In Matplotlib, show the percentage or proportional data where each slice of pie represents a category
In this article, we can create a pie chart to show our daily activities, i.e., sleeping, eating, working, and playing. Using plt.pie() method, we can create a pie chart with the given different data sets for different activities.
Steps
Create a list of days, i.e., [1, 2, 3, 4, 5]. Similarly, make lists for sleeping, eating, playing, and working. There is an activities list that keeps “sleeping”, “eating”, “working” and “playing”.
Make a list of colors.
Use plt.pie() method to draw the pie chart, where slices, activities, colors as cols, etc. are passed.
Set a title for the axes, i.e., “Pie Chart”.
To show the figure use plt.show() method.
Example
import matplotlib.pyplot as plt
days = [1, 2, 3, 4, 5]
sleeping = [7, 8, 6, 11, 7]
eating = [2, 3, 4, 3, 2]
working = [7, 8, 7, 2, 2]
playing = [8, 5, 7, 8, 13]
slices = [7, 2, 3, 13]
activities = ['sleeping', 'eating', 'working', 'playing']
cols = ['c', 'm', 'r', 'b']
plt.pie(slices,
labels=activities,
colors=cols,
startangle=90,
shadow=True,
explode=(0, 0.1, 0, 0),
autopct='%1.1f%%')
plt.title('Pie Plot')
plt.show()Output
When we execute the code, it will produce the following output −
