- optuna.visualization.plot_hypervolume_history(study, reference_point)[source]
Plot hypervolume history of all trials in a study.

The following code snippet shows how to plot optimization history.
import optuna def objective(trial): x = trial.suggest_float("x", 0, 5) y = trial.suggest_float("y", 0, 3) v0 = 4 * x ** 2 + 4 * y ** 2 v1 = (x - 5) ** 2 + (y - 5) ** 2 return v0, v1 study = optuna.create_study(directions=["minimize", "minimize"]) study.optimize(objective, n_trials=50) reference_point=[100., 50.] fig = optuna.visualization.plot_hypervolume_history(study, reference_point) fig.show()
