Python 在散点图中设置errorbar样式失败

我需要创建一个带有错误条的散点图，并配置错误条样式。虽然这对简单绘图功能有效，但对散点图无效：

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

df = pd.DataFrame(np.random.random(15).reshape(5, 3),
                  columns=['x', 'y', 'yerr'])

# WORKS
df.plot(x='x', y='y', yerr='yerr', capsize=10, capthick=10, linestyle='None')
plt.show()

# WORKS
df.plot.scatter(x='x', y='y', yerr='yerr')
plt.show()

# FAILS
df.plot.scatter(x='x', y='y', yerr='yerr', capsize=10, capthick=10)
plt.show()

上面的代码给出了最后一个plot命令的以下错误：

类似于

fig，ax=plt.subplot（）

，

ax.errorbar（df['x']，df['y']，df['yerr']，fmt='o'，capthick=10，capthick=10）

，类似于

fig，ax=plt.subplot（），
ax.errorbar（df['x']，df['y']，df['yerr']，fmt='o'，capthick=10，capthick=10）
？
