How to plot a half-black and half-white circle using Matplotlib?

To plot a half-black and half-white circle using Matplotlib, we can take the following steps −

• Set the figure size and adjust the padding between and around the subplots.
• Create a figure and a set of subplots.
• Initialize theta1 and theta2 to draw edges from theta1 to theta2 and vice-versa.
• Add the wedge instance on the current axes.
• Set equal scaling by changing axis limits.
• Set x and y scale.
• To display the figure, use show() method.

Example

import matplotlib.pyplot as plt from matplotlib.patches import Wedge plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True fig, ax = plt.subplots() theta1, theta2 = 0, 0 + 180 radius = 2 center = (0, 0) w1 = Wedge(center, radius, theta1, theta2, fc='black', edgecolor='black') w2 = Wedge(center, radius, theta2, theta1, fc='white', edgecolor='black') for wedge in [w1, w2]:    ax.add_artist(wedge) ax.axis('equal') ax.set_xlim(-5, 5) ax.set_ylim(-5, 5) plt.show()
