MATLAB: Shade area between graphs

areafillgraphsshading

I want to shade the area between these graphs

but this certainly does not do the trick:

fill([t t(end:-1:1)],[y1 y2(end:-1:1)],'y')

I also downloaded and tried "jblill"

http://nl.mathworks.com/matlabcentral/fileexchange/13188-shade-area-between-two-curves

but that did not seem to amend the outcome so far

Try using fill() instead of area():

x = 1 : 300;
curve1 = log(x);
curve2 = 2*log(x);
plot(x, curve1, 'r', 'LineWidth', 2);
hold on;
plot(x, curve2, 'b', 'LineWidth', 2);
x2 = [x, fliplr(x)];
inBetween = [curve1, fliplr(curve2)];
fill(x2, inBetween, 'g');

Try this:

D = load('TE_U.mat');
y = D.TE_U(:,1);
L = D.TE_U(:,2); 
H = D.TE_U(:,3);  %CI values
x = (1:numel(y)).'-1;
figure
plot(x, y, 'k.', 'LineWidth', 2);
hold on
plot(x, L, 'r', 'LineWidth', 1);
hold on;
plot(x, H, 'b', 'LineWidth', 1);
x2 = [x; flipud(x)];
inBetween = [L, H];
fill(x2, [L; flipud(H)], 'g', 'FaceAlpha',0.5);         % Decreasing Transparency Allows Data Behind The Shading To Be seen
xlim([0 200])

And there is a problem we all run into the first time we use fill() :)

x = 1:10;
y1 = rand(1,10)+1;
y2 = rand(1,10)-0.5;
fill([x fliplr(x)],[y1 fliplr(y2)],'c')

The sorting order is important. You want to trace the outside as if you were to walk around your x/y coordinates.
