matplotlib.container

class matplotlib.container.BarContainer(*args, **kwargs) [source]

Container for the artists of bar plots (e.g. created by Axes.bar).

The container can be treated as a tuple of the patches themselves. Additionally, you can access these and further parameters by the attributes.

Attributes:	`patcheslist of Rectangle` The artists of the bars. `errorbarNone or ErrorbarContainer` A container for the error bar artists if error bars are present. None otherwise.

class matplotlib.container.Container(*args, **kwargs) [source]

Base class for containers.

Containers are classes that collect semantically related Artists such as the bars of a bar plot.

add_callback(self, func)

Add a callback function that will be called whenever one of the Artist's properties changes.

Parameters:	`funccallable` The callback function. It must have the signature: def func(artist: Artist) -> Any where artist is the calling `Artist`. Return values may exist but are ignored.
Returns:	int The observer id associated with the callback. This id can be used for removing the callback with `remove_callback` later.

set_label(self, s)

Set a label that will be displayed in the legend.

Parameters:	`sobject` s will be converted to a string by calling `str`.

class matplotlib.container.ErrorbarContainer(*args, **kwargs) [source]

Container for the artists of error bars (e.g. created by Axes.errorbar).

The container can be treated as the lines tuple itself. Additionally, you can access these and further parameters by the attributes.

Attributes:	`linestuple` Tuple of `(data_line, caplines, barlinecols)`. data_line : `Line2D` instance of x, y plot markers and/or line. caplines : tuple of `Line2D` instances of the error bar caps. barlinecols : list of `LineCollection` with the horizontal and vertical error ranges. `has_xerr, has_yerrbool` `True` if the errorbar has x/y errors.

class matplotlib.container.StemContainer(*args, **kwargs) [source]

Container for the artists created in a Axes.stem() plot.

The container can be treated like a namedtuple (markerline, stemlines, baseline).

Attributes:	`markerlineLine2D` The artist of the markers at the stem heads. `stemlineslist of Line2D` The artists of the vertical lines for all stems. `baselineLine2D` The artist of the horizontal baseline.

Parameters:	`markerline_stemlines_baselinetuple` Tuple of `(markerline, stemlines, baseline)`. `markerline` contains the `LineCollection` of the markers, `stemlines` is a `LineCollection` of the main lines, `baseline` is the `Line2D` of the baseline.
