bar
(*args, **kwargs)[source]¶Make a bar plot.
Call signatures:
bar(x, height, *, align='center', **kwargs)
bar(x, height, width, *, align='center', **kwargs)
bar(x, height, width, bottom, *, align='center', **kwargs)
The bars are positioned at x with the given align ment. Their dimensions are given by width and height. The vertical baseline is bottom (default 0).
Each of x, height, width, and bottom may either be a scalar applying to all bars, or it may be a sequence of length N providing a separate value for each bar.

Notes
The optional arguments color, edgecolor, linewidth,
xerr, and yerr can be either scalars or sequences of
length equal to the number of bars. This enables you to use
bar as the basis for stacked bar charts, or candlestick plots.
Detail: xerr and yerr are passed directly to
errorbar()
, so they can also have shape 2xN for
independent specification of lower and upper errors.
