shade area between two yline

I want to shade the area between two yline:

p1 = yline(5,'-','color',[177 177 177]./255,'LineWidth',2);hold on 
p2 = yline(4,'-','color',[177 177 177]./255,'LineWidth',2);hold on 
x = 0:2200;
x2 = [x, fliplr(x)];
inBetween = [p1, fliplr(p2)];
fill(x2, inBetween, 'gray');hold on;

Since x2 and inbetween are not in the same size, my code does not work. How can I change it to gt the shaded area?

Thank you for any help

You cannot fill between yline() or xline().

yline() and xline() are reference lines that cross the entire axes and logically continue to +/- infinity. If you pan or zoom, yline() and xline() continue to be shown even if there is no data in the new area.

fill(), however, is always implemented as a closed bounded area -- something that can zoom or pan away.

I suggest you

fill(x([1 end end 1 1]), [4 4 5 5 4], 'gray')

does not work:

Error using fill

Not enough input arguments.

x = sort(rand(1,20));
fill(x([1 end end 1 1]), [4 4 5 5 4], [.8 .8 .8])

Thank you so much Walter! It works well
