Basic pie chart#
Demo of a basic pie chart plus a few additional features.
In addition to the basic pie chart, this demo shows a few optional features:
auto-labeling the percentage
offsetting a slice with "explode"
custom start angle
Note about the custom start angle:
startangle is 0, which would start the "Frogs" slice on the
positive x-axis. This example sets
startangle = 90 such that everything is
rotated counter-clockwise by 90 degrees, and the frog slice starts on the
import matplotlib.pyplot as plt # Pie chart, where the slices will be ordered and plotted counter-clockwise: labels = 'Frogs', 'Hogs', 'Dogs', 'Logs' sizes = [15, 30, 45, 10] explode = (0, 0.1, 0, 0) # only "explode" the 2nd slice (i.e. 'Hogs') fig1, ax1 = plt.subplots() ax1.pie(sizes, explode=explode, labels=labels, autopct='%1.1f%%', shadow=True, startangle=90) ax1.axis('equal') # Equal aspect ratio ensures that pie is drawn as a circle. plt.show()
The use of the following functions, methods, classes and modules is shown in this example:
