argopy.ArgoColors

class ArgoColors(name: str = 'Set1', N: int | None = None)

Class to manage discrete coloring for Argo related variables

Call signatures:

from argopy.plot import ArgoColors

ArgoColors().list_valid_known_colormaps
ArgoColors().known_colormaps.keys()

ArgoColors('data_mode')
ArgoColors('data_mode').cmap
ArgoColors('data_mode').definition

ArgoColors('Set2').cmap
ArgoColors('Spectral', N=25).cmap

__init__(name: str = 'Set1', N: int | None = None)

Parameters:

• name (str, default: 'Set1') – Name of the colormap to use.

• N (int, default: None) – Number of colors to reduce the colormap to. If set to None, use the known quantitative colormap number of colors or fall back on a default 12 value.
