colour.plotting.plot_RGB_scatter

colour.plotting.plot_RGB_scatter(RGB, colourspace, reference_colourspace='CIE xyY', colourspaces=None, segments=8, show_grid=True, grid_segments=10, show_spectral_locus=False, spectral_locus_colour=None, points_size=12, cmfs='CIE 1931 2 Degree Standard Observer', chromatically_adapt=False, convert_kwargs=None, **kwargs)[source]

Plots given RGB colourspace array in a scatter plot.

Parameters
  • RGB (array_like) – RGB colourspace array.

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

  • reference_colourspace (unicode, optional) – Reference colourspace model to plot the gamuts into, see colour.COLOURSPACE_MODELS attribute for the list of supported colourspace models.

  • colourspaces (unicode or RGB_Colourspace or array_like) – RGB colourspaces to plot the gamuts. colourspaces elements can be of any type or form supported by the colour.plotting.filter_RGB_colourspaces() definition.

  • segments (int, optional) – Edge segments count for each RGB colourspace cubes.

  • show_grid (bool, optional) – Whether to show a grid at the bottom of the RGB colourspace cubes.

  • grid_segments (bool, optional) – Edge segments count for the grid.

  • show_spectral_locus (bool, optional) – Whether to show the spectral locus.

  • spectral_locus_colour (array_like, optional) – Spectral locus colour.

  • points_size (numeric, optional) – Scatter points size.

  • cmfs (unicode or XYZ_ColourMatchingFunctions, optional) – 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.

  • chromatically_adapt (bool, optional) – Whether to chromatically adapt the RGB colourspaces given in colourspaces to the whitepoint of the default plotting colourspace.

  • convert_kwargs (dict, optional) – Keyword arguments for the colour.convert() definition.

Other Parameters

**kwargs (dict, optional) – {colour.plotting.artist(), colour.plotting.plot_RGB_colourspaces_gamuts()}, Please refer to the documentation of the previously listed definitions.

Returns

Current figure and axes.
