(a) Crude oil price series, where the green line represents the stable period and the red line represents the sharp period. (b) evolution of the adjacency matrix of LPHVGs associated to the random series extracted from a uniform distribution. (c) Evolution of the adjacency matrix of LPHVGs associated to crude oil price series. (d) Mean degree of the LPHVGs associated to random series, crude oil price series and the predicted theoretical value. (e) Mean clustering coefficient of the LPHVGs associated to random series, crude oil price series and the theoretical value. (f) Mean path length of the LPHVGs associated to random series, crude oil price series and the theoretical value. (g) Distance distribution of random series. (h) Distance distribution of crude oil price series. (i) Correlation index distribution of crude oil price series.
