Multiples traces overlapping on multiple subplots

Hello! I am struggling to create 16 2D subplots based on data in a matrix 16x800x40, which correspond to 16=conditions, 800=bins (points to be included in each trace), 40=repetitions of the same condition. I want to make 40 different traces, all on one of the 16th subplot (so 16 plots, each having 40 traces on). I know I probably need to create some nested for loop but so far could not work it out.

Would appreciate any help!!

this is what I've tried so far....

    for s=1:size(singleTrialTraces,3)
        for k=1:size(singleTrialTraces,1)
        subplot(4,4,k)
        plot(singleTrialTraces(k,:,s))
        axis tight
        hold on
        end
    end

You're missing a hold on to put additional traces on the given axes.

If you were to orient so each 2D array were a plane in the 3D array, then a slice by 40 columns of 800 rows could be done in one call to plot(); it treats each column in a "y" 2D array as a variable automagically.

I think I did put 'hold on', didn't I? Should it be somewhere else? :)

Hmmm, I'm sorry, I'm still lost, could you please explain a bit more? what should I put in the plot() command then? Right now I put 3 variables, which isn't correct... how to do this slicing by 40 cols of 800rows here?

clear
clc
K = rand(16,800,40);

for i = 1:16
	subplot(16,1,i) % subplot(4,4,i)
	for j = 1:40
		plot(K(i,:,j),'b-','linewidth',0.2);
		ylim([-1 2.5])
		hold on
	end
end

Try this

You can try with

subplot(4,4,i)

Thank you :))

just one quick thing for clarity - if i was about to superimpose a mean trace for each of these, do i just need to continue and add another plot command after 'hold on'?

yes,

[VBBV]

clear
clc
K = rand(16,800,40);

for i = 1:16
	for k = 1:800
		KK(i,:) = K(i,k,:);
	end
end

for i = 1:16
	subplot(4,4,i)
	for j = 1:40
		plot(K(i,:,j),'-');
		hold on
	end
	hold on
	kx = mean(KK(i,:))
	kxx = repmat(kx,800,1)
	plot(kxx,'k-','linewidth',3)
end

But you may need to put hold on outside of loop as above

Lovely, thanks so much!
