class UpSet:
    """Manage the data and drawing for a basic UpSet plot

    Primary public method is :meth:`plot`.

    Parameters
    ----------
    data : pandas.Series or pandas.DataFrame
        Elements associated with categories (a DataFrame), or the size of each
        subset of categories (a Series).
        Should have MultiIndex where each level is binary,
        corresponding to category membership.
        If a DataFrame, `sum_over` must be a string or False.
    orientation : {'horizontal' (default), 'vertical'}
        If horizontal, intersections are listed from left to right.
    sort_by : {'cardinality', 'degree', '-cardinality', '-degree',
               'input', '-input'}
        If 'cardinality', subset are listed from largest to smallest.
        If 'degree', they are listed in order of the number of categories
        intersected. If 'input', the order they appear in the data input is
        used.
        Prefix with '-' to reverse the ordering.

        Note this affects ``subset_sizes`` but not ``data``.
    sort_categories_by : {'cardinality', '-cardinality', 'input', '-input'}
        Whether to sort the categories by total cardinality, or leave them
        in the input data's provided order (order of index levels).
        Prefix with '-' to reverse the ordering.
    subset_size : {'auto', 'count', 'sum'}
        Configures how to calculate the size of a subset. Choices are:

        'auto' (default)
            If `data` is a DataFrame, count the number of rows in each group,
            unless `sum_over` is specified.
            If `data` is a Series with at most one row for each group, use
            the value of the Series. If `data` is a Series with more than one
            row per group, raise a ValueError.
        'count'
            Count the number of rows in each group.
        'sum'
            Sum the value of the `data` Series, or the DataFrame field
            specified by `sum_over`.
    sum_over : str or None
        If `subset_size='sum'` or `'auto'`, then the intersection size is the
        sum of the specified field in the `data` DataFrame. If a Series, only
        None is supported and its value is summed.
    min_subset_size : int, optional
        Minimum size of a subset to be shown in the plot. All subsets with
        a size smaller than this threshold will be omitted from plotting.
        Size may be a sum of values, see `subset_size`.

        .. versionadded:: 0.5
    max_subset_size : int, optional
        Maximum size of a subset to be shown in the plot. All subsets with
        a size greater than this threshold will be omitted from plotting.

        .. versionadded:: 0.5
    min_degree : int, optional
        Minimum degree of a subset to be shown in the plot.

        .. versionadded:: 0.5
    max_degree : int, optional
        Maximum degree of a subset to be shown in the plot.

        .. versionadded:: 0.5
    facecolor : 'auto' or matplotlib color or float
        Color for bar charts and active dots. Defaults to black if
        axes.facecolor is a light color, otherwise white.

        .. versionchanged:: 0.6
            Before 0.6, the default was 'black'
    other_dots_color : matplotlib color or float
        Color for shading of inactive dots, or opacity (between 0 and 1)
        applied to facecolor.

        .. versionadded:: 0.6
    shading_color : matplotlib color or float
        Color for shading of odd rows in matrix and totals, or opacity (between
        0 and 1) applied to facecolor.

        .. versionadded:: 0.6
    with_lines : bool
        Whether to show lines joining dots in the matrix, to mark multiple
        categories being intersected.
    element_size : float or None
        Side length in pt. If None, size is estimated to fit figure
    intersection_plot_elements : int
        The intersections plot should be large enough to fit this many matrix
        elements. Set to 0 to disable intersection size bars.

        .. versionchanged:: 0.4
            Setting to 0 is handled.
    totals_plot_elements : int
        The totals plot should be large enough to fit this many matrix
        elements.
    show_counts : bool or str, default=False
        Whether to label the intersection size bars with the cardinality
        of the intersection. When a string, this formats the number.
        For example, '{:d}' is equivalent to True.
        Note that, for legacy reasons, if the string does not contain '{',
        it will be interpreted as a C-style format string, such as '%d'.
    show_percentages : bool or str, default=False
        Whether to label the intersection size bars with the percentage
        of the intersection relative to the total dataset.
        When a string, this formats the number representing a fraction of
        samples.
        For example, '{:.1%}' is the default, formatting .123 as 12.3%.
        This may be applied with or without show_counts.

        .. versionadded:: 0.4
    include_empty_subsets : bool (default=False)
        If True, all possible category combinations will be shown as subsets,
        even when some are not present in data.

        ----------
        by : str
            Column name within the dataframe for color coding the stacked bars,
            containing discrete or categorical values.
        sum_over : str, optional
            Ordinarily the bars will chart the size of each group. sum_over
            may specify a column which will be summed to determine the size
            of each bar.
        colors : Mapping, list-like, str or callable, optional
            The facecolors to use for bars corresponding to each discrete
            label, specified as one of:

            Mapping
                Maps from label to matplotlib-compatible color specification.
            list-like
                A list of matplotlib colors to apply to labels in order.
            str
                The name of a matplotlib colormap name.
            callable
                When called with the number of labels, this should return a
                list-like of that many colors.  Matplotlib colormaps satisfy
                this callable API.
            None
                Uses the matplotlib default colormap.
        elements : int, default=3
            Size of the axes counted in number of matrix elements.
        title : str, optional
            The axis title labelling bar length.
