I have the same problem
try this
1) add this line first
%matplotlib inline
import matplotlib
import matplotlib.pyplot as plt

2) delete this line from your cod.....matplotlib.use('Agg')

3) save the result into png file
plt.savefig('D:\data\mygraph.png')

another solution

import sys
import matplotlib
matplotlib.use('Agg')
....
import matplotlib.pyplot as plt
....
#Two lines to make compiler able to draw:
plt.savefig(sys.stdout.buffer)
sys.stdout.flush()
