在python中，如何绘制一个有两行的图，让一行从X轴的值n开始？

import matplotlib.pyplot as plt

fig, ax = plt.subplots()

x = [n, n+1, n+2, ...]  # X轴的值
y1 = [y1_1, y1_2, y1_3, ...]  # 第一行的Y轴的值
y2 = [y2_1, y2_2, y2_3, ...]  # 第二行的Y轴的值

ax.plot(x, y1, label='Line 1')
ax.plot(x, y2, label='Line 2')

ax.legend()  # 添加图例
ax.set_xlabel('X')  # 设置X轴标签
ax.set_ylabel('Y')  # 设置Y轴标签

plt.show()

import matplotlib.pyplot as plt

fig, ax = plt.subplots()

n = 5  # 起始值
x = [n, n+1, n+2, n+3, n+4]  # X轴的值
y1 = [1, 2, 3, 4, 5]  # 第一行的Y轴的值
y2 = [6, 7, 8, 9, 10]  # 第二行的Y轴的值

ax.plot(x, y1, label='Line 1')
ax.plot(x, y2, label='Line 2')

ax.legend()
ax.set_xlabel('X')
ax.set_ylabel('Y')

plt.show()
