MATLAB: Display value in plot “Groups Bars”

Question

Hi

In the following code:

How can I show each bar its value

clc, clear
y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
bar(y)
for i=1:1:length(y)
    text(i:i,y(i)',num2str(y(i)' ,'%0.2f')),'HorizontalAlignment','center','VerticalAlignment','bottom';
    box off ;
end

I will note that I have the 2019 version that does not support the above solution

TNX 🙂

xtips1 = b(1).XEndPoints;
ytips1 = b(1).YEndPoints;
labels1 = string(b(1).YData);
text(xtips1,ytips1,labels1,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')

How to label bar heights for non-stacked bar plots

This demo adds labels above each bar.

To add the labels at the top but within the bars, change VerticalAlignment to Top.

y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
h = bar(y);
% Get bar centers (tested in 19a)
xCnt = get(h(1),'XData')' + cell2mat(get(h,'XOffset'))'; % XOffset is undocumented!
% Apply labels
text(xCnt(:),y(:),compose('%d',y(:)),'HorizontalAlignment','center','VerticalAlignment','bottom')
% Adjust height if tallest label is outside of axes
ylim([min(ylim),min(ylim)+range(ylim)*1.05])
