You are right. It would appear that the scaling of the SSH axes in the 3d-plot are not correct. They have been scaled unit length. I had not picked up on this before as I had assumed they were scaled according to the axis length.
We have now fixed this for 3.04. We have also (due to user requests) increased the scaling difference on the front-back axis to further emphasize the 3d nature of the balls.
Just goes to show you that it is hard to detect everything in PATN – so thanks for picking this one up!
