Some advice...

1. People who too often complain that they are beginners, are likely to 
remain beginners forever. Beware.

2. If you expect to use matplotlib (or plotly, or pyqtgraph, etc.) 
frequently, master Numpy, or sooner than you think, you will suffer 
very, very much.

3. My previous example was loop-less; this is one of many advantages of 
Numpy. But you can do it in the orthodox way as well.


*from random import random as rn
import matplotlib.pyplot as plt
n=20
nan=float('nan')
a=[rn() for k in range(n)]   # just a silly random example

for j in range(n-2,0,-2):
a.insert(j,nan)# insert your Nans in such a way
plt.plot(a)
*
