configured on each bar.
 
	If I rollover/rollout the mouse on an annotation, it prevents any rollover/rollout events firing on the underlying bar. The tool tip disappears. The mouse event is processed by the annotation only.
 
	Is there a way I can pass the rollover/rollout event through to the data plot, so that the tool tips still work?
 
	Thanks.
