How to put endpoint on Bar graph

y = [75.8 78.05; 81 80.30; 91 80.78];
b = bar(y);

Hello , I want to add endpoints on each graph. How should I do that?

[Scott MacKenzie]

What do you mean by "endpoints"?

If you mean "error bars", try doc errorbar. And, since you are adding these to bars, you'll need to include linestyle 'none'.

No I mean that I want my values for each Bar graph shows on top of my graphs for example first bar graph is 75.8 and I want this value to be appeared on top of the graph.

OK, got it. I just posted an answer. Good luck.

In R2021b, this is straightforward (and described in Specify Labels at the Ends of Bars).

y = [75.8 78.05; 81 80.30; 91 80.78];

figure
b = bar(y);
for k = 1:numel(b)
    xtips = b(k).XEndPoints;
    ytips = b(k).YEndPoints;
    text(xtips, ytips, compose('%.2f',y(:,k)), 'Horiz','center', 'Vert','bottom')
end

In R2017b, this is a bit more involved —

figure
b = bar(y);
for k = 1:numel(b)
    ctr = bsxfun(@plus, b(k).XData, [b(k).XOffset]');
    ydt = b(k).YData;
    str = compose('%.2f',ydt);
    text(ctr,ydt, str, 'HorizontalAlignment','center', 'VerticalAlignment','bottom')
end

Experiment to get different results.

maybe?

There's a klunky example at the doc for bar, but it is far simpler than the multi-step illustration to write it as

hB=bar(y);
arrayfun(@(h)text(h.XEndPoints,h.YEndPoints, ...
                    compose('%.1f',h.YData), ...
                    'HorizontalAlignment','center', ...
                    'VerticalAlignment','bottom'),hB)

Salt the format string to suit...
