Poincaré plot
A Poincaré plot, named after Henri Poincaré, is a graphical representation used to visualize the relationship between consecutive data points in time series to detect patterns and irregularities in the time series, revealing information about the stability of dynamical systems, providing insights into periodic orbits, chaotic motions, and bifurcations. It plays a role in controlling and predicting the system's long-term behavior, making it an indispensable tool for various scientific and engineering disciplines. It is also known as a return map. Poincaré plots can be used to distinguish chaos from randomness by embedding a data set in a higher-dimensional state space. Given a time series of the form x_t, x_{t+1}, x_{t+2}, \ldots, N, a Poincaré map in its simplest form first plots dots in a scatter plot at the positions (x_t, x_{t+1}) , then plots (x_{t+1}, x_{t+2}) , then (x_{t+2}, x_{t+3}) , and so on.
