colour.plotting.plot_RGB_chromaticities_in_chromaticity_diagram_CIE1931

colour.plotting.plot_RGB_chromaticities_in_chromaticity_diagram_CIE1931(RGB, colourspace='sRGB', chromaticity_diagram_callable_CIE1931=<function plot_RGB_colourspaces_in_chromaticity_diagram_CIE1931>, scatter_kwargs=None, **kwargs)[source]

Plots given RGB colourspace array in the CIE 1931 Chromaticity Diagram.

Parameters
  • RGB (array_like) – RGB colourspace array.

  • colourspace (unicode or RGB_Colourspace, optional) – RGB colourspace of the RGB array. colourspace can be of any type or form supported by the colour.plotting.filter_RGB_colourspaces() definition.

  • chromaticity_diagram_callable_CIE1931 (callable, optional) – Callable responsible for drawing the CIE 1931 Chromaticity Diagram.

  • scatter_kwargs (dict, optional) –

    Keyword arguments for the plt.scatter() definition. The following special keyword arguments can also be used:

    • c : unicode or array_like, if c is set to RGB, the scatter will use the colours as given by the RGB argument.

Other Parameters

**kwargs (dict, optional) – {colour.plotting.artist(), colour.plotting.diagrams.plot_chromaticity_diagram(), colour.plotting.diagrams.plot_RGB_colourspaces_in_chromaticity_diagram(), colour.plotting.render()}, Please refer to the documentation of the previously listed definitions. Also handles keywords arguments for deprecation management.

Returns

Current figure and axes.

Return type

tuple
