Cannot create plot using pandas.dataframe.hist() [duplicate]

Question

This is my code:

import pandas as pd
df = pd.DataFrame({'value1': [1, 5, 9], 'value2': [56, 84, 98]})
df.hist()

but no plot popped up, the program just ran and stopped. I'm sure I have all the required packages, and I can plot with matplotlib like:

import matplotlib.pyplot as plt
import pandas as pd
df = pd.DataFrame({'value1': [1, 5, 9], 'value2': [56, 84, 98]})
plt.scatter(df['value1'], df['value2'])
plt.show()

I'm using windows 10 pro, python 3.6.4.

Where are you running the code ?

Do you call plt.show()?

You need to call plt.show() if you run your script from command line:

import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame({'value1': [1, 5, 9], 'value2': [56, 84, 98]})
df.hist()
plt.show()

If you are in a Jupyter notebook, you need turn on a suitable backend such as:

%matplotlib inline
