AttributeError: 'function' object has no attribute 'bar' in pandas
提问by Baktaawar
I have a pandas data frame which is a pandas data frame type as shown below
我有一个Pandas数据框，它是Pandas数据框类型，如下所示
type(df)
Out[176]:
pandas.core.frame.DataFrame
But when I try to use any plotting functions on this data frame like bar graph it gives an error as follows;
但是，当我尝试在此数据框（如条形图）上使用任何绘图函数时，会出现如下错误；
df.plot.bar()
AttributeError: 'function' object has no attribute 'bar'
Not other function like box plot or hist is also not working. Any idea why?
不是箱线图或 hist 等其他功能也不起作用。知道为什么吗？

If you have specific columns in mind that you want to plot, you can try:
df.plot(x='x', y='y', kind='bar')
如果您有要绘制的特定列，可以尝试：
df.plot(x='x', y='y', kind='bar')

Interesting, for me it works very well:
有趣的是，对我来说它工作得很好：
df = pd.DataFrame({'ab': {0: 31196, 1: 18804}})
print df
ab
0 31196
1 18804
#New in version 0.17.0.
df.plot.bar()
Another option:
另外一个选项：
df.plot(kind='bar')
EDIT (by discussion in chat):
编辑（通过聊天讨论）：
I think you need boxplot:
我认为你需要boxplot：
#filter columns
df = df.drop(['city','last_trip_date','phone','signup_date','user_red'], axis=1)
print df
Retained avg_dist avg_increase avg_price avg_value pct \
0 1 3.67 1.1 5.0 4.7 15.4
1 0 8.26 1.0 5.0 5.0 0.0
2 0 0.77 1.0 5.0 4.3 0.0
trips_in_first_30_days weekday_pct
0 4.0 46.2
1 0.0 50.0
2 3.0 100.0
df.boxplot(by='Retained', layout=(7,1), figsize=(5,15))
