Hi everyone,

I obtained with the following code the plot for each image of the maximum and minimum distance (I have attached for example 3 plots but in reality there are more)

[max_value max_index]=max(mean(all_maxDist/distance_mm))
[min_value min_index]=min(mean(all_maxDist/distance_mm))
  
m= plot((max_index),max_value , 'ro', 'MarkerSize', 12, 'LineWidth', 2);
% Draw a line from the x-axis up to the max.
line([(max_index), (max_index)], [0,max_value ], 'Color', 'r', 'LineWidth', 2);
n=plot((min_index),min_value , 'ro', 'MarkerSize', 12, 'LineWidth', 2);
% Draw a line from the x-axis up to the min
line([(min_index), (min_index)], [0,min_value ], 'Color', 'r', 'LineWidth', 2);

Now ,I would like to get 2 graphs separately (one for the maximum and one for the minimum) that show me the variations that the maximum and the minimum undergo for each iteration (eventually finding a sort of square wave)

Do you only have the images, or do you have the data that was used to plot them? And from these 3*2 values, what output would you want?

Read about the function stem

x = rand(1,10) ;

[val1,idx1] = min(x) ;

[val2,idx2] = max(x) ;

stem([idx1 idx2],[val1 val2])

xlim([0 10])

KSSV for each iteration I want you to describe me a real trend of the variations and not a stem.

In the end I want to get only one final graph for maximum variations and only one graph for minimum variations.
