The easiest way to do this is to plot that line,

If you just want the error bars and not lines between them, give it a plot format that only plots points, like r.: bar([a,b,c]); hold on errorbar([a,b,c],[std_a,std_b,std_c],'r.'); share|improve this answer answered Sep 16 '14 at 12:26 nkjt 7,32251528 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

% x = [1,2,3,4,5,6]; y = [2,4,6,8,9,12]; sy =[0.6,0.2,0.4,0.3,0.5,0.4]; % % Now to plot this data I would use the errorbar function (note this function is slightly different % in MATLAB, but it should work similarly). % h1 = errorbar(x,y,sy) % % The above statement is good for most older Octaves, but the recent version % of Octaves have the annoying "feature" of connected the lines of the % error bars (something that no researcher would ever want -- after all, % then why have error bars?). The FMT should handle this, but errobar() % doesn't use the FMT correctly, so the following two lines will fix this. % set(h1,"marker","+") set(h1,"linestyle","none") % % Of course this doesn't work unless you returned handle h1 % % % wpolyfit will be used which is a special optional package for Octave (go to packages and pick Optim -- % note that the Windows binary (from sourceforge) normally comes with this package -- though you have to % select octave forge when you install it) % wpolyfit allows for the error to be used as a weight. There are better ways to do this, but for this % course, this is sufficient. The function wpolyfit is similar to polyfit where a vector is returned % with the coefficients of the polynomial and a structure is returned that includes the Cholesky % factors of the Vandermonde matrix plus other information that is used to create the errorbar on the fit % (as opposed to the error on the data itself). % [p,s] = wpolyfit(x,y,sy,1) % % polyconf is used to get the values of y and sy for the MODEL (not the data). % ci is confidence interval (remember we discussed that?) method which is % appropriate for error bars in the physical sciences. % [yn,syn] = polyconf(p,x,s,'ci') % % Now I continue the graphing. Plotting the model over the data. And making the graph pretty. % You can do different things here depending on YOUR data. % hold on plot(x,y,'b+;The data;') plot(x,yn,'gd-;Linear model;') xlabel('X-data (Size of the {\alpha} tiger)') ylabel('Experiment data with error {\sigma}') title('x versus y showing that y is linearly dependent on x') % % Return handle h2 so you can change the color of the model errorbars, to be different then from % the data errorbars % h2=errorbar(x,yn,syn) set(h2,"color","green") set(h2,"marker","+") % % Let's neaten up a bit % axis([0,7,0,14]) Finally we have a graph with the data, the error on the data, the model of the data (linear fit in this case), and the error on the model data.
