Something seems really off when looking at a shear stress plot. Example: When viewing shear stress as a vector the vectors are all over place. Forgive me if I'm wrong but these vectors actually have direction and magnitude. The thing that bothers me is the direction is determined by the setting of the type of plot. Suppose I pick TXZ. I would expect all vectors to be collinear to the YZ plane and also parallel with the Z axis. So If viewed these vectors from perpendicular to the Z axis I should see nothing but a bunch of arrows pointing directly at me or directly away from me.
