Thanks Marcus.<div><br></div><div>The code I had somehow disabled mouse interactions - I wasn't able to zoom or interact with the renderWindow that I created - however using your code snippet it worked out. (instead of creating a new QVTKInteractor, use the one from QVTKWidget). Not sure why though.</div>

As long as you are programming in C++ I think you can follow the examples in [vtksource]/Examples/Infovis/Cxx -- there they have things like EasyView that put a vtkGraphLayoutView into a QVTKWidget. I haven't tried this with the Charts specifically, but since vtkContextView is also a vtkRenderView, hopefully you can do the same thing:<br>
<br>
// Graph View needs to get my render window<br>
this->GraphView->SetInteractor(this->ui->vtkGraphViewWidget->GetInteractor());<br>
this->ui->vtkGraphViewWidget->SetRenderWindow(this->GraphView->GetRenderWindow());<br>
<br>
(The reason I say that hopefully you're using C++ is that I can't get this to work with the Python wrappers and PyQt4...)<br>

How would I get this embedded into a QWidget? I've been using QVTKWidget previously but I don't think I can just put the renderer from the context view into the qvtkwidget?<br>
