Let’s say that I have a column of 3600 different values i y axis. And 3600 seconds in x axis. These values in y axis are stresses applied to a material and they change in amplitud. How do I make a Rainflow chart and histogram?

在 MATLAB Online 中打开

% Sample time-history data with 3600 values

data = rand(1,3600);

% Convert the raw data into rainflow cycles

[cycles,mn,mx] = rainflow(data);

% Plot the rainflow cycles

plot(cycles);

% Create a histogram of the data

histogram(data);

Thank you for your answer. Now I want to extract data from the histogram into a table. For example I want to show for a certain x value we have a certian y value etc. I would appreciate your help. :)
