ListStepPlot

ListStepPlot[{y1,y2,…}] plots the values y1, y2, … in steps at points 1, 2, ….

ListStepPlot[{{x1,y1},{x2,y2},…}] plots the values y1, y2, … in steps at points x1, x2, ….

ListStepPlot[{data1,data2,…}] plots data from all the datai.

ListStepPlot[data,step] plots using steps specified by step.

ListStepPlot[{…,w[datai,…],…}] plots datai with features defined by the symbolic wrapper w.
