[Sulaymon Eshkabilov]

Here is one example how to get such bar chart:

y = [12 22 23; 21 25 26; 24 18 19; 22 17 15];
bar(y,'stacked')
legend({'Set # 1', 'Set # 2', 'Set # 3'}, 'Orientation','horizontal')
ax = gca;
ax.YGrid = 'on';
ax.GridLineStyle = '--';
xlabel('Orders')
ylabel('Magnitude')

y = [12 22 23; 21 25 26; 24 18 19; 22 17 15];
h = bar(y,'stacked'); % capture the bar objects into variable 'h'
legend({'Set # 1', 'Set # 2', 'Set # 3'}, 'Orientation','horizontal')
ax = gca;
ax.YGrid = 'on';
ax.GridLineStyle = '--';
xlabel('Orders')
ylabel('Magnitude')

% change the bar colors:
h(1).FaceColor = 'k';
h(2).FaceColor = [0 0.5 0];
h(2).FaceColor = 'm';
