I was able to do this by drawing lines and points on a graph, but I imagine there is a better way. 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. > > Thanks, > Hazen > 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 Regards, Arjen
