You already know the upper/lower error bounds, and just want to draw them on the graph? I don't know the exact answer off the top of my head, but I think you would get some good ideas by looking at the file errorbar.m Have you searched the user-contributed files and "solution search" at www.mathworks.com? That's also a good source for things which you think "surely somebody has wanted to do this before"!

I'd like error bars on each bar like this (or similar at your discretion): I have the means: ff = Medical eq Patient Hygiene Near bed Far bed Direct 1.2759 0.9253 0.6092 1.0460 1.3276 Housekeeping 1.0833 0.2500 error bar on 0.5833 2.1667 1.3333 Mealtimes 0 0.3000 0.7000 1.4500 0.5000 Medication 0.3694 0.7838 0.8919 1.5495 1.0541 Misc 0.1059 0.1294 0.4118 0.8000 0.8353 Personal 0.0370 0.4074 0.8148 1.2593 0.7037 the standard deviations ee = 2.0411 1.1226 0.8378 1.5007 1.3776 1.3114 0.4523 0.6686 2.4058 1.1547 0 0.7327 1.3803 2.1392 0.6070 0.7499 0.9186 1.0300 1.2844 1.3062 0.4371 0.3712 0.7605 1.0212 0.6699 0.1925 0.6939 1.6417 3.5582 1.5644 instead I get this: by using: bb=bar(ff'); hold all data=repmat([1:6]'*ones(5,1)',1,1) er=errorbar(data, ff, ee, '.')

Any workaround? matlab share|improve this question asked Mar 30 '13 at 9:47 HCAI 3432828 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted It's really not that crazy! You can just use errorbar with the data that you have readily available. This code computes the correct locations, by adding 1 for every group and 1/7 for each bar within a group. for i = 1:5 j = 1:6; x = -0.5 + i + 1/7 * j; errorbar(x, ff(j,i), ee(j,i), '.'); end Results in: (Leaving ou
isn't too tough. First of all, we'll replace the standard deviation we plotted in the previous recipe with a standard error of the mean (SEM). The idea behind this being that if two 95% SEMs don't overlap then you likely have a significant difference on your hands. I say "likely" because in practice this may depend on other things, such as multiple comparisons. We'll use the e SEM_calc.m function introduced in the SEM recipe. %Same data as before data.bob=randn(1,12)+0.66; data.alice=randn(1,15)+1.2; data.rufus=randn(1,8)-0.8; data.uma=randn(1,21)+1.4; data.bozo=randn(1,10)+5; %Calculate means and SEM in the same manner as previously f=fields(data); for ii=1:length(f) mu(ii)=mean( data.(f{ii}) ); sem(ii)=SEM_calc( data.(f{ii}) ); end %Plot all this in a pretty way H=bar(mu); set(H,'EdgeColor','b','FaceColor',[0.5,0.5,1],'LineWidth',1.5) set(gca,'XTickLabel',f) ylabel('Truffles per cubit') hold on for ii=1:length(f) plot([ii,ii],[mu(ii)-sem(ii),mu(ii)+sem(ii)],'-k','LineWidth',4) end hold off Ok! We've blasted through all the stuff in the last recipe, but this time we've used the SEM instead of the SD. Let's overlay the raw data now. It's good practice to overlay raw data when it is reasonable to do so. If you have vast quantities of data (large sample sizes and dozens of groups) then overlaying the raw data points may make the plot impossible to read. In most cases, however, overlaying the data is possible. It's always worth doing because this way you are showing yourself (and your reader) all of the information. hold on for ii=1:length(f) tmp=data.(f{ii}); %temporarily store data in variable "tmp" x = repmat(ii,1,length(tmp)); %the x axis location x = x+(rand(size(x))-0.5)*0.1; %add a little random "jitter" to aid visibility plot(x,tmp,'.r') end hold off Despite overlaying all of the da
