继续向for循环中的图形添加子图

import matplotlib.pyplot as plt

fig, ax = plt.subplots()

for i in range(3):
    ax = fig.add_subplot(1, 3, i+1)
    # 在子图中进行绘图操作

ax.plot(x, y)

import matplotlib.pyplot as plt

fig, ax = plt.subplots()

for i in range(3):
    ax = fig.add_subplot(1, 3, i+1)
    ax.plot(x, y)

plt.show()
