colour.plotting.diagrams.plot_chromaticity_diagram

colour.plotting.diagrams.plot_chromaticity_diagram(cmfs='CIE 1931 2 Degree Standard Observer', show_diagram_colours=True, show_spectral_locus=True, method='CIE 1931', **kwargs)

Plots the Chromaticity Diagram according to given method.

Parameters

• cmfs (unicode or XYZ_ColourMatchingFunctions, optional) – Standard observer colour matching functions used for computing the spectral locus boundaries. cmfs can be of any type or form supported by the colour.plotting.filter_cmfs() definition.

• show_diagram_colours (bool, optional) – Whether to display the Chromaticity Diagram background colours.

• show_spectral_locus (bool, optional) – Whether to display the Spectral Locus.

• method (unicode, optional) – {‘CIE 1931’, ‘CIE 1960 UCS’, ‘CIE 1976 UCS’}, Chromaticity Diagram method.

• **kwargs (dict, optional) – {colour.plotting.artist(), colour.plotting.diagrams.plot_spectral_locus(), colour.plotting.diagrams.plot_chromaticity_diagram_colours(), colour.plotting.render()}, Please refer to the documentation of the previously listed definitions.

Returns

Current figure and axes.

Return type
