smpl.plot.bar

smpl.plot.bar(x, height, width=0.8, bottom=None, *, align='center', data=None, **kwargs)[source]

Make a bar plot.

The bars are positioned at x with the given alignment. Their dimensions are given by height and width. The vertical baseline is bottom (default 0).

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

Parameters

xfloat or array-like

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

heightfloat or array-like

The height(s) of the bars.

widthfloat or array-like, default: 0.8

The width(s) of the bars.

bottomfloat or array-like, default: 0

The y coordinate(s) of the bottom side(s) of the bars.

align{‘center’, ‘edge’}, default: ‘center’

Alignment of the bars to the x coordinates:

  • ‘center’: Center the base on the x positions.

  • ‘edge’: Align the left edges of the bars with the x positions.

To align the bars on the right edge pass a negative width 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.)

labelstr or list of str, optional

A single label is attached to the resulting .BarContainer as a label for the whole dataset. If a list is provided, it must be the same length as x and labels the individual bars. Repeated labels are not de-duplicated and will cause repeated label entries, so this is best used when bars also differ in style (e.g., by passing a list to color.)

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 /gallery/statistics/errorbar_features 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: :rc:`errorbar.capsize`

The length of the error bar caps in points.

error_kwdict, optional

Dictionary of keyword arguments to be passed to the ~.Axes.errorbar method. Values of ecolor or capsize defined here take precedence over the independent keyword arguments.

logbool, default: False

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

dataindexable object, optional

If given, all parameters also accept a string s, which is interpreted as data[s] (unless this raises an exception).

Notes

Stacked bars can be achieved by passing individual bottom values per bar. See /gallery/lines_bars_and_markers/bar_stacked.
