It must contain the following input variables:

x: str
order: int
data: Union[str, DataFrame, List[Dict]]

And accepts the following input variables as optional:

y: Optional[List[str]]
x_axis_name: Optional[str]
y_axis_name: Optional[str]
title: Optional[str]
rows_size: Optional[int]
cols_size: Optional[int]
padding: Optional[List[int]]
show_values: Optional[List[str]]
option_modifications: Optional[Dict]

Examples

An example of how the function expects the data to be represented is the following:

Segment, Price, Client category, Age, Geo, Acquisitive power, Family size, Policie tenure, Labour contract
Hogar, 21, 5, 12, 17, 3, 14, 3, 6
Móvil, 23, 16, 16, 14, 4, 2, 19, 12
Dental, 26, 21, 14, 17, 1, 2, 6, 3
Viajes, 24, 22, 15, 17, 8, 5, 15, 4
Accidentes, 22, 12, 18, 17, 5, 6, 1, 5
Seguro de vida, 22, 21, 19, 12, 7, 3, 2, 9
Jurídico, 25, 21, 13, 12, 10, 6, 13, 6
Dental Plus, 24, 4, 17, 17, 7, 9, 2, 3
Jubilación, 20, 4, 19, 17, 2, 2, 10, 8
Salud, 27, 24, 17, 17, 12, 1, 4, 1

Assuming that the previously shown data is stored in the file 'file.csv'.

The function has the option to hide or show each level by using the parameter show_values where the columns of the dataset that will show it's values have to be specified, by default it will not show any values.

When executing the following code:

s.plt.stacked_bar(
    data=pd.read_csv('file.csv'), x="Segment",
    x_axis_name='Distribution and weight of the Drivers',
    order=0, show_values=['Price'],
)

Variants

By setting the parameter variant to the following values the appearance of the chart can be changed:

Interesting Usages

• Showing proportions: Stacked bar charts are ideal for showing how a category is divided into subcategories. For example, you could use a stacked bar chart to show how a company's revenue by month is divided into different product categories.

  

• Comparing data: Stacked bar charts can also be used to compare data between different categories. For example, you could use a stacked bar chart to compare the revenue generated by different countries.
