I'm starting with a set of x and y positions that specify each vector's origin and a set of dx & dy values that specify its magnitude and direction.

The plarrows() function does not expect anything but an array of x, y
coordinates
and the u, v components of the vector. Use that instead of plvect(). 

Alternatively: define a pseudo grid with dimensions Nx1
