2D heat diffusion with convection boundary conditions

The is a follow up to my earlier question on heat transfer in a box of grain.
I observed that the plot from [C,h]= contourf(xx(:,:,g),yy(:,:,g),Tt(:,:,g)); interchanged the bottom side with the left side and the topside with the right. It seems that is the default setting for this command.
However, when I used contourf(x,y,T(:,:,g)) instead, the plot come out right but without contour labels.
I want a contour plot with lables.
What can I do to resolve this problem. I have spent weeks on the issue without success.

Use Transpose int he contour if you do not use meshgrid for gridding the domain.
and for label and having numbers on the lines use below:
contourf(x,y,(u)','ShowText','on')
ylabel('Y')
xlabel('X')
