colour.plotting.spds_chromaticity_diagram_plot_CIE1931¶

colour.plotting.spds_chromaticity_diagram_plot_CIE1931(spds, cmfs='CIE 1931 2 Degree Standard Observer', annotate=True, chromaticity_diagram_callable_CIE1931=<function chromaticity_diagram_plot_CIE1931>, **kwargs)[source]¶

Plots given spectral power distribution chromaticity coordinates into the CIE 1931 Chromaticity Diagram.

Other Parameters:
Parameters:	spds (array_like, optional) – Spectral power distributions to plot. cmfs (unicode, optional) – Standard observer colour matching functions used for diagram bounds. annotate (bool) – Should resulting chromaticity coordinates annotated with their respective spectral power distribution names. chromaticity_diagram_callable_CIE1931 (callable, optional) – Callable responsible for drawing the CIE 1931 Chromaticity Diagram.
	*kwargs (dict, optional) – {`colour.plotting.render()`}, Please refer to the documentation of the previously listed definition. show_diagram_colours* (bool, optional) – {`colour.plotting.chromaticity_diagram_plot_CIE1931()`}, Whether to display the chromaticity diagram background colours. use_cached_diagram_colours (bool, optional) – {`colour.plotting.chromaticity_diagram_plot_CIE1931()`}, Whether to used the cached chromaticity diagram background colours image.
Returns:	Current figure or None.
Return type:	Figure
