I have two sets of data (after processing the e in the code in 2 ways). When I do the same thing with each of them, one of them produces what I want and one of them doesn't. I am perplexed exactly what the issue could be. The only thing different is the data between them. But the subplot b and c titles completely screw up and end up inside the previous plots somehow, as you can see from the 2 files with self-explanatory names that are produced from the code.
