colour.plotting.temperature.plot_planckian_locus#

colour.plotting.temperature.plot_planckian_locus(planckian_locus_colours: Optional[Union[ArrayLike, str]] = None, planckian_locus_opacity: Floating = 1, planckian_locus_labels: Optional[Sequence] = None, method: Union[Literal['CIE 1931', 'CIE 1960 UCS', 'CIE 1976 UCS'], str] = 'CIE 1931', **kwargs: Any) → Tuple[plt.Figure, plt.Axes][source]#

Plot the Planckian Locus according to given method.

Parameters

  • planckian_locus_colours (Optional[Union[ArrayLike, str]]) – Colours of the Planckian Locus, if planckian_locus_colours is set to RGB, the colours will be computed according to the corresponding chromaticity coordinates.

  • planckian_locus_opacity (Floating) – Opacity of the Planckian Locus.

  • planckian_locus_labels (Optional[Sequence]) – Array of labels used to customise which iso-temperature lines will be drawn along the Planckian Locus. Passing an empty array will result in no iso-temperature lines being drawn.

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

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

Returns

Current figure and axes.

Return type

tuple
