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?

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.

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

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
