Python使用matplotlib绘制三维参数曲线操作示例

import matplotlib as mpl
from mpl_toolkits.mplot3d importAxes3D
import numpy as np
import matplotlib.pyplot as plt
mpl.rcParams['legend.fontsize']=10#图例字号
fig = plt.figure()
ax = fig.gca(projection='3d')#三维图形
theta = np.linspace(-4* np.pi,4* np.pi,100)
z = np.linspace(-4,4,100)*0.3#测试数据
r = z**3+1
x = r * np.sin(theta)
y = r * np.cos(theta)
ax.plot(x, y, z, label='parametric curve')
ax.legend()
plt.show()
