Hi,

In my GUI I plot multiple graphs in one figure from a matrix (p_matrix) using a for loop. I need to align all the graphs (there are 52 of them) with one maximum point as the reference point, i.e. if I take the index of the maximum of the middle row of my matrix all the other rows maximum points should be at the same index. In some way I need to write a function that takes away some values from either the end or the beginning of the row depending on the maximum point of the row being at a lower or higher index respectively. I have tried with this attempt:

function [p_lined_graphs] = lineGraphs(p_matrix, y_matrix)
  %Function to line up the graphs in order to take a mean value of them later
  %and reducing the noise
p_lined_graphs = zeros(52,120);
for n=1:52
  vector = p_matrix(n,:);
  [maxValueN indexAtMaxN] = max(vector);
  for m=10:110
        if indexAtMaxN ~= indexAtMax
          diffIndex = indexAtMax - indexAtMaxN;
          p_lined_graphs(n,m) = p_matrix(n,abs(m-diffIndex));
      elseif indexAtMaxN == indexAtMax
          p_lined_graphs(n,m) = p_matrix(n,m);
      end
  end
end

, and then I plot the p_lined_graphs in my GUI code but the graphs aren't aligned... Is there anyone that might know what I have done wrong or have another simpler way of aligning the graphs?

Thanks in advance!
