-Plot Hypervolume History with Reference Point
-===
+## Class or Function Names
+- plot_hypervolume_history
 
-This package provides a function to plot hypervolume history with the reference point information.
-
-# plot_hypervolume_history
+## Example
 ```python
-def plot_hypervolume_history(study, reference_point) -> "go.Figure"
-```
-
-Plot hypervolume history of all trials in a study.
-
-
-## Parameters
-- `study (Study)` – A Study object whose trials are plotted for their hypervolumes. The number of objectives must be 2 or more.
-- `reference_point (Sequence[float])` – A reference point to use for hypervolume computation. The dimension of the reference point must be the same as the number of objectives.
-
-
-## Returns
-- A `plotly.graph_objects.Figure` object.
-
-
-## Return type
-- `Figure`
-
-
-# Example
-
-The following code snippet shows how to plot optimization history.
-
-
-```python
-import optuna
-import optunahub
-
-
-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
