How do i add a title and color bar

How do I add a title to this? I thought that I did but it is not showing up on the graph. As well as a color bar and name the x and y axis, and turn off the grid mesh.

    pause(.01);
    hold on
    title('PEC Boundary Condtion')
    colorbar;
    hold off
    grid off
    pcolor(Hz)
