You seem to have completely ignored my advice about cutting the code 
down to the minimum amount that demonstrates the error. Okay, that's 
your perogative, but as a volunteer it is my perogative to choose how 
much or how little effort I put into solving your problem for you.

I have neither the time nor the inclination to spend a lot of time on 
this, so I'll just offer one suggestion. According to the error 
traceback, you appear to be running the script from inside either the 
Spyder IDE, or possibly an iPython/Jupyter notebook.

This appears to be the command you are running (inside iPython?):

> runfile('/home/comp/Apps/Python/Plot_T_Data/MultiplePlots_3.py', wdir='/home/comp/Apps/Python/Plot_T_Data')

and the traceback shows a failure relating to iPython and/or Spyder:

It is possible that you have recently updated iPython or installed 
Spyder, and that has broken your script. I recommend that you eliminate 
them from contention, by running your script from the old-fashioned 
Linux commandline. From bash, or some other terminal shell, run:


cd /home/comp/Apps/Python/Plot_T_Data
python3.5 MultiplePlots_3.py


and see if the error persists. If the error goes away, then the problem 
lies in iPython or Spyder.

In a nutshell, based on a cursory look at the traceback, this seems to 
be a problem with your environment rather than your code.

Good luck!
