Hi@akhtar,

To plot a graph we generally use matplotlib library. Inside docker matplotlib works in back end. But there is a way to perform matplotlib in front end. Follow the below given steps.

• Download tkinter module.

$ yum install python3-tkinter

• Open your python file and write down the below codes.

import matplotlib
matplotlib.use('TKAgg')
import matplotlib.pyplot as plt
plt.plot()
