[vtkusers] vtkChart in QVTKWidget

[Jothy]

Works with this

this->view->SetInteractor(this->ui->chartWidget->GetInteractor());

           this->ui->chartWidget->SetRenderWindow(this->view->GetRenderWindow());

           this->view->GetInteractor()->Initialize();

           this->view->GetInteractor()->Start();
