[vtkusers] vtkChart in QVTKWidget

[Jothy]

Now, I have managed to get it rendered in QVTKWidget, but the interaction
doesn't work.

How should I start the interactor? I tried the commented line in the below
code

// Add multiple line plots, setting the colors etc

           vtkSmartPointer<vtkChartXY> chart =

             vtkSmartPointer<vtkChartXY>::New();

           chart->GetAxis(vtkAxis::LEFT)->SetTitle("yyy");

           chart->GetAxis(vtkAxis::BOTTOM)->SetTitle("xxx");

          this->view->GetScene()->AddItem(chart);

           vtkPlot *line = chart->AddPlot(vtkChart::LINE);

           line->SetInput(table, 0, 1);

           line->SetColor(0, 255, 0, 255);

           line->SetWidth(1.0);

//           this->view->GetRenderWindow()->SetMultiSamples(0);

           this->ui->chartWidget->GetRenderWindow()->AddRenderer(this->view->GetRenderer());

//           vtkRenderWindowInteractor
*chartItr=vtkRenderWindowInteractor::New();

//           this->ui->chartWidget->GetRenderWindow()->SetInteractor(chartItr);

//           this->ui->chartWidget->GetInteractor()->Initialize();

//           this->ui->chartWidget->GetInteractor()->Start();

             this->ui->chartWidget->show();


Thanks
