Hey,
I have three hydrographs with different lenghts
I want to compare these hydrographs and the best way to do so is to overlay the peaks on top of each other or in other words to centralized the peak points in the x axes ( make all the peaks having the same position, lets say 0 in the x axes.
plot(biggest_hg1)
hold on
plot(biggest_hg2)
plot(biggest_hg3)
I have attached the hydroraphs as mat file.
Does some one have any idea how to do it?
Thanks alot in advanced!

load('test.mat');
[~,i1] = max(biggest_hg1);
x1 = (1:length(biggest_hg1)) - i1;
[~,i2] = max(biggest_hg2);
x2 = (1:length(biggest_hg2)) - i2;
[~,i3] = max(biggest_hg3);
x3 = (1:length(biggest_hg3)) - i3;
plot(x1,biggest_hg1);
hold on;
plot(x2,biggest_hg2);
plot(x3,biggest_hg3);
