matplotlib.pyplot.barh

matplotlib.pyplot.barh(*args, **kwargs) [source]

Make a horizontal bar plot.

Call signatures:

bar(y, width, *, align='center', **kwargs)
bar(y, width, height, *, align='center', **kwargs)
bar(y, width, height, left, *, align='center', **kwargs)

The bars are positioned at y with the given align. Their dimensions are given by width and height. The horizontal baseline is left (default 0).

Each of y, width, height, and left 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.

Parameters:	y : scalar or array-like The y coordinates of the bars. See also align for the alignment of the bars to the coordinates. width : scalar or array-like The width(s) of the bars. height : sequence of scalars, optional, default: 0.8 The heights of the bars. left : sequence of scalars The x coordinates of the left sides of the bars (default: 0). align : {'center', 'edge'}, optional, default: 'center' Alignment of the base to the y coordinates*: 'center': Center the bars on the y positions. 'edge': Align the bottom edges of the bars with the y positions. To align the bars on the top edge pass a negative height and align='edge'.
Returns:	container : BarContainer Container with all the bars and optionally errorbars.
Other Parameters:	color : scalar or array-like, optional The colors of the bar faces. edgecolor : scalar or array-like, optional The colors of the bar edges. linewidth : scalar or array-like, optional Width of the bar edge(s). If 0, don't draw edges. tick_label : string or array-like, optional The tick labels of the bars. Default: None (Use default numeric labels.) xerr, yerr : scalar or array-like of shape(N,) or shape(2,N), optional If not None, add horizontal / vertical errorbars to the bar tips. The values are +/- sizes relative to the data: scalar: symmetric +/- values for all bars shape(N,): symmetric +/- values for each bar shape(2,N): Separate - and + values for each bar. First row contains the lower errors, the second row contains the upper errors. None: No errorbar. (default) See Different ways of specifying error bars for an example on the usage of xerr and yerr. ecolor : scalar or array-like, optional, default: 'black' The line color of the errorbars. capsize : scalar, optional The length of the error bar caps in points. Default: None, which will take the value from rcParams["errorbar.capsize"]. error_kw : dict, optional Dictionary of kwargs to be passed to the errorbar method. Values of ecolor or capsize defined here take precedence over the independent kwargs. log : bool, optional, default: False If True, set the x-axis to be log scale.

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.
