DateListStepPlot

DateListStepPlot[{{date1, y1}, {date2, y2}, …}] plots the values yi in steps at a sequence of dates.

DateListStepPlot[{y1, y2, …}, datespec] plots the values yi in steps with dates at equal intervals specified by datespec.

DateListStepPlot[tseries] plots the time series tseries.

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

DateListStepPlot[…, step] plots using steps specified by step.

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