matplotlib.colors.ListedColormap
-
class matplotlib.colors.ListedColormap(colors, name='from_list', N=None)
-
Colormap object generated from a list of colors.
This may be most useful when indexing directly into a colormap, but it can also be used to generate special colormaps for ordinary mapping.
Make a colormap from a list of colors.
- colors
- a list of matplotlib color specifications, or an equivalent Nx3 or Nx4 floating point array (N rgb or rgba values)
- name
- a string to identify the colormap
- N
-
the number of entries in the map. The default is None, in which case there is one colormap entry for each element in the list of colors. If:
N < len(colors)
the list will be truncated at N. If:
N > len(colors)
the list will be extended by repetition.
-
reversed(name=None)
-
Make a reversed instance of the Colormap.
Parameters: name : str, optional
The name for the reversed colormap. If it’s None the name will be the name of the parent colormap + “_r”.
Returns: ListedColormap
A reversed instance of the colormap.
