IndexOutOfBoundsException when TooltipEnabled = true

set TooltipEnabled = true

add 0th to 100th point to the graph.
remove 0th to 50th point from graphs datasource
add 101st to 150th point to the graph

Now, when you click on 101st to 150th point you will get Java.Lang.IndexOutOfBoundsException

Also, for chart.SelectionChanged event one can get P1.SelectedDataPointIndex bigger than the count of points in the graph if some points were removed previously.

Best regards
