Pycharm does not show plot

Question

Pycharm does not show plot from the following code:

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

ts = pd.Series(np.random.randn(1000), in         


        

Answer 1

With me the problem was the fact that matplotlib was using the wrong backend. I am using Debian Jessie.

In a console I did the following:

import matplotlib
matplotlib.get_backend()

The result was: 'agg', while this should be 'TkAgg'.

The solution was simple:

1. Uninstall matplotlib via pip
2. Install the appropriate libraries: sudo apt-get install tcl-dev tk-dev python-tk python3-tk
3. Install matplotlib via pip again.
