Matplotlib with "secondary_y"：如何将图例重新定位到左下角？

import matplotlib.pyplot as plt

fig, ax1 = plt.subplots()
ax2 = ax1.twinx()

ax1.plot(x, y1, 'r-', label='y1')
ax2.plot(x, y2, 'b-', label='y2')

lines, labels = ax1.get_legend_handles_labels()
lines2, labels2 = ax2.get_legend_handles_labels()
ax2.legend(lines + lines2, labels + labels2, loc='lower left')

import matplotlib.pyplot as plt

# 数据
x = [1, 2, 3, 4, 5]
y1 = [10, 20, 30, 40, 50]
y2 = [5, 10, 15, 20, 25]

# 创建图表和子图
fig, ax1 = plt.subplots()
ax2 = ax1.twinx()

# 绘制数据到子图上
ax1.plot(x, y1, 'r-', label='y1')
ax2.plot(x, y2, 'b-', label='y2')

# 合并图例到左下角
lines, labels = ax1.get_legend_handles_labels()
lines2, labels2 = ax2.get_legend_handles_labels()
ax2.legend(lines + lines2, labels + labels2, loc='lower left')

# 显示图表
plt.show()
