matplotlib.pyplot.register_cmap

matplotlib.pyplot.register_cmap(name=None, cmap=None, data=None, lut=None)

Add a colormap to the set recognized by get_cmap().

It can be used in two ways:

register_cmap(name='swirly', cmap=swirly_cmap)

register_cmap(name='choppy', data=choppydata, lut=128)

In the first case, cmap must be a matplotlib.colors.Colormap instance. The name is optional; if absent, the name will be the name attribute of the cmap.

In the second case, the three arguments are passed to the LinearSegmentedColormap initializer, and the resulting colormap is registered.
