The relationship between entropy and immobility as a function of wall position. Radius of each point was scaled to increase in proportion to the duration spent in a given state (thus the larger the dot, the longer the individual was in the given state of mobility (i.e., blue line) or immobility (redline). c, convex hull. Also note that upper means the top convex hull. Middle means the middle convex hull, bottom means bottom convex hull, and overall means the total convex hull. GIE, geometric index of entropy; IMR, immobility to mobility; m, meters.
