制作Excel数据的直方图时的ValueError

Question

我正在尝试制作excel数据的直方图。我使用了以下代码：

import pandas as pd
import matplotlib.pyplot as py
data=pd.read_excel('file.xlsx',header=1, parse_cols="Q")
plt.hist(data, bin=10)
plt.show()

但它给出了这个错误：

Traceback (most recent call last):

  File "<ipython-input-1-0ffa7ab287c3>", line 4, in <module>
    plt.hist(data, bin=10)

KeyError: 0

这就是我的数据的样子

有没有人知道如何解决这个问题？
