Chaotic Rössler system (a = 0.165): (a) short segments of time series (x, y, z), (b) temporal variation of order patterns corresponding to the particular time window of (a,c) ordinal pattern transition network with self-loops, ${\mathscr{H}}_O=2.283$, and (d) without self-loops, ${\mathscr{H}}_T=2.585$, where the transition route π ₁ → π ₅ → π ₆ → π ₈ → π ₄ → π ₃ → π ₁ is observed. The values on links represent the corresponding transition frequencies of the ordinal patterns. Note that N = 500000 data points are used in obtaining (c,d).
