22        colored or grey-scaled, depending on the lookup table used. If the arrows
23        are colored, there are two possible coloring modes: (1) using vector data
24        or (2) using scalar data. Similarly, there are two possible types of
25        arrows: (1) using two-dimensional or (2) using three-dimensional.
