Try this —

components = {'First Design', 'Second Design', 'Third Design'};

x = [66.5 33.5; 68.7 31.3; 64.9 35.1];

figure

y = bar(x,'grouped');

xtips1 = y(1).XEndPoints;

ytips1 = y(1).YEndPoints;

labels1 = string(y(1).YData);

text(xtips1,ytips1,labels1,'HorizontalAlignment','center',...

'VerticalAlignment','bottom')

xtips2 = y(2).XEndPoints;

ytips2 = y(2).YEndPoints;

labels2 = string(y(2).YData);

text(xtips2,ytips2,labels2,'HorizontalAlignment','center',...

'VerticalAlignment','bottom')

xticklabels(components);

grid on

xlabel ('Design Name','fontweight','bold','FontSize',12);

ylabel ('Penetration Level (%)','fontweight','bold','FontSize',12);

legend('DG', 'PV');

ylim([min(ylim) 75])

This should work in most recent releases. If it does not work in your release (since you did not specify that, I have no idea what it is), there are other options that will work. For the present, see the bar documentation section on Specify Labels at the Ends of Bars for details.

Added —

components = {'First Design', 'Second Design', 'Third Design'};

y = [4.735, 5.230, 4.568];

figure

hb = bar(y,'FaceColor','flat');

xticklabels(components);

C = colororder; % retrieve default colororder vector

hb.CData = C(1:numel(y),:); % use first N

grid on

xlabel ('Design Name','fontweight','bold','FontSize',12);

ylabel ('Total Net Present Cost (M$)','fontweight','bold','FontSize',12);

text((1:numel(y)), y, string(y)+" M$", 'Horiz','center', 'Vert','bottom')

hAx = gca; % get current axes handle

hAx.YAxis.TickLabelFormat = '%0.1f'; % fix up the funky numeric display

% now add a legend by faking another plot that will create the handles

hold on

hA = area(nan(numel(components))); % area will be patch

set(hA,{'FaceColor'},mat2cell(hb.CData,[ones(size(y))],3)); % set areas to match bar face colors

hLg = legend(hA,components);

A lot of thanks, sir,

I'm so much grateful to you. :)

Something like this?

Edit: ah, too slow. Though this very basic approach might work with earlier releases too. You could get() the x coords for the text from the bar handle too

components = {'First Design', 'Second Design', 'Third Design'};

x = [66.5 33.5; 68.7 31.3; 64.9 35.1];

ybar= bar(x,'grouped');

xticklabels(components);

grid on

xlabel ('Design Name','fontweight','bold','FontSize',12);

ylabel ('Penetration Level (%)','fontweight','bold','FontSize',12);

legend('DG', 'PV');

[r,c]=size(x);

ybuff=2;

for ri = 1:r

for ci = 1:c

text(ri+(-0.15+0.3*(ci-1)),x(ri,ci)+ybuff,num2str(x(ri,ci),'%0.0f%%'),...

'HorizontalAlignment','center',...

'VerticalAlignment','bottom')

end

ylim([0 100])

Sir, your graph is so much beautiful. In particular, you mentioned the Percentage Unit. I really appreciate it.

By the way, sir

I needed a favor from you.

As in your previous graph, how can I mention the M$ Unit in this graph?

I have given the code below for ease of understanding.

clc;

close all;

clear;

figure

components = {'First Design', 'Second Design', 'Third Design'};

y = [4.735, 5.230, 4.568];

hB = bar(y,'FaceColor','flat');

xticklabels(components);

C = colororder; % retrieve default colororder vector

hB.CData = C(1:numel(y),:); % use first N

grid on

xlabel ('Design Name','fontweight','bold','FontSize',12);

ylabel ('Total Net Present Cost (M$)','fontweight','bold','FontSize',12);

text(1:length(y), y', num2str(y','%0.2f'),'HorizontalAlignment','center','VerticalAlignment','bottom')

hAx = gca; % get current axes handle

hAx.YAxis.TickLabelFormat = '%0.1f'; % fix up the funky numeric display

% now add a legend by faking another plot that will create the handles

hold on

hA = area(nan(numel(components))); % area will be patch

set(hA,{'FaceColor'},mat2cell(hB.CData,[ones(size(y))],3)); % set areas to match bar face colors

hLg = legend(hA,components);

A simple loop will do

figure()
bv = bar(x,'grouped');
% add the numbers
for ii = 1:numel(bv)
    % the positions
    xLoc = bv(ii).XEndPoints; 
    yLoc = bv(ii).YEndPoints;
    % labels with %
    theLabels = strcat( string(yLoc),'%') ;
    % a vectorised one liner
    text(xLoc, yLoc, theLabels, 'vert','bottom','horiz','center');
end
