Illustration of the process for constructing multiplex recurrence network based on multidimensional time series. Subgraph (a) displays the original time series from three dimensions, marked as A, B, and C. The recurrence networks from the time series with a threshold of ε, yielding a recurrence rate of 0.05, are shown in subgraph (b). The multiplex recurrence network with edges weighted by inter-layer mutual information is displayed in subgraph (c)
