[vtkusers] Save vtkChartXY to PNG

[Jothybasu Selvaraj]

Here you go

vtkSmartPointer<vtkWindowToImageFilter> windowToImageFilter =
            vtkSmartPointer<vtkWindowToImageFilter>::New();
    windowToImageFilter->SetInput(this->view->GetRenderWindow());
    windowToImageFilter->Update();


    vtkSmartPointer<vtkPNGWriter> writer =
            vtkSmartPointer<vtkPNGWriter>::New();
    writer->SetFileName("FileName");
    writer->SetInput(windowToImageFilter->GetOutput());
    writer->Write();
