How do i fix the Colorbar scale when i run an animation?

this is the part of code for plotting. does the colorbar could be set up outside my 'for' loop?

 for i8 = 1:1000:length(t);

    delete(findobj('tag','Update'));
    grid on
    axis([0,2*b,0,2.2,min(min(dy))-0.1,max(max(dy))*1.2]);
    hold on
    surf([0.3,0.2+b],[dx,dx],[dy(:,i8),dy(:,i8)],'tag','Update','LineWidth',2);
    if abs(max(dy(:,i8))-max(max(dy)))<=0.001;
        caxis = [0,max(max(dy))];
        hold on
        c = colorbar;
        c.Label.String = 'Displacement(inch)';

    end
    pause(0.0000001)
 end

Before the hold on,

caxis([0,max(y(:))])

Note by the way that you are setting the limit by the maximum of y, not by the maximum that you will plot, as you only plot one in 1000

thx for reply. i test your method by re-set caxis by:

caxis([0,1000]);

However, it seems like the colorbar still change all the time when the displacement change in my animation.
