The universal registry instance is `matplotlib.colormaps`. There should be no need for users to instantiate `.ColormapRegistry` themselves. Read access uses a dict-like interface mapping names to `.Colormap`\s:: import matplotlib as mpl cmap = mpl.colormaps['viridis'] Returned `.Colormap`\s are copies, so that their modification does not change the global definition of the colormap. Additional colormaps can be added via `.ColormapRegistry.register`:: mpl.colormaps.register(my_colormap) To get a list of all registered colormaps, you can do:: from matplotlib import colormaps list(colormaps) cCs||_t||_dSN)_cmapstuple_builtin_cmaps)selfrrrr__init__ZszColormapRegistry.__init__cCs0z|j|WStyt|ddw)Nz is not a known colormap name)rrKeyError)r!itemrrr __getitem__^s  zColormapRegistry.__getitem__cC t|jSr)iterrr!rrr__iter__d zColormapRegistry.__iter__cCr&r)lenrr(rrr__len__gr*zColormapRegistry.__len__cCsdddd|DS)Nz'ColormapRegistry; available colormaps: z, css|] }d|dVqdS)'Nr).0rrrr lsz+ColormapRegistry.__str__..)joinr(rrr__str__jszColormapRegistry.__str__cCst|S)z Return a list of the registered colormap names.

The colormap name can then be used as a string argument to any ``cmap`` parameter in Matplotlib. It is also available in ``pyplot.get_cmap``. The colormap registry stores a copy of the given colormap, so that future changes to the original colormap instance do not affect the registered colormap. Think of this as the registry taking a snapshot of the colormap at registration. Parameters ---------- cmap : matplotlib.colors.Colormap The colormap to register. name : str, optional The name for the colormap. If not given, ``cmap.name`` is used. force : bool, default: False If False, a ValueError is raised if trying to overwrite an already registered name. True supports overwriting registered colormaps other than the builtin colormaps. rzA colormap named "z" is already registered.z Re-registering the builtin cmap z is not allowed.zOverwriting the cmap z" that was already in the registry.N) rZcheck_isinstancerColormapr ValueErrorr Z warn_externalrr)r!rrr3rrrregisterxs     zColormapRegistry.registercCs,||jvr td|d|j|ddS)a Remove a colormap from the registry. You cannot remove built-in colormaps. If the named colormap is not registered, returns with no error, raises if you try to de-register a default colormap. .. warning:: Colormap names are currently a shared namespace that may be used by multiple packages. Use `unregister` only if you know you have registered that name before. In particular, do not unregister just in case to clean the name before registering a new colormap.
