matplotlib.pyplot.stem

matplotlib.pyplot.stem(*args, **kwargs)

Create a stem plot.

Call signatures:

stem(y, linefmt='b-', markerfmt='bo', basefmt='r-')
stem(x, y, linefmt='b-', markerfmt='bo', basefmt='r-')

A stem plot plots vertical lines (using linefmt) at each x location from the baseline to y, and places a marker there using markerfmt. A horizontal line at 0 is plotted using basefmt.

If no x values are provided, the default is (0, 1, …, len(y) - 1)

Return value is a tuple (markerline, stemlines, baseline). See StemContainer
