如何使用python为同一箭图中的多个箭头添加标签

import matplotlib.pyplot as plt

# 创建一个箭头图
fig, ax = plt.subplots()

# 添加箭头
arrow1 = ax.arrow(0, 0, 1, 1, head_width=0.1, head_length=0.1, fc='blue', ec='blue')
arrow2 = ax.arrow(1, 1, -1, 1, head_width=0.1, head_length=0.1, fc='red', ec='red')

# 添加箭头标签
ax.annotate('Arrow 1', xy=(0.5, 0.5), xytext=(0.2, 0.8),
            arrowprops=dict(facecolor='blue', arrowstyle='->'))
ax.annotate('Arrow 2', xy=(0.5, 1.5), xytext=(0.8, 1.2),
            arrowprops=dict(facecolor='red', arrowstyle='->'))

# 设置图表标题和坐标轴标签
ax.set_title('Arrows with Labels')
ax.set_xlabel('X')
ax.set_ylabel('Y')

# 显示图表
plt.show()
