How can I add error bars to a stacked bar graph?

I want to add error bars to each section of my stacked bar graph,so that at each line there are error bars for that particular section of the stacked chart. Currently this is what code I am using.

y=[413.71 321.00 133.67 207.50 64.33 126.00; 279.32 190.00 105.33 192.00 54.33 118.33 ];

err=[20.22 58.59 58.05 10.61 8.08 24.58;15.7 36.29 24.79 1.00 14.50 19.60];

bar(y,'stacked');

hold on

errorbar(y,err);

But I am not getting the right result, instead getting something like this:

Can anybody help?

What MATLAB release are you using?

The solution is different for R2014a and earlier releases and for R2014b and later releases.

[Sean de Wolski]

judging from the colormap >= 14b.

R2016b

Did you find an answer for this OP? I am stuck with the same problem, I'm using MATLAB 2014b at my work and MATLAB 2016b. A solution in either versions is sufficient.

[Ellie Parr-Burman]

I'm afraid not! I ended up changing the way I presented the data so didn't need it in the end, sorry I can't be of any help.

If I find a solution, I shall repost on here as I think it will be difficult for me to present the data in a different way.

For the OP: 2 problems: a line connects the error bars and the error bars are in the wrong place. Because of the stacked bars, you must accumulate the y values:

y=[413.71 321.00 133.67 207.50 64.33 126.00; 279.32 190.00 105.33 192.00 54.33 118.33 ];
err=[20.22 58.59 58.05 10.61 8.08 24.58;15.7 36.29 24.79 1.00 14.50 19.60];
bar(y,'stacked');
hold on
errorbar(cumsum(y')',err,'.k');

and the result:

Hello Ellie, I did something like this. I hope it will work for you .I ran a below script on my machine and attached my results. I am not sure about your X data, I assumed it as flowing. I have tried this on R2013b and R2015a Let me know if this is not what you are looking for.....

y=[413.71 321.00 133.67 207.50 64.33 126.00; 279.32 190.00 105.33 192.00 54.33 118.33 ];

err=[20.22 58.59 58.05 10.61 8.08 24.58;15.7 36.29 24.79 1.00 14.50 19.60];

x=[1 2 3 4 5 6;7 8 9 10 11 12];

figure;

hold on

errorbar(x(1,:), y(1,:),err(1,:),'k')

errorbar(x(2,:), y(2,:),err(2,:),'r')

Hello,

Thank you for your answer! That didnt seem to work I'm afraid, instead I got something looking like this:

I'm not sure why it has ended up like this though!

[Evyatar Cohen]

you need to add '.' after you choose your color: (errorbar(x(1,:), y(1,:),err(1,:),'k.')
