[vtkusers] Why Axis Labels (X,Y,Z) do not show (Axes.py)?

[Kang Zhao]

Hello,

When I ran the attached Python script, the axis lables (X,Y,Z) didn't
show up. I also tried playing with
axes.GetXAxisCaptionActor2D().GetCaptionTextProperty.SetColor(1,0,0) and
SetXAxisLabelText(), but no success.

PS, the script could be found at:
http://www.cmake.org/Wiki/VTK/Examples/Python/GeometricObjects/Display/Axes.

Could anyone help to share some clue?

My environment:

OS: Windows 7 (64-bit)
Python: 2.7.7 (32 bit)
wxPython: wxPython2.8-win32-unicode-2.8.12.1-py27.exe
VTK: vtkpython-6.1.0-Windows-32bit.exe

Thanks for your help in advance.

Kang
