vtkLegendActor symbols not appearing
The vtkPolyData symbol (vtkLegendActor::SetEntry(), second argument) does not show up on screen when I compile the example code here: http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/Legend
I do see the sphere, the background and the text and the legend box correctly however. Just no square or circle symbols. I do not know why and I do not have a fix to contribute.
I am building VTK 7.0.0 on Mac OS Sierra 10.12.3 using cmake/make on the command line.
