Re: [Matplotlib-users] TypeError: Dimensions of C (645, 536) are incompatible with X (538) and/or Y

Yeah it makes sense. I still can't find the bug, which it most likely is. I will keep looking and see what i find.

Thanks for the help

Yes, pcolormesh and pcolor use the same argument parsing and checking. 
They actually *want* N+1, M+1; the *acceptance* of N, M is a matlab-ism that is convenient for quick looks, but is also a potential source of error.

The OP has an X dimension of M+2, which indicates an error earlier in the OP's code.
