Notes

The Vector plot is also called Quiver plot.

The leftmost Y column controls the Y coordinate of the vector tail (by default). The second Y column determines the angle of the vector. The angle is measured counterclockwise from a line parallel to the X axis, bisecting the vector. The third Y column controls the vector length in units of points. The Plot Details dialog box provides a control to scale the length of the vector (Format: Plot).
