To plot a rectangle inside a circle in matplotlib, we can take the following steps −
Create a new figure or activate an existing figure using figure method.
Add a subplot to the current axis.
Make a rectangle and a circle instance using Rectangle() and Circle() class.
Add a patch on the axes.
Scale x and y axes using xlim() and ylim() methods.
To display the figure, use show() method.
Example
import matplotlib from matplotlib import pyplot as plt, patches plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True fig = plt.figure() ax = fig.add_subplot(111) rect1 = patches.Rectangle((-2, -2), 4, 2, color='yellow') circle1 = matplotlib.patches.Circle((0, 0), radius=3, color='red') ax.add_patch(circle1) ax.add_patch(rect1) plt.xlim([-5, 5]) plt.ylim([-5, 5]) plt.axis('equal') plt.show()
