Matplotlib 样式表未应用

我一直在尝试几种样式表，但似乎没有一个适用于画布。这是我第一次使用twinx()所以也许这就是问题所在。我尝试过的代码如下 -

import pickle
import numpy as np
import matplotlib.pyplot as plt

with open("acc.pkl", "rb") as a:
    acc = pickle.load(a)

with open("loss.pkl", "rb") as b:
    loss = pickle.load(b)

x = np.array([point for point in range(100)])

fig, graph_1 = plt.subplots()
points_1 = np.array(acc)
graph_1.plot(x, points_1, 'b')

graph_2 = graph_1.twinx()
points_2 = np.array(loss)
graph_2.plot(x, points_2, 'r')

plt.style.use('fivethirtyeight')
plt.xlabel('epochs')
fig.tight_layout()
plt.show()

样式表参数在使用它们的对象时应用created.

例如。如果你想要给定样式的图形和坐标轴，你需要设置样式表before通过创建它们plt.subplots.

plt.style.use('fivethirtyeight')
fig, graph_1 = plt.subplots()
