[英]How to make stacked bar plot for Pandas DataFrame work?
I have a DataFrame, consisting of several timeseries like this: 我有一个DataFrame,由几个时间序列组成,如下所示:
import pandas as pd
df = pd.DataFrame({'A': [10, 20, 30, 40],
'B': [15, 17, 16, 12],
'C': [33, 11, 49, 20]})
df
A B C
0 10 15 33
1 20 17 11
2 30 16 49
3 40 12 20
Plotting a simple line diagram works like a charm, even with automatic legend: 绘制简单的线图就像魅力一样,即使使用自动图例:
df.plot()
In the documentation, if find the optional parameter stacked
(boolean, default False) with the description "If True, create stacked bar plot. Only valid for DataFrame input" . 在文档中,如果找到可选参数
stacked
(boolean,默认为False),其描述为“如果为True,则创建堆积条形图。仅对DataFrame输入有效” 。 So I type 所以我输入
df.plot(stacked=True)
and receive the following TypeError message: 并收到以下TypeError消息:

Did I call the function in a wrong way or is this a bug? 我是以错误的方式调用该函数还是这个错误?
df.plot(kind='barh', stacked=True)
