What is the code to plot several .dat files together?

I have 1000 .dat files and I want to plot graphs from them and save the results in .png format for all the files. How do we do that?

I have the same question.

The answer down here are not working for me.

figure
hold on
datfiles = dir('*.dat');
for K = 1 : length(datfiles)
  data = load(datfiles(k).name); %load just this file
  % Plot the data depending on variables 
end

Thanks. But, I want to store all the plots in .png format and then make an animation of how the system is evolving with time.

I am working on Molecular dynamics simulations. So I have 10000 .dat files which shows the state of the system at different instants and I want to generate a plot of these files and make an animation out of them.

that case...make a .gif file out of your data...check this link: https://in.mathworks.com/matlabcentral/answers/94495-how-can-i-create-animated-gif-images-in-matlab

can you please help me how to sort all the files? My file names are t-0.dat, t-1.dat,t-2.dat,t-4.dat,...t-16.dat,...., t-128.dat,........t-10000.dat. But when I'm using the code to plot the results, it reads t-0, t-1,t-128,t-10000, then t-2,....t-4... like this. I want to get them in order. How do I do it? (I have modified your code a bit to get the plots).

datfiles1 = dir('*.dat');

for k = 1 : length(datfiles)
 data = load(datfiles(k).name);
h=figure;
 scatter(data(:,1),data(:,2),50);
 hold on;
 quiver(data(:,1),data(:,2),data(:,4),data(:,5),0.3);
  end
saveas(h,sprintf('fig%d.png',k));
 hold off;

end

You can try this file exchange function by Stephen Cobeldick:

Thanks. But, I have already tried using natsortfiles,it did not work. I could not apply it properly as I'm new into Matlab. Can you please help me regarding how I should apply natsortfile function here to sort the files?

datfiles = dir('*.dat');
for k = 1 : length(datfiles)
 data = load(datfiles(k).name);
h=figure;
 scatter(data(:,1),data(:,2),50);
 hold on;
 quiver(data(:,1),data(:,2),data(:,4),data(:,5),0.3);
  end
saveas(h,sprintf('fig%d.png',k));
 hold off;

end
