在我的 Pycharm 中，为什么 df.plot() 没有出现在 PyCharm 中？

Question

I have the below pandas code, I want to plot() to display the image, but PyCharm do not shows up.

import numpy as np
import pandas as pd


date1 = pd.date_range('20190114', periods=6)

df = pd.DataFrame(np.random.randn(6, 4))  # shape(6, 4)
print(df[0])

df[0].plot()

In my Pycharm why the df.plot() do not show up?

Answer 1

Try:

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

date1 = pd.date_range('20190114', periods=6)

df = pd.DataFrame(np.random.randn(6, 4))  # shape(6, 4)
print(df[0])

df[0].plot()
plt.show()

Answer 2

I'm not quite sure if this is what you want but there you go:

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

date1 = pd.date_range('20190114', periods=6)

df = pd.DataFrame(np.random.randn(6, 4))  # shape(6, 4)
print(df)

plt.plot(df)
plt.show()
