Resizing Workspace Objects (Coding)
From Rave Documentation
Important Tip: When specifying axes positions and x/y/zlim properties, always use single precision variables to ensure that the on-screen display exactly matches the values you specify. Using double precision may cause the displayed objects to be off by 1 pixel, and may cause back and forth jittering during continuous resizing and animations. (This is true for all MATLAB axes, not just in Rave.)
