Thread Subject: Filling the area between two curves

I am trying to fill/shade the area between several groups of two lines on a time series graph. I am Using MatLab 7.7.0 (R2008b). Can anyone please help.

Hi Group,

I am also having this problem/challenge:

It must be possible. I've tried plotting two area() graphs in the same
axis and coloring the face of the lower one white, but it doesn't look
good and it is a hack.. Anybody have any ideas?

Thanks!

Hi,
 I think this works.
y = [0:0.2:10];
x1 = y.^2+2;
x2 = 3*y-3;
% The variable with higher y value should be plotted first. For more complex situation plot all the
% curves first to check which one has higher y values
figure
h2 = area(x2,y,'FaceColor',[.5 .9 .6],'EdgeColor','b', 'LineWidth',2);
% plot the x2 and x1 variables. x2 variable is marked by blue line
hold on
h1 = area(x1,y,'FaceColor',[.9 .85 .7],'EdgeColor','y','LineWidth',2);
hold off
% The area between x2 and x1 variable is shaded green and the area between
% x =0 and x1 variable is shaded brown.
% The problem with this code is that you can set any transparency because
% it is actually shading the area between x2 and x =0 and then x1 and x = 0.
