Description
For more information on how to configure this actor, see:
http://vtk.1045678.n5.nabble.com/How-to-Scale-vtkCubeAxesActor2D-td5090262.html
This was converted from Python to C++, the source I found for the Python was at:

Download and Build CubeAxesActor2D
Click here to download CubeAxesActor2D and its CMakeLists.txt file. Once the tarball CubeAxesActor2D.tar has been downloaded and extracted,
cd CubeAxesActor2D/build
If VTK is installed:
cmake ..
If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:
cmake -DVTK_DIR:PATH=/home/me/vtk_build ..
Build the project:
make
and run it:
./CubeAxesActor2D
WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
