Possible ``palette`` values include:

|
|
- Name of a seaborn palette (deep, muted, bright, pastel, dark, colorblind)

- Name of matplotlib colormap

|
Calling this function with ``palette=None`` will return the current

matplotlib color cycle.
|

This function can also be used in a ``with`` statement to temporarily

Parameters
|
||
|
|
----------
|
||
|
|
palette: None, string, or sequence, optional
|
||
|
|
Name of palette or None to return current palette. If a sequence, input
|
||
|
|
colors are used but possibly cycled and desaturated.
|
||
|
|
n_colors : int, optional
|
||
|
|
Number of colors in the palette. If ``None``, the default will depend
|
||
|
|
on how ``palette`` is specified. Named palettes default to 6 colors,
|
||
|
|
but grabbing the current palette or passing in a list of colors will
|
||
|
|
not change the number of colors unless this is specified. Asking for
|
||
|
|
more colors than exist in the palette will cause it to cycle. Ignored
|
||
|
|
when ``as_cmap`` is True.
|
||
|
|
desat : float, optional
|
||
|
|
Proportion to desaturate each color by.

|
as_cmap : bool

||
|
|
If True, return a :class:`matplotlib.colors.Colormap`.

Examples
|
||
|
|
--------
|
||
|
|
|
||
|
|
Generate the default palette:
|
||
|
|
|
||
|
|
.. plot::
|
||
|
|
:context: close-figs
|
||
|
|
|
||
|
|
>>> import seaborn as sns; sns.set_theme()
|
||
|
|
>>> sns.palplot(sns.cubehelix_palette())
|
||
|
|
|
||
|
|
Rotate backwards from the same starting location:
|
||
|
|
|
||
|
|
.. plot::
|
||
|
|
:context: close-figs
|
||
|
|
|
||
|
|
>>> sns.palplot(sns.cubehelix_palette(rot=-.4))
|
||
|
|
|
||
|
|
Use a different starting point and shorter rotation:
|
||
|
|
|
||
|
|
.. plot::
|
||
|
|
:context: close-figs
|
||
|
|
|
||
|
|
>>> sns.palplot(sns.cubehelix_palette(start=2.8, rot=.1))
|
||
|
|
|
||
|
|
Reverse the direction of the lightness ramp:
|
||
|
|
|
||
|
|
.. plot::
|
||
|
|
:context: close-figs
|
||
|
|
|
||
|
|
>>> sns.palplot(sns.cubehelix_palette(reverse=True))
|
||
|
|
|
||
|
|
Generate a colormap object:
|
||
|
|
|
||
|
|
.. plot::
|
||
|
|
:context: close-figs
|
||
|
|
|
||
|
|
>>> from numpy import arange
|
||
|
|

|
||
|
|
>>> cmap = sns.cubehelix_palette(as_cmap=True)
|
||
|
|
>>> ax = sns.heatmap(x, cmap=cmap)
|
||
|
|
|
||
|
|
Use the full lightness range:
|
||
|
|
|
||
|
|
.. plot::
|
||
|
|
:context: close-figs
|
||
|
|
|

|
||
|
|
>>> ax = sns.heatmap(x, cmap=cmap)
|
||
|
|
|
||
|
|
Use through the :func:`color_palette` interface:
|
||
|
|
|
||
|
|
.. plot::
|
||
|
|
:context: close-figs
|
||
