# Details and Options

• DateListStepPlot plots the data so that each point, including the first and last, is part of a horizontal step.
• Possible forms of datei include:
•  DateObject[…],TimeObject[…] date or time object "string" DateString specification {y,m,d,h,m,s} DateList specification {y},{y,m},{y,m,d},… shortened date list t absolute time given as a single number
• In shortened date lists, omitted elements are taken to have default values {y,1,1,0,0,0}.
• Possible forms of datespec include:
•  {start,end} dates from start to end in equal increments {start,Automatic,Δt} dates beginning with start in increments Δt {Automatic,end,Δt} dates ending with end in increments Δt start dates with increments determined by the form of start
