How to plot shaded confidence interval?
显示 更早的评论
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:
