colour.plotting.plot_multi_sds_colour_quality_scales_bars

colour.plotting.plot_multi_sds_colour_quality_scales_bars(sds: Sequence[SpectralDistribution | MultiSpectralDistributions] | SpectralDistribution | MultiSpectralDistributions | ValuesView, method: Literal['NIST CQS 7.4', 'NIST CQS 9.0'] | str = 'NIST CQS 9.0', **kwargs: Any) → Tuple[Figure, Axes]

Plot the Colour Quality Scale (CQS) of the specified illuminants or light sources spectral distributions.

Parameters:

• sds (Sequence[SpectralDistribution | MultiSpectralDistributions] | SpectralDistribution | MultiSpectralDistributions | ValuesView) – Spectral distributions or multi-spectral distributions to plot. sds can be a single colour.MultiSpectralDistributions class instance, a list of colour.MultiSpectralDistributions class instances or a list of colour.SpectralDistribution class instances.

• method (Literal['NIST CQS 7.4', 'NIST CQS 9.0'] | str) – Colour Quality Scale (CQS) computation method.

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

Returns:

Current figure and axes.

Return type:

tuple

Examples

>>> from colour import SDS_ILLUMINANTS, SDS_LIGHT_SOURCES
>>> illuminant = SDS_ILLUMINANTS["FL2"]
>>> light_source = SDS_LIGHT_SOURCES["Kinoton 75P"]
>>> plot_multi_sds_colour_quality_scales_bars([illuminant, light_source])
