colour.plotting.plot_multi_functions

colour.plotting.plot_multi_functions(functions, samples=None, log_x=None, log_y=None, plot_kwargs=None, **kwargs)[source]

Plots given functions.

Parameters
  • functions (dict) – Functions to plot.

  • samples (array_like, optional,) – Samples to evaluate the functions with.

  • log_x (int, optional) – Log base to use for the x axis scale, if None, the x axis scale will be linear.

  • log_y (int, optional) – Log base to use for the y axis scale, if None, the y axis scale will be linear.

  • plot_kwargs (dict or array_like, optional) – Keyword arguments for the plt.plot() definition, used to control the style of the plotted functions. plot_kwargs can be either a single dictionary applied to all the plotted functions with same settings or a sequence of dictionaries with different settings for each plotted function.

Other Parameters

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

Returns

Current figure and axes.

Return type

tuple

...     'Gamma 2.6' : lambda x: x ** (1 / 2.6),
... }
