I have a display and for each position I want to display 4 vectors: one to the North, South, West and East. Now I think this is easiest when I use the FlowControl facility. But I don't get the vector to the South or West when I use Display.Flow1X and Flow1Y. If I use a negative number my arrow is gone.

When I use Display.Flow1Azimuth and Display.Flow1Radial, the vectors has a wrong angle with my display.

Please help!
