Fonction get_cmap - module matplotlib.pyplot

Signature de la fonction get_cmap

def get_cmap(name=None, lut=None) 

Description

get_cmap.__doc__

    Get a colormap instance, defaulting to rc values if *name* is None.

    Colormaps added with :func:`register_cmap` take precedence over
    built-in colormaps.

    Notes
    -----
    Currently, this returns the global colormap object, which is deprecated.
    In Matplotlib 3.5, you will no longer be able to modify the global
    colormaps in-place.

    Parameters
    ----------
    name : `matplotlib.colors.Colormap` or str or None, default: None
        If a `.Colormap` instance, it will be returned. Otherwise, the name of
        a colormap known to Matplotlib, which will be resampled by *lut*. The
        default, None, means :rc:`image.cmap`.
    lut : int or None, default: None
        If *name* is not already a Colormap instance and *lut* is not None, the
        colormap will be resampled to have *lut* entries in the lookup table.
