Plotting a 2D Pareto front.

class ParetoPlotBiObjective(ax, obj_values, pareto_optimal_loc, obj_names, all_pareto_optimal, is_non_feasible, bi_obj=False, show_non_feasible=True)[source]#

Bases: object

Plot a 2D Pareto front on a Matplotlib axes.

Parameters:

  • ax (Axes) -- The Axes on which to plot.

  • obj_values (ndarray) -- The objective function array, of size (n_samples, n_objs).

  • pareto_optimal_loc (BooleanArray) -- A vector of booleans of size n_samples, True if the point is Pareto optimal.

  • obj_names (Sequence[str]) -- The names of the objectives.

  • all_pareto_optimal (BooleanArray) -- The indices of points that are Pareto optimal w.r.t. all criteria.

  • is_non_feasible (BooleanArray) -- An Array of booleans of size n_samples, True if non_feasible.

  • bi_obj (bool) --

    True if there are only two objective values.

    By default it is set to False.

  • show_non_feasible (bool) --

    True to show the non-feasible points.

    By default it is set to True.

plot_on_axes()[source]#

Plot the Pareto points on the Matplolib axes.

Return type:

None
