错误：模块'pandas'没有属性'df1'

Answer 1

您的意思是pd.DataFrame。

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

df2=pd.DataFrame({'Jan':np.random.randint(0,5,size=5),
            'Feb':np.random.randint(0,5,size=5),
            'Mar':np.random.randint(0,5,size=5),
})
df2.plot(kind='bar',stacked=True)
plt.legend(loc='upper left')
plt.show()

评论后编辑：

data = {'Company Name':['GE', 'EON', 'NGP']
        , 'Sale1_percentage':[30, 23, 27]
           , 'Sale2_percentage':[28, 38, 29]
           , 'Sale3_percentage':[45, 44, 31]} 

df1 = pd.DataFrame(data) 

print(df1)

df1.plot(kind='bar',stacked=True)
plt.legend(loc='upper left')
plt.show()
