如何在matplotlib中使用更高精度(或更多小数位)的yaxis上的值进行绘图？

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 10, 100)  # x轴数据
y = np.sin(x)  # y轴数据

fig, ax = plt.subplots()

ax.yaxis.set_major_formatter('{:.2f}'.format)  # 保留两位小数

ax.plot(x, y)
plt.show()

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 10, 100)
y = np.sin(x)

fig, ax = plt.subplots()
ax.yaxis.set_major_formatter('{:.2f}'.format)
ax.plot(x, y)

plt.show()
