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()Output
