Fig. 4. (A) Lateral (X–Y), (B) dorsal (X–Z) and (C) posterior (Z–Y) views of limb points relative to the hip. Hip position is designated by a cross. Lizard images behind graphs show position of points relative to the lizard at the start of slap. The path of each point is counterclockwise in all three plots, starting with the points outlined in black (foot and ankle) or blue (knee). Solid points indicate stance phase, open points indicate swing (i.e. recovery) phase.
