how do I draw the peak of a 2D shape in one dimension, which is the imagesc code?

With Stockwell transfrom, I have the segmentation of filtered abnormal and normal heart sounds, but I want to draw the peaks in one dimension like the attached figure.

For your data: 50 gives a good estimate

The mean and standard deviation (threshold) values can be computed from your calculated values:

Mean_S = mean(SEenv);            % Mean value of the energy
Mean_S1 = mean(SEenv1);          % Mean value of the energy
STD_S = std(SEenv);                  % Standard deviation of the energy
STD_S1 = std(SEenv1);                % Standard deviation of the energy

@Sulaymon Eshkabilov Thank you very much for your reply. Now what I need to do is how do I draw the vertex of a 2D shape in one dimension, which is the imagesc code?
