Pie Plot or a Pie Chart

A pie plot or a pie chart is a circular statistical graphic technique, in which a circle is divided into slices with respect to numerical proportion. In a pie chart, the arc length, central angle, and area of each slice, is proportional to the quantity it represents. The sum of the total is always equal to 100 percent in the basic pie chart.

matplotlib.pyplot.pie() Method

The name pie in the pie plot is derived for its resemblance to a pie that has been sliced. Pie charts are very widely used in the different types of projects and business world. Matplotlib has a defined function in matplotlib.pyplot.pie() for plotting a pie chart.

Syntax

matplotlib.pyplot.pie(sizes, labels=labels, autopct='%1.1f%%')
#Square textbox style

Example

Python program for pie chart

# Data Visualization using Python
# Pie Chart

import matplotlib.pyplot as plt

# Pie chart, where the slices will be ordered 
# and plotted counter-clockwise:
labels = 'A', 'B', 'C', 'D', 'E', 'F'
sizes = [15, 20, 10, 17, 1, 37]


plt.figure()
plt.pie(sizes, labels=labels, autopct='%1.1f%%')
# Equal aspect ratio ensures that pie is drawn 
# as a circle.
plt.axis('equal')  

plt.show()

Output:

Output is as figure
