I am trying to generate a bar chart using one cell with 3(10*5) random elements as it is illustrated in the ZIMBI.png image
My code is like this:
for i = 1:3
cell_part = abs (randn(10,5))
figure;
bar ( cell_part(1,:))
hold on
% figure;
bar ( cell_part(2,:))
hold on
% figure;
bar ( cell_part(3,:))
hold on
bar ( cell_part(4,:))
hold on
bar ( cell_part(5,:))
cell_total{i}(:,:) = cell_part;
end
figure;
bar(cell_total{1}(:,:)', 'group' )
hold on
bar(cell_total{3}(:,:)', 'group' )
hold on
bar(cell_total{2}(:,:)', 'group' )
hold on
% Unfortunatelly, this code generates the image Cakld.png :
How can I associate the cell position with the bar chart ?

Still no luck with what? Please try to clarify what you are trying to do. Is the key issue just adding tick labels as in the example chart you posted? If so, just following instructions in @Yazan's answer.

A very simple solution is to plot the data directly but after introducing matrices of zeros so that the bars look like they are grouped. See the example below.
clear, clc
close all
% toy data of size 10-by-5
data1 = randi(5, [10 5]);
data2 = randi(5, [10 5]);
data3 = randi(5, [10 5]);
% insert zero matrices
data = [data1; zeros(5, 5); data2; zeros(5, 5); data3];
% plot stacked bars normally
bar(data, 'stacked');
ax = gca;
ax.XTick = [5 20 35];
ax.XTickLabel = {'Data1', 'Data2', 'Data3'};
