<br>
I'd like to create a custom interactor for vtkChartXY (inherited from<br>
vtkContextInteractorStyle), but I can't figure out how to select single<br>
points with the left click of the mouse. Once I manage to that, I would need<br>
to return the index of the selected point.<br>
<br>
This seems very straightforward to me, but I haven't seen any concrete<br>
examples.<br>
<br>
Any pointers would be greatly appreciated.<br>
<br>
