Plot with variable background color

I'm plotting line charts with the x-axis representing the timeline. Some of the dataranges should be marked as unreliable. For showig this it would be great to change the background color over these x-ranges to some bringt yellow or red. Is there an option of doing that?

I know that could us gscatter instead of gplot for using colors. But then only the data is colored and not the background and I don't get linecharts but point charts. Colored data would be an acceptable alternative, but I need line charts.

It is always possible to make a filled polygon plot. Try,

a = 0:0.1:1;
b = a;
figure;
plot(a,b,'r');
hold on;
x = [0 0 1 1 0];
y = [0 1 1 0 0];
h = fill(x,y,'g');
set(h,'FaceAlpha',0.1); % or alpha(h,0.1); would also work
