colour.plotting.diagrams.plot_chromaticity_diagram¶

colour.plotting.diagrams.plot_chromaticity_diagram(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, method: Union[Literal['CIE 1931', 'CIE 1960 UCS', 'CIE 1976 UCS'], str] = 'CIE 1931', **kwargs: Any) → Tuple[matplotlib.figure.Figure, matplotlib.axes._axes.Axes][source]¶

Plot the Chromaticity Diagram according to given method.

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.
method (Union[Literal['CIE 1931', 'CIE 1960 UCS', 'CIE 1976 UCS'], str]) – Chromaticity Diagram method.
kwargs (Any) – {colour.plotting.artist(), colour.plotting.diagrams.plot_spectral_locus(), colour.plotting.diagrams.plot_chromaticity_diagram_colours(), colour.plotting.render()}, See the documentation of the previously listed definitions.

Returns

Current figure and axes.

Return type

tuple
