A simple and quick way is to fill a rectangle before you start your plot.
x1 = 0.4; x2 = 0.9;
y1 = 1; y2 = -1;
figure(1)
fill([x1 x1 x2 x2],[y1 y2 y2 y1],'r')
axis([0 2 y2 y1]),hold on
t = 0:1e-3:2*pi;
plot(t,sin(10*t))

if you have multiple x values that need to be patched (i.e.several sets of two data points that need to be discretely patched on a time scale) is there a function that can help with this
