Hi all,
Please I need someone to help me shade the minimum and maximum limits of my data.
I tried this code but it didn't work
load('Data1.mat')
T=Data1
T=[aa v Vn Vx]
figure
hold all
%plot(T(:,1),T(:,2),'.-r'); % median
%plot(T(:,1),T(:,3),'.-g'); % min
%plot(T(:,1),T(:,4),'.-k'); %max
x2 = [T(:,1), fliplr(T(:,1))];
idx = [T(:, 4), fliplr(T(:,3))];
fill(x2, inBetween, 'g');
Thank you.

Ran in:
flip up down instead of flip left right since they are column vector.
load('Data1.mat')
x2 = [T(:,1); flipud(T(:,1))];
idx = [T(:, 4); flipud(T(:,3))];
fill(x2, idx, 'g');

Alternatively, this works. we use patch and that also allows us to manipulate colour ntesnisty of the shaded area.
T=Data1
T=[aa v Vn Vx]
figure
hold all
plot(T(:,1),(T(:,4),'-k');
plot(T(:,1),T(:,3),'-r');
patch([T(:,1); flipud(T(:,1))],[T(:,3); flipud(T(:,4)], 'g', 'FaceAlpha',0.2, 'EdgeColor','g');
plot(T(:,1), T(:,2), 'r')
hold off
