Rotates a two-dimensional Cartesian coordinate system in the counterclockwise direction. Wire data to the X input to determine the polymorphic instance to use or manually select the instance.

Note This VI does not rotate points within a fixed coordinate system. This VI rotates the coordinate system about the origin.

The following illustration shows the rotation of a two-dimensional Cartesian coordinate in the counterclockwise direction by θ (–π < θ ≤ π):

Before the rotation, the coordinate of point P is (x, y). After the rotation, the coordinate of point P is (x', y'), where
