Are you trying to visualize motion in 2 different planes? If so, I do not believe you will be able to accomplish anything that looks like the actual movement, as the angular perspective will not be correct. The input can be any engineering unit, and you define the center of rotation, the position at each end, and corresponding register minimum and maximum values. The rotation is depicted in linear format. Floating point is okay. Sometimes, I do a course depiction of movement using a series of images with visualization animation to increment them. That may not be practical for you but it's another option.

It's all okay as long as it's okay.
