Rotating the coordinate reference frame

edit: an example of what I mean from Wolfram Alpha.
i teach high school and college physics. I am preparing a lesson for tomorrow that has a box sitting on a ramp. The students are to take the weight vector and break it into components. However, in your program, the components are rigidly tied to x and y coordinates as aligned with the edge of the screen.
Is there a way to rotate the coordinate system to align with the top of the ramp? Then deriving the downhill force and the normal force components becomes much easier. This is a much more standard way of drawing the components (x - aligned with ramp surface, y - perpendicular to ramp surface), at least in the US.
If there's no way to do it at present, I'd like to request that as a future feature.
Thanks, I'm just getting started and it looks like a fun program.
