How to plot shaded confidence interval?

Hey,

I am struggling to plot the shadded confidence interval. I have 3 variables saved in Mat. File( attached), which include mean value, lower bound and higher bound coressponding to mean value. This is what I have done so far, but it doesnot plot the shaded region.

x=1:1290;

x=x';

y=TE_U(:,1);

L = TE_U(:,2);

H= TE_U(:,3); %CI values

plot(x, y, 'k.', 'LineWidth', 2);

hold on

plot(x, L, 'r', 'LineWidth', 1);

hold on;

plot(x, H, 'b', 'LineWidth', 1);

x2 = [x, fliplr(x)];

inBetween = [L, H];

fill(L, H, 'g');

xlim([0 200])

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])

producing:
