matplotlib.axes.Axes.barh¶

Axes.barh(y, width, height=0.8, left=None, *, align='center', **kwargs)[source]¶

Make a horizontal bar plot.

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

Many parameters can take either a single value applying to all bars or a sequence of values, one for each bar.

Parameters:

yfloat or array-like

The y coordinates of the bars. See also align for the alignment of the bars to the coordinates.

widthfloat or array-like

The width(s) of the bars.

heightfloat or array-like, default: 0.8

The heights of the bars.

leftfloat or array-like, default: 0

The x coordinates of the left sides of the bars.

align{'center', 'edge'}, 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:

BarContainer: Container with all the bars and optionally errorbars.

Other Parameters:

colorcolor or list of color, optional

The colors of the bar faces.

edgecolorcolor or list of color, optional

The colors of the bar edges.

linewidthfloat or array-like, optional

Width of the bar edge(s). If 0, don't draw edges.

tick_labelstr or list of str, optional

The tick labels of the bars. Default: None (Use default numeric labels.)

xerr, yerrfloat 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.

ecolorcolor or list of color, default: 'black'

The line color of the errorbars.

capsizefloat, default: rcParams["errorbar.capsize"] (default: 0.0)

The length of the error bar caps in points.

error_kwdict, optional

Dictionary of kwargs to be passed to the errorbar method. Values of ecolor or capsize defined here take precedence over the independent kwargs.

logbool, default: False

If True, set the x-axis to be log scale.
