Plot MacAdam (1942) Ellipses (Observer PGN) in the Chromaticity Diagram according to given method.

  • chromaticity_diagram_callable (Callable) – Callable responsible for drawing the Chromaticity Diagram.

  • method (Union[Literal['CIE 1931', 'CIE 1960 UCS', 'CIE 1976 UCS'], str]) – Chromaticity Diagram method.

  • chromaticity_diagram_clipping (bool) – Whether to clip the Chromaticity Diagram colours with the ellipses.

  • ellipse_kwargs (Optional[Union[Dict, List[Dict]]]) – Parameters for the Ellipse class, ellipse_kwargs can be either a single dictionary applied to all the ellipses with same settings or a sequence of dictionaries with different settings for each ellipse.

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