Matplotlib: Parametric curve

• 1. 模块：matplotlib.pyplot
• 2. 方法：scatter()

1. 基础绘图

import matplotlib.pyplot as plt


ax = plt.figure().add_subplot(projection='3d')

# Prepare arrays x, y, z
theta = np.linspace(-4 * np.pi, 4 * np.pi, 100)
z = np.linspace(-2, 2, 100)
r = z**2 + 1
x = r * np.sin(theta)
y = r * np.cos(theta)

ax.plot(x, y, z, label='parametric curve')
ax.legend()

plt.show()
