plot multiple lines in one graph using data from sorted files

I have a bunch of ascii files named 'Moo_1.dat','Moo_3,dat'... till 'Moo_300.dat'. within each file there are four columns, they don't have any labels/names on the top of each column. I wanna plot the third column of each files into one graph using for loop. How can I do that?

You are only asking about the plotting, so I assume you already know how to load your data. I use dlmread since that will read an ASCII-delimited file of numeric data into a matrix, which sounds like what you want to do.

How are you assigning this data to a variable? Is your loading of the data also occurring inside the for loop? I assume so. Otherwise, the loop would be unnecessary.

I'd probably do something like this:

filename = ["Moo_1.dat";"Moo_2.dat";"Moo_3.dat"];
...
for fnum = 1:length(filename)
    Moo = dlmread(filename(fnum));
    ...
    hold on
    plot(Moo(:,3))
    hold off
end

Look at the documentation of hold for more details and options.
