Use an Arrow Line plot to visualize a vector quantity as arrows on lines using a 2D Arrow Line () plot, or lines and edges using a 3D Arrow Line () plot. Add Deformation, Color Expression, or Filter subnodes as needed. For example, add a Color Expression node to color the arrows with the magnitude of the vector quantity that the arrows represent. Right-click a 2D Plot Group or 3D Plot Group to add these plots.
