Hi Sandeep,

As per my understanding, you want to extract the data from a .csv file and store in the MATLAB variable and then plot it.

Here’s a sample MATLAB code to perform the same.

%store the table in data     
data = readmatrix('data.csv'); 
[r, c] = size(data);   
%Setup figure                
figure;                      
hold on;                    
for i = 1:c                  
    plot(data(:, i))        
end                             
%labels and legends can also be added
hold off;
