Signature de la méthode violin
def violin(self, vpstats, positions=None, *, vert=None, orientation='vertical', widths=0.5, showmeans=False, showextrema=True, showmedians=False, side='both')
Description
help(Axes.violin)
Draw a violin plot from pre-computed statistics.
Draw a violin plot for each column of *vpstats*. Each filled area
extends to represent the entire data range, with optional lines at the
mean, the median, the minimum, the maximum, and the quantiles values.
Parameters
----------
vpstats : list of dicts
A list of dictionaries containing stats for each violin plot.
Required keys are:
- ``coords``: A list of scalars containing the coordinates that
the violin's kernel density estimate were evaluated at.
- ``vals``: A list of scalars containing the values of the
kernel density estimate at each of the coordinates given
in *coords*.
- ``mean``: The mean value for this violin's dataset.
- ``median``: The median value for this violin's dataset.
- ``min``: The minimum value for this violin's dataset.
- ``max``: The maximum value for this violin's dataset.
Optional keys are:
- ``quantiles``: A list of scalars containing the quantile values
for this violin's dataset.
positions : array-like, default: [1, 2, ..., n]
The positions of the violins; i.e. coordinates on the x-axis for
vertical violins (or y-axis for horizontal violins).
vert : bool, optional
.. deprecated:: 3.10
Use *orientation* instead.
If this is given during the deprecation period, it overrides
the *orientation* parameter.
If True, plots the violins vertically.
If False, plots the violins horizontally.
orientation : {'vertical', 'horizontal'}, default: 'vertical'
If 'horizontal', plots the violins horizontally.
Otherwise, plots the violins vertically.
.. versionadded:: 3.10
widths : float or array-like, default: 0.5
The maximum width of each violin in units of the *positions* axis.
The default is 0.5, which is half available space when using default
*positions*.
showmeans : bool, default: False
Whether to show the mean with a line.
showextrema : bool, default: True
Whether to show extrema with a line.
showmedians : bool, default: False
Whether to show the median with a line.
side : {'both', 'low', 'high'}, default: 'both'
'both' plots standard violins. 'low'/'high' only
plots the side below/above the positions value.
Returns
-------
dict
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 `~.collections.PolyCollection`
instances containing the filled area of each violin.
- ``cmeans``: A `~.collections.LineCollection` instance that marks
the mean values of each of the violin's distribution.
- ``cmins``: A `~.collections.LineCollection` instance that marks
the bottom of each violin's distribution.
- ``cmaxes``: A `~.collections.LineCollection` instance that marks
the top of each violin's distribution.
- ``cbars``: A `~.collections.LineCollection` instance that marks
the centers of each violin's distribution.
- ``cmedians``: A `~.collections.LineCollection` instance that
marks the median values of each of the violin's distribution.
- ``cquantiles``: A `~.collections.LineCollection` instance created
to identify the quantiles values of each of the violin's
distribution.
