Matplotlib pie chart The code below creates a pie chart:

import matplotlib.pyplot as plt

# Data to plot labels = 'Python', 'C++', 'Ruby', 'Java' sizes = [215, 130, 245, 210] colors = ['gold', 'yellowgreen', 'lightcoral', 'lightskyblue'] explode = (0.1, 0, 0, 0) # explode 1st slice

# Plot plt.pie(sizes, explode=explode, labels=labels, colors=colors, autopct='%1.1f%%', shadow=True, startangle=140)

plt.axis('equal') plt.show()

Output:

To add a legend use the plt.legend() function:

import matplotlib.pyplot as plt

labels = ['Cookies', 'Jellybean', 'Milkshake', 'Cheesecake'] sizes = [38.4, 40.6, 20.7, 10.3] colors = ['yellowgreen', 'gold', 'lightskyblue', 'lightcoral'] patches, texts = plt.pie(sizes, colors=colors, shadow=True, startangle=90) plt.legend(patches, labels, loc="best") plt.axis('equal') plt.tight_layout() plt.show()

Output:
