    bar_width: float = 0.3,
        Width of the bar of the barplot.
    height: float = None,
        Height of the barplot. By default golden ratio of the width.

        Whetever to show or not the barplot title.
    legend_position: str = "best",
        Legend position, by default "best".
    data_label: str = None,
        Barplot's data_label.
        Use None for not showing any data_label (default).
    title: str = None,
        Barplot's title.
        Use None for not showing any title (default).
    path: str = None,
        Path where to save the barplot.
        Use None for not saving it (default).
    colors: Dict[str, str] = None,
        Dict of colors to be used for innermost index of dataframe.
        By default None, using the default color tableau from matplotlib.
    alphas: Dict[str, float] = None,
        Dict of alphas to be used for innermost index of dataframe.
        By default None, using the default alpha.
    orientation: str = "vertical",
        Orientation of the bars.
        Can either be "vertical" of "horizontal".
    subplots: bool = False,
        Whetever to slit the top indexing layer to multiple subplots.
    plots_per_row: Union[int, str] = "auto",
        If subplots is True, specifies the number of plots for row.
        If "auto" is used, for vertical the default is 2 plots per row,
        while for horizontal the default is 4 plots per row.
    minor_rotation: float = 0,
        Rotation for the minor ticks of the bars.
    major_rotation: float = 0,
        Rotation for the major ticks of the bars.
    unique_minor_labels: bool = False,
        Avoid replicating minor labels on the same axis in multiple subplots settings.
    unique_major_labels: bool = True,
        Avoid replicating major labels on the same axis in multiple subplots settings.

        Avoid replication of data axis label when using subplots.
    auto_normalize_metrics: bool = True,
        Whetever to apply or not automatic normalization
        to the metrics that are recognized to be between
        zero and one. For example AUROC, AUPRC or accuracy.
    placeholder: bool = False,

        the word "placeholder". Useful when generating placeholder data.
    scale: str = "linear",
        Scale to use for the barplots.
        Can either be "linear" or "log".
    custom_defaults: Dict[str, List[str]],
        Dictionary to normalize labels.
    letter: str = None,
        Letter to show on the top left of the figure.
        This is sometimes necessary on papers.
        By default it is None, that is no letter to be shown.

    Raises
    ------
