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?

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
