My color map and color bar are not representing the same colors?

I have a code something like this.
[m,n]=meshgrid(0:el_length_x:XL, 0:el_length_y:YL);
figure
surf(m,n,D3);
colormap jet;
hc=colorbar;
set(hc, 'ylim', [0 1])
shading interp

my D3 values are closer to 0 as you can see in the figure 2.
My colorbar shows only the brown but my plot shows different colors. How to avoid this?

It is because your values are close to 0 but you set colorbar limit from [0 1].
That below set would work but I personally don't set colorbar limits and leave it Matlab to do it automatically.
set(hc, 'ylim', [0 0.1])
