sum_over
must be a string or False. fig : matplotlib.figure.Figure, optional
Defaults to a new figure.
 kwargs
Other arguments for
UpSet
Returns:  subplots : dict of matplotlib.axes.Axes

class
upsetplot.
UpSet
(data, orientation='horizontal', sort_by='degree', sort_categories_by='cardinality', subset_size='auto', sum_over=None, min_subset_size=None, max_subset_size=None, min_degree=None, max_degree=None, facecolor='auto', other_dots_color=0.18, shading_color=0.05, with_lines=True, element_size=32, intersection_plot_elements=6, totals_plot_elements=2, show_counts='', show_percentages=False)[source]¶ Manage the data and drawing for a basic UpSet plot
Primary public method is
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’, None}
If ‘cardinality’, subset are listed from largest to smallest. If ‘degree’, they are listed in order of the number of categories intersected. If None, the order they appear in the data input is used.
 sort_categories_by : {‘cardinality’, None}
Whether to sort the categories by total cardinality, or leave them in the provided order.
 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, unlesssum_over
is specified. Ifdata
is a Series with at most one row for each group, use the value of the Series. Ifdata
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 bysum_over
.
 sum_over : str or None
If
subset_size='sum'
or'auto'
, then the intersection size is the sum of the specified field in thedata
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
. 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.
 min_degree : int, optional
Minimum degree of a subset to be shown in the plot.
 max_degree : int, optional
Maximum degree of a subset to be shown in the plot.
 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.
 other_dots_color : matplotlib color or float
Color for shading of inactive dots, or opacity (between 0 and 1) applied to facecolor.
 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.
 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.
 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.
 show_percentages : bool, default=False
Whether to label the intersection size bars with the percentage of the intersection relative to the total dataset. This may be applied with or without show_counts.

seaborn.catplot()
.Our implementation automatically determines ‘ax’, ‘data’, ‘x’, ‘y’ and ‘orient’, so these are prohibited keys in
kw
.

add_stacked_bars
(self, by, sum_over=None, colors=None, elements=3, title=None)[source]¶ Add a stacked bar chart over subsets when
plot()
is called.Used to plot categorical variable distributions within each subset.
Parameters:  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.

Dataset loading and generation¶

upsetplot.
from_contents
(contents, data=None, id_column='id')[source]¶ Build data from category listings
Parameters:  contents : Mapping (or iterable over pairs) of strings to sets
Keys are category names, values are sets of identifiers (int or string).
 data : DataFrame, optional
If provided, this should be indexed by the identifiers used in
Python Documentation contents
. id_column : str, default=’id’
The column name to use for the identifiers in the output.
Returns:  DataFrame
data
is returned with its index indicating category membership, including a column named according to id_column. If data is not given, the order of rows is not assured.
Notes
The order of categories in the output DataFrame is determined from
Python Documentation contents
, which may have nondeterministic iteration order.Examples
>>> from upsetplot import from_contents >>> contents = {'cat1': ['a', 'b', 'c'], ... 'cat2': ['b', 'd'], ... 'cat3': ['e']} >>> from_contents(contents) id cat1 cat2 cat3 True False False a True False b False False c False True False d False True e >>> import pandas as pd >>> contents = {'cat1': [0, 1, 2], ... 'cat2': [1, 3], ... 'cat3': [4]} >>> data = pd.DataFrame({'favourite': ['green', 'red', 'red', ... 'yellow', 'blue']}) >>> from_contents(contents, data=data) id favourite cat1 cat2 cat3 True False False 0 green True False 1 red False False 2 red False True False 3 yellow False True 4 blue

upsetplot.
from_indicators
(indicators, data=None)[source]¶ Load category membership indicated by a boolean indicator matrix
This loader also supports the case where the indicator columns can be derived from
data
.Parameters:  indicators : DataFramelike of booleans, Sequence of str, or callable
Specifies the category indicators (boolean mask arrays) within
data
, i.e. which records indata
belong to which categories.If a list of strings, these should be column names found in
data
whose values are boolean mask arrays.If a DataFrame, its columns should correspond to categories, and its index should be a subset of those in
data
, values should be True where a data record is in that category, and False or NA otherwise.If callable, it will be applied to
data
after the latter is converted to a Series or DataFrame. data : Serieslike or DataFramelike, optional
If given, the index of category membership is attached to this data. It must have the same length as
indicators
. If not given, the series will contain the value 1.
Returns:  DataFrame or Series
data
is returned with its index indicating category membership. It will be a Series ifdata
is a Series or 1d numeric array or None.
Notes
Categories with indicators that are all False will be removed.
Examples
>>> import pandas as pd >>> from upsetplot import from_indicators
Just indicators >>> indicators = {“cat1”: [True, False, True, False], … “cat2”: [False, True, False, False], … “cat3”: [True, True, False, False]} >>> from_indicators(indicators) cat1 cat2 cat3 True False True 1.0 False True True 1.0 True False False 1.0 False False False 1.0 Name: ones, dtype: float64
Where indicators are included within data, specifying columns by name >>> data = pd.DataFrame({“value”: [5, 4, 6, 4], **indicators}) >>> from_indicators([“cat1”, “cat3”], data=data)
value cat1 cat2 cat3cat1 cat3 True True 5 True False True False True 4 False True True True False 6 True False False False False 4 False False False
Making indicators out of all boolean columns >>> from_indicators(lambda data: data.select_dtypes(bool), data=data)
value cat1 cat2 cat3cat1 cat2 cat3 True False True 5 True False True False True True 4 False True True True False False 6 True False False False False False 4 False False False
Using a dataset with missing data, we can use missingness as an indicator >>> data = pd.DataFrame({“val1”: [pd.NA, .7, pd.NA, .9], … “val2”: [“male”, pd.NA, “female”, “female”], … “val3”: [pd.NA, pd.NA, 23000, 78000]}) >>> from_indicators(pd.isna, data=data)
val1 val2 val3val1 val2 val3 True False True <NA> male <NA> False True True 0.7 <NA> <NA> True False False <NA> female 23000 False False False 0.9 female 78000
