why use pandas-plots
pandas-plots
is a package to help you examine and visualize data that are organized in a pandas DataFrame. It provides a high level api to pandas / plotly with some selected functions and predefined options:
-
tbl
utilities for table descriptions- 🌟
show_num_df()
displays a table as styled version with additional information describe_df()
an alternative version of pandasdescribe()
functionpivot_df()
gets a pivot table of a 3 column dataframe-
⚠️
pivot_df()
is depricated and wont get further updates. Its features are well covered in standardpd.pivot_table()
-
- 🌟
-
pls
for plotly visualizationsplot_box()
auto annotated boxplot w/ violin optionplot_boxes()
multiple boxplots (annotation is experimental)plot_stacked_bars()
shortcut to stacked bars 😄plots_bars()
a standardized bar plot for a categorical column- features convidence intervals via
use_ci
option
- features convidence intervals via
- 🆕
plot_histogram()
histogram for one or more numerical columns - 🆕
plot_joints()
a joint plot for exactly two numerical columns plot_quadrants()
quickly shows a 2x2 heatmap
-
ven
offers functions for venn diagramsshow_venn2()
displays a venn diagram for 2 setsshow_venn3()
displays a venn diagram for 3 sets
-
hlp
contains some (variety) helper functionsdf_to_series()
converts a dataframe to a seriesmean_confidence_interval()
calculates mean and confidence interval for a serieswrap_text()
formats strings or lists to a given width to fit nicely on the screenreplace_delimiter_outside_quotes()
when manual import of csv files is needed: replaces delimiters only outside of quotes- 🆕
create_barcode_from_url()
creates a barcode from a given URL - 🆕
add_datetime_col()
adds a datetime columns to a dataframe
note: theme setting can be controlled through all functions by setting the environment variable
THEME
to either light or dark

pls.plot_box(df['fare'], height=400, violin=True)
# quick and exhaustive description of any table
tbl.describe_df(df, 'taxis', top_n_uniques=5)
# show bars with confidence intervals
_df = df[["payment", "fare"]]
pls.plot_bars(
_df,
dropna=False,
use_ci=True,
height=600,
width=800,
precision=1,
)
# show venn diagram for 3 sets
from pandas_plots import ven
set_a = {'ford','ferrari','mercedes', 'bmw'}
set_b = {'opel','bmw','bentley','audi'}
set_c = {'ferrari','bmw','chrysler','renault','peugeot','fiat'}
_df, _details = ven.show_venn3(
title="taxis",
