Unable to hold subplot inside for loop

hold on
subplot(3,4,12)
for zz=1:I
    fg=dual_history{zz}; plot(fg(1,:))
end

I have a cell array. Each matrix inside the cell has size 48 by 1001. I want to plot every matrix in thecell array in a subplot. I use the above code but only one matrix (actually, I think only one row of that matrix) is plotted. If I use the code without subplot, it works perfectly fine but then I get a normal plot and not a subplot. Is there any solution to this? Please let me know. Thank you very much!
