Group values from a Pandas Series according to given intervals and represent them graphically with Plotly

plotly_intervals

A function that groups values from a Pandas Series according to given intervals and represent them graphically in the form of bar chart or pie chart with Plotly. Serval parameters can be adjusted :

• The plot title
• x/y axis labels
• The intervals chosen for the grouping of values (example: [[0,5], [5,10], ...]
• If no interval is defined, default intervals will be generated from the values present in the Pandas Series
• Display a last interval grouping all the values greater than the last given interval
• The plot kind (bar chart or pie chart)
• Grid display
• Choice of bar color for bar chart
• The output (static/non-interactive image, interactive figure, plotly Figure object, bytes, intervals dictionnary)

Exemples

For this example we will use a dataset on exoplanets and recover in the form of Pandas Series the column relating to the distance of planetary systems from us :

dist = df['sy_dist']

To start we will simply insert the Series into the function without adding any parameters :

plot_group(dist)

Intervals have been defined automatically by the function based on the values present in the Series and their dispersion (see the comments in the function for more information).

Now let's relaunch the function but adding some parameters and, in particular, custom intervals.

# Custom intervals
inter = [[0,25], [25,50], [75,100], [100,125], [125,150]]

plot_group(dist,
intervals = inter, 
title='Distance of exoplanets from us', 
x_label='Distance [parsec]',
y_label='Number of exoplanets',
bar_color='#b4522b')

The higher_vals parameter allows to add a last interval grouping all the values of the Series greater than the last interval provided

# Custom intervals
inter = [[0,400], [400,800], [800,1200]]

plot_group(dist,
intervals = inter,
higher_vals=True,
title='Distance of exoplanets from us', 
x_label='Distance [parsec]',
y_label='Number of exoplanets',
bar_color='#b4522b')

The representation can also be done in the form of a pie chart :

inter = [[0,400], [400,800], [800,1200]]

plot_group(dist,
kind='pie_hole',
intervals = inter,
higher_vals=True, 
title='Distance of exoplanets from us')
