[vtkusers] vtkChartXY picking

[mbcx9rb9]

Hi all,

I'd like to create a custom interactor for vtkChartXY (inherited from
vtkContextInteractorStyle), but I can't figure out how to select single
points with the left click of the mouse. Once I manage to that, I would need
to return the index of the selected point.

This seems very straightforward to me, but I haven't seen any concrete
examples.

Any pointers would be greatly appreciated.

Regards,
Richard
