Unfortunately, the above example is incomplete, and replicating it has been<br>
unsuccessful. Below is what I have so far: a QVTKOpenGLWidget sharing a<br>
vtkGenericOpenGLRenderWindow with a vtkContextView. <br>
<br>
Any advice?<br></blockquote><div><br></div><div>I wrote a number of tests for the charts, such as this one which is fully functional with image regression testing,</div><div><br></div><div><a href="https://github.com/Kitware/VTK/blob/master/Charts/Core/Testing/Cxx/TestHistogram2D.cxx">https://github.com/Kitware/VTK/blob/master/Charts/Core/Testing/Cxx/TestHistogram2D.cxx</a></div><div><br></div><div>It shows all elements including using a vtkImageData in the plot.
