scaling factor on axis

[inventorGL]

Hello,
I am a new user of Open Inventor. I am looking for the way to draw Z axis with different scaling factor, can anyone help pointing out the solution? In my application, the z values are too small compared with the x & y values, so I need to scale the z values up in order to view them all on the scene, but I cannot find the correct parameter and function to use.
Thanks for help.

The usual solution would be an SoTransform or SoScale node. The scaleFactor field takes an SbVec3f containing scale factors for the X, Y and Z axes. A scaleFactor of 1,1,2 for example would expand the Z axis without affecting the X and Y axes.
