How to build a density plot. (A) On the top left-hand side, we show a typical trace of conductance of gold at 4 K during the process of breaking (red) and forming (green) a contact. (B) The top right-hand side is a zoom near 1G0 to define the values before and after the JC, G a and G b , and JOC, G c and G d . (C, D) The bottom figures show colour density plots where dark colours represent those values of conductance that appear more frequently (left for JC and right for JOC).
