从python数据框绘制图

Question

我想将该数据框转换为该数据框并使用沿x轴更改的数据框的日期绘制matplotlib图

Answer 1

Use df.T.plot(kind='bar') :

import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame.from_csv('./housing_price_index_2010-11_100.csv')

df.T.plot(kind='bar')
plt.show()

you can also assign the transpose to a new variable and plot that (what you asked in the comment):

import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame.from_csv('./housing_price_index_2010-11_100.csv')

df_transposed = df.T
df_transposed.plot(kind='bar')
plt.show()

both result the same:
