subploting the cells from arrays

 for k = 1:63
data = thething{:,1}(:,4)
subplot(7,9,k)
stem(data)
end

these my codes. thething is 63 cells each with different numbers of cells in it. I would like to collect the forth line of data to draw 63 plot. Matlab saying there are 63 results but can not form plots. How can I do?
