- Axes.violinplot(dataset, positions=None, vert=True, widths=0.5, showmeans=False, showextrema=True, showmedians=False, quantiles=None, points=100, bw_method=None, *, data=None)#
Make a violin plot.
Make a violin plot for each column of dataset or each vector in sequence dataset. Each filled area extends to represent the entire data range, with optional lines at the mean, the median, the minimum, the maximum, and user-specified quantiles.
- datasetArray or a sequence of vectors.
The input data.
- positionsarray-like, default: [1, 2, ..., n]
The positions of the violins. The ticks and limits are automatically set to match the positions.
- vertbool, default: True.
If true, creates a vertical violin plot. Otherwise, creates a horizontal violin plot.
- widthsarray-like, default: 0.5
Either a scalar or a vector that sets the maximal width of each violin. The default is 0.5, which uses about half of the available horizontal space.
- showmeansbool, default: False
True, will toggle rendering of the means.
- showextremabool, default: True
True, will toggle rendering of the extrema.
- showmediansbool, default: False
True, will toggle rendering of the medians.
- quantilesarray-like, default: None
If not None, set a list of floats in interval [0, 1] for each violin, which stands for the quantiles that will be rendered for that violin.
- pointsint, default: 100
Defines the number of points to evaluate each of the gaussian kernel density estimations at.
- bw_methodstr, scalar or callable, optional
The method used to calculate the estimator bandwidth. This can be 'scott', 'silverman', a scalar constant or a callable. If a scalar, this will be used directly as
kde.factor. If a callable, it should take a
matplotlib.mlab.GaussianKDEinstance as its only parameter and return a scalar. If None (default), 'scott' is used.
- dataindexable object, optional
If given, the following parameters also accept a string
s, which is interpreted as
data[s](unless this raises an exception):
A dictionary mapping each component of the violinplot to a list of the corresponding collection instances created. The dictionary has the following keys:
bodies: A list of the
PolyCollectioninstances containing the filled area of each violin.
LineCollectioninstance that marks the mean values of each of the violin's distribution.
LineCollectioninstance that marks the bottom of each violin's distribution.
LineCollectioninstance that marks the top of each violin's distribution.
LineCollectioninstance that marks the centers of each violin's distribution.
LineCollectioninstance that marks the median values of each of the violin's distribution.
LineCollectioninstance created to identify the quantile values of each of the violin's distribution.
