This would take `x` and `y` arguments _which differ by 1 (in either way)_ in length, and make a step plot that either has horizontal segments at both ends (if `len(x) == len(y) + 1`) or has vertical segments at both ends (if `len(y) == len(x) + 1`).\n\nAs far as I know, currently, to make such a plot one must manually duplicate either the first or the last value in the shorter of the two arrays, which is a bit awkward.  Additionally, `\"auto\"`-mode would make it much easier to rotate such a plot by 90° (in the \"vertical\" direction): you'd just have to switch the `x` and `y` arguments, without worrying about whether you need to change `where` or which element to duplicate.\n\nThoughts?\n","author":{"url":"https://github.com/anntzer","@type":"Person","name":"anntzer"},"datePublished":"2016-01-15T00:39:12.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":28},"url":"https://github.com/5855/matplotlib/issues/5855"}
