I have a sine graph and I want to highlight all along the x-axis and just the [-1,1] region on the y-axis. Is this possible?
This is my code and I would like the bounds between [-1,1] on the y-axis to be shaded some color all along the x-axis. The whole area, not just the peaks and valleys.

% Do you want this?
x=linspace(0,2*pi,101);
y=sin(x);
area(x,y)

This is the next step:
x=linspace(-5*pi,5*pi,101);
KP1=(6*(sin(x)./(x)))+cos(x);
hold on;
plot(x,KP1)
plot([-5*pi,5*pi],[-1,-1],'r');
plot([-5*pi,5*pi],[1,1],'r');
