is as below - it is the view's renderwindow that needs to be set to my
renderwindow, not the other way around as shown for the Qt widget in the
documentation - specifically:
>         view->SetRenderWindow(GetRenderWindow());
>         view->SetInteractor(GetInteractor());

Glad it worked out. I don't know why the docs says otherwise. Perhaps it's
old information.

and connecting Mapper / Actor / Renderer / Interactor etc. and connecting
the renderwindow to the renderer.  The visualization is shown in my window
and the display responds to mouse and keyboard actions.    What do I need
to do in order to do the same with VTK Charting ? The interacting seems to
have been initialized and started as I can put a break in the program and
step through the Interactor code for mouse events.
