AFAIK, you can set the line thickness, color and opacity, but the vtkChart
plots are drawn using a 2D context scene, not the usual VTK 3D rendering, so
you can't render them as tubes. (Also, because they are built for speed,
they use OpenGL line and sprite drawing, and as far as I've seen you can't
apply anti-aliasing.)

There are other ways of turning your data into tubes and using the standard
VTK rendering, I think, if you really want that, though. (But haven't tried
it myself.)
