# Plotting a Graph From a Cell Array

I have a cell array, let's call it A, which is a 4 x 4 cell each containing a 10 x 10 numbers from 1 to 5 (the cell array attached):
A = cell(4,4);
Each cell array is like:
I want to plot a graph for each cell (for just one) and all of the cells (for all 16 cell arrays) in separate code that shows how many of the components are 1, 2,3,4 and 5. Essentially a chart similar to (I don't think Matlab can graph such a chart, but something similar):
"A" here is just one of the frame indices (I have to plot multiple cell arrays). Thank you!

First, check out the data:
whos
Name Size Bytes Class Attributes Kappa_x_num 4x4 171264 cell ans 1x30 60 char
Kappa_x_num{1,1}
ans = 10×10 cell array
{'4'} {'4'} {'1'} {'3'} {'1'} {'1'} {'1'} {'1'} {'5'} {'5'} {'5'} {'1'} {'1'} {'3'} {'1'} {'1'} {'1'} {'5'} {'1'} {'1'} {'1'} {'1'} {'5'} {'3'} {'3'} {'1'} {'1'} {'1'} {'5'} {'1'} {'5'} {'5'} {'1'} {'1'} {'1'} {'1'} {'1'} {'1'} {'1'} {'5'} {'4'} {'5'} {'1'} {'4'} {'1'} {'1'} {'1'} {'1'} {'5'} {'1'} {'5'} {'1'} {'5'} {'3'} {'1'} {'1'} {'3'} {'1'} {'5'} {'1'} {'1'} {'1'} {'3'} {'3'} {'1'} {'1'} {'1'} {'5'} {'5'} {'5'} {'4'} {'1'} {'5'} {'3'} {'1'} {'1'} {'1'} {'1'} {'1'} {'5'} {'1'} {'1'} {'1'} {'1'} {'1'} {'1'} {'1'} {'1'} {'5'} {'5'} {'5'} {'1'} {'5'} {'1'} {'1'} {'1'} {'3'} {'1'} {'5'} {'1'}
Then, do some counting:
[m,n] = size(Kappa_x_num);
max_value = 5;
counts = zeros(m,n,max_value);
for ii = 1:m
for jj = 1:n
for kk = 1:max_value
counts(ii,jj,kk) = nnz(strcmp(Kappa_x_num{ii,jj},num2str(kk)));
end
end
end
disp(counts);
(:,:,1) = 61 74 71 71 100 71 71 100 100 6 100 100 100 100 100 100 (:,:,2) = 0 0 0 0 0 0 0 0 0 37 0 0 0 0 0 0 (:,:,3) = 10 1 3 2 0 1 1 0 0 0 0 0 0 0 0 0 (:,:,4) = 5 0 0 2 0 0 0 0 0 56 0 0 0 0 0 0 (:,:,5) = 24 25 26 25 0 28 28 0 0 1 0 0 0 0 0 0
Then, make a stacked bar graph (rearranging the counts to do so):
counts = reshape(counts,[m*n max_value]);
disp(counts);
61 0 10 5 24 100 0 0 0 0 100 0 0 0 0 100 0 0 0 0 74 0 1 0 25 71 0 1 0 28 6 37 0 56 1 100 0 0 0 0 71 0 3 0 26 71 0 1 0 28 100 0 0 0 0 100 0 0 0 0 71 0 2 2 25 100 0 0 0 0 100 0 0 0 0 100 0 0 0 0
figure()
bar(counts,'stacked');
ax = gca();
set(get(ax,'XAxis'), ...
'TickValues',1:m*n, ...
'TickLabel',arrayfun(@(x)sprintf('%d',x),1:m*n,'UniformOutput',false), ...
'TickLabelRotation',0);
set(get(ax,'XLabel'),'String','frame indices');
set(get(ax,'YLabel'),'String','% of points');
legend( ...
arrayfun(@(x)sprintf('''%d''',x),1:max_value,'UniformOutput',false), ...
'Location','EastOutside');
