Exclude scrollbar from Chart Modifier click

Hello,

I created a custom chart modifier that moves a vertical line to the position where the user clicks on the scichart surface (I used OnModifierMouseUp to listen to this event), everything works well except the event fires also when the user scrolls or clicks on the scrollbar i defined for the x Axis (I guess because it is part of the surface anyway).

Is there a way to avoid the scrollbar interaction to fire this event? I’d like for it to be fired only when the user clicks directly on the data/surface rather than the scrollbar itself

Thanks a lot
