Hi Joseph,
From your question I understand that you have a CSV file containing multiple columns and you want to plot data from these columns.
You can read the CSV file first and then get the required columns and plot these against each other.
Use readmatrix function in MATLAB to read the CSV file and the extract the columns based on your requirement.
data = readmatrix('file.txt');
% for eg, if we want the first and second column to be plotted against each
% other
axes_x = data(:,1);
axes_y = data(:,2);
plot(axes_x, axes_y);
Hope it helps!
Thanks
