Frequency plot for extreme value analysis

Hi there,

I have obtained my extreme value analysis and I would liike to plot frequency plot like the one below in MATLAB:

I have attached my results as well. If someone could help me with that, I would appreciate it.

Regards,

Ali

Hi @Ali Saremi,

To create the frequency plot, we can start by using `readtable` to read the CSV file as follows:

data = readtable('EVA Results.xlsx'); 

Next, we extract the variables and use `hold on` to plot multiple graphs on the same plot. Initially, we plot a histogram, followed by the frequency graphs using the `plot` functions:

figure; 
hold on; 
histogram('BinEdges', intervals, 'BinCounts', frequency, 'DisplayStyle', 'stairs', 'LineWidth', 1.5); 
plot(intervals(1:end-1), wei2_mom, '-r', 'LineWidth', 1.5); 
plot(intervals(1:end-1), wei2_ml, '-g', 'LineWidth', 1.5); 
plot(intervals(1:end-1), wei2_lmom, '-b', 'LineWidth', 1.5); 

The results obtained using this code are as follows:
