Questions about vtkCubeAxesActor

Hello, I have been learning VTK for one year. I met some questions about the vtkCubeAxesActor.

  1. I have tried to use SetUserTransform, SetScale, SetPosition and RotateX, but these methods did not work.
  2. Abont font,I have tried to use SetFontFamily, SetFontFile and SetFontSize, but these methods did not work.

so i want to know that these are bugs or vtkCubeAxesActor does not support or my use problem.
