java.lang.Object org.opensourcephysics.display2d.VectorPlot
public class VectorPlot
VectorPlot renders a vector field in a drawing panel using arrows centered on each grid point in the GridPointData. The default representation of the vector field uses fixed length arrows to show direction and color to show magnitude.
