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')

Ran in:
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!
% For matlab R2019b or later,
% xCnt = vertcat(h.XEndPoints)';
% 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])

Ran in:
It's much more difficult with categorical variables.
The error is telling you that you can't just apply math to categories. For example, what's small+2?
I suggest you don't use categories and instead, just XTickLabels.
xTickLabels = {'Small','Medium','Large','Extra Large'};
y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
h = bar(y);
set(gca,'XTick',1:size(y,1),'XTickLabel',xTickLabels)
% Get bar centers (rested 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),max(ylim)*1.05])

This is the result I wanted
For me XTickLabelit's is great
thank you very much!
