Is there a way to create a lot of graphs for a 4D matrix without coding for a ton of individual graphs?

I have a 4D matrix that I'm trying to create graphs for. There are 4 dimensions, a physical state, two informational states, and time.

I want to make a bunch of graphs within a larger "graph" Basically info state 1 on the y axis and info state 2 on the x axis, but then within that, there are a bunch of graphs with physical state on the y axis and time on the x axis.

Here's an example of one graph:

fivexfive(:,:)=opt(:,5,5,:);
imagesc(fivexfive);
colorbar;
xlabel('Time');
ylabel('State');
set(gca,'YDir','normal');
axis('square')

the second two dimensions range from 1-15 each. So that'd be..... a lot of graphs.

Is there any way to try and make at least a few of them without brute forcing a ton of graphs? If that's not possible that's fine, figured I'd try asking!

how would I use tiledlayout with a bunch of graphs created by a for loop? All of the smaller graphs correspond to specific positions on the xy axes on the larger graph, I don't want them just anywhere.

@Josh I'm having trouble with "Color data must be an m-by-n-by-3 or m-by-n matrix." and also getting " hh = image(varargin{:}, 'CDataMapping', 'scaled');"

That means that its trying to map out the four dimensions, right?

I tried editing it turning current graph into two dimensions like I had previously

currentgraph(:,:)=opt(:,i1,i2,:)

but that didn't seem to help at all

Hi Kitt,

Here is one approach. In the example you are using imagsc plots instead of e.g. 1d plots of some state quantity vs. time, so imagesc is used here. This code thinks about it for a few seconds and then makes 15 figures of 15 miniplots each, one of which is below.

A = rand(100,15,15,100);     % assuming the order is state,info1,info2,time
B = permute(A,[4 1 2 3]);    % put into an easier order, less potential problems for Matlab 
for info1 = 1:15
  figure(info1)
  sgtitle(['inf01  =  ' num2str(info1)])
  info2 = 1;
    subplot(4,4,info2)
    imagesc(B(:,:,info1,info2))
    title(['info2:  ' num2str(info2)])
  for info2 = 2:15
    subplot(4,4,info2)
    imagesc(B(:,:,info1,info2))
    title(num2str(info2))
  end
end
