(color online) Histograms of the probabilities of six typical current signals corresponding to Figs. 3(a)–3(f) respectively. The green histograms with vertical stripes represent the probabilities of six current signal in the micro-channel with 5- diameter, and the orange histograms with horizontal stripes are for the 10- diameter micro-channel.
