Transition plots for the different groups of data

The relative frequency of the fly passage at each position is plotted (red denotes a frequency above the 95% quantile value, dark blue means flies were rarely present. White indicates that none of the flies ever transitioned through this position). A. Computer-generated data (here correlated walk, but Lévy-walk transition plot is nearly identical) B. Endogenous locomotion. C. Buridan's paradigm with narrow stripes (11°). D. Buridan's paradigm with wide stripes (20°). n = 20 in each group
