python中的3d曲线箭头

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# 生成曲线箭头的数据
t = np.linspace(0, 10, 100)
x = np.cos(t)
y = np.sin(t)
z = t

# 绘制曲线箭头
ax.plot(x, y, z)
ax.quiver(x[-1], y[-1], z[-1], x[-1]-x[-2], y[-1]-y[-2], z[-1]-z[-2], length=0.5)

# 设置坐标轴标签
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')

# 显示图形
plt.show()
