Hi, I need to plot a40x40 squared heatmap animation, Something like the attached figure but a dynamic one where the color keep changing "randomly".
FYI, I have a system with 5 states 0, 1, 2, 3, and 4. Its a conditional system (Markov Chain) which can transit from one state to another. I need to present this concept in a visibly attractive way. That is why I want to plot this animation. Looking for suggestions and help. Thanks

You could also use scatter with a superlarge markersize.
figure;
colormap([1 1 1;1 1 0;1 0 0;0 0 1;0 1 0]);
[X,Y] = meshgrid(1:40,1:40);
h = scatter(X(:),Y(:),50,randi([1 4],numel(X),1),'s','filled','markeredgecolor',[.5 .5 .5])
ax = gca;
set(ax,'visible','off')
ax.Position = ax.Position ./ [1 0.6 1.2 1.2];
axis equal
for j = 1:100;
h.CData = randi([1 5],numel(X),1);
pause(0.1)
end

What about pcolor?
