Parameters ---------- x : (N,) array-like y : (M, N) array-like The data is assumed to be unstacked. Each of the following calls is legal:: stackplot(x, y) # where y has shape (M, N) stackplot(x, y1, y2, y3) # where y1, y2, y3, y4 have length N baseline : {'zero', 'sym', 'wiggle', 'weighted_wiggle'} Method used to calculate the baseline: - ``'zero'``: Constant zero baseline, i.e. a simple stacked plot. - ``'sym'``: Symmetric around zero and is sometimes called 'ThemeRiver'. - ``'wiggle'``: Minimizes the sum of the squared slopes. - ``'weighted_wiggle'``: Does the same but weights to account for size of each layer. It is also called 'Streamgraph'-layout. More details can be found at http://leebyron.com/streamgraph/. labels : list of str, optional A sequence of labels to assign to each data series. If unspecified, then no labels will be applied to artists. colors : list of :mpltype:`color`, optional A sequence of colors to be cycled through and used to color the stacked areas. The sequence need not be exactly the same length as the number of provided *y*, in which case the colors will repeat from the beginning. If not specified, the colors from the Axes property cycle will be used. hatch : list of str, default: None A sequence of hatching styles. See :doc:`/gallery/shapes_and_collections/hatch_style_reference`. The sequence will be cycled through for filling the stacked areas from bottom to top. It need not be exactly the same length as the number of provided *y*, in which case the styles will repeat from the beginning. .. versionadded:: 3.9 Support for list input data : indexable object, optional DATA_PARAMETER_PLACEHOLDER **kwargs All other keyword arguments are passed to `.Axes.fill_between`. Returns ------- list of `.PolyCollection` A list of `.PolyCollection` instances, one for each element in the stacked area plot.
