Tommy,
The easiest way is probably to provide contourf with x and y arguments
corresponding to the bin centers. The x vector would have an entry for
each column in your Z(x,y), and the y vector an entry for each row.
In [1]:z = rand(10,20)
In [2]:x = 2*arange(20)
In [3]:y = 2*arange(10)
In [4]:contourf(x,y,z)
