pandas python中特定列的饼图绘制

Question

我有一个数据框 df，它有很多列。在 df["house_electricity"] 中，有像 1,0 或 blank/NA 这样的值。我想根据饼图绘制该列，其中将仅显示 1 和 0 的百分比。同样，我想绘制另一个饼图，其中 1,0 的百分比和空白/N.A 都将在那里。

customer_id	house_electricity	house_refrigerator
cid01	0	0
cid02	1	na
cid03		1
cid04	1
cid05	na	0

#I wrote the following but it didnt give my my expected result
import pandas as pd
import matplotlib.pyplot as plt

df=pd.read_csv("my_file.csv")

df_col=df.columns



df["house_electricity"].plot(kind="pie")

#I wrote the following but it didnt give my my expected result
import pandas as pd
import matplotlib.pyplot as plt

df=pd.read_csv("my_file.csv")

df_col=df.columns



df["house_electricity"].plot(kind="pie")

Answer 1

尝试

df["house_electricity"].drop_na().value_counts().plot(kind="pie")
