Plot correct values

[Felipe]

I'm not familiar with numpy, so I can't say what that type is. A short check of some numpy docs makes me assume that it has something to do with the 'relationship' of numpy to C++.
However, it has it's own copy method. originT = t.copy() should provide an independend ndarray.

Wow, thanks, thanks, thanks !!!

That worked perfectly for me. I just add T.copy() and B.copy() to my code and this minor correction solved the problem. Thanks for the patience and help with the solution.
