Animation using multiple frames/figures in for loop

I have the for loop that plots different frames of data, but I am trying to update all my frames in one figure to create an animation. All I get is 20 separate figures (which is how many frames I have).

frame = 20; 

% Load density data
n = load([Dir '/ne' num2str(frame) '.txt']); %this is my total denisty
% Load X and Y data
XX = load([Dir 'X.txt']);
YY = load([Dir 'Y.txt']);


for i=1:1:frame
    figure
    n = load([Dir '/ne' num2str(i) '.txt']);
    %plot
    pcolor(XX,YY,n); 
    shading flat; 
    colormap inferno; 
    colorbar;
    hold on;

end

frame = 20; 
% Load density data
n = load([Dir '/ne' num2str(frame) '.txt']); %this is my total denisty
% Load X and Y data
XX = load([Dir 'X.txt']);
YY = load([Dir 'Y.txt']);

figure

for i=1:1:frame

    n = load([Dir '/ne' num2str(i) '.txt']);
    %plot
    pcolor(XX,YY,n); 
    shading flat; 
    colormap inferno; 
    colorbar;
    drawnow
end

The best option would be to follow as discussed in the given link:

Thanks! This works!
