colour.plotting.plot_chromaticity_diagram_CIE1931

colour.plotting.plot_chromaticity_diagram_CIE1931(cmfs: Union[colour.colorimetry.spectrum.MultiSpectralDistributions, str, Sequence[Union[colour.colorimetry.spectrum.MultiSpectralDistributions, str]]] = 'CIE 1931 2 Degree Standard Observer', show_diagram_colours: bool = True, show_spectral_locus: bool = True, **kwargs: Any) → Tuple[matplotlib.figure.Figure, matplotlib.axes._axes.Axes]

Plot the CIE 1931 Chromaticity Diagram.

Parameters

• cmfs (Union[colour.colorimetry.spectrum.MultiSpectralDistributions, str, Sequence[Union[colour.colorimetry.spectrum.MultiSpectralDistributions, str]]]) – 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) – Whether to display the Chromaticity Diagram background colours.

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

• kwargs (Any) – {colour.plotting.artist(), colour.plotting.diagrams.plot_chromaticity_diagram(), colour.plotting.render()}, See the documentation of the previously listed definitions.

Returns

Current figure and axes.

Return type

tuple
