To have actual or any custom values in Matplotlib pie chart displayed, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Make lists of labels, fractions, explode position and get the sum of fractions to calculate the percentage
- Make a pie chart using labels, fracs and explode with autopct=lambda p: <calculation for percentage>.
- To display the figure, use show() method.
Example
import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True labels = ('Read', 'Eat', 'Sleep', 'Repeat') fracs = [5, 3, 4, 1] total = sum(fracs) explode = (0, 0.05, 0, 0) plt.pie(fracs, explode=explode, labels=labels, autopct=lambda p: '{:.0f}%'.format(p * total / 100), shadow=True, startangle=90) plt.show()
