A couple of changes to the number lines that I would like you to check:
* I added two tiles: "transform to pixel" and "transform to graph" (the names could be improved but I didn't know how to name them). This tiles take a number as a parameter and return it transformed to the other coordinate system. It's a general way of using the number lines and I think it could be very useful.
* I changed "x on graph" and "y on graph" to take into account the object's rotation center. However, I could have messed up with this and it could have undesired side effects, so testing would be needed.

I attached a project with these features.
