Without reading your code, if I had a problem like yours, I would 
eliminate all code except that directly concerned with plotting, even 
using simple fake data if necessary. Once that works you know that the 
Plot code works correctly. Then I would add a bit of your real code, try 
the plot again, and add more and more real code. I have had to do this 
many times and eventually I succeed.

I have encountered situations where some simple code looked perfect on 
the screen but did not work. Then when I retype the whole thing all over 
again, it works, even though the good and the bad code looks identical. 
The only thing I can think of is that somehow one or more invisible 
characters got mixed in.

Good luck with fixing your problem.
