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 7,31251528 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.

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 Matlab Plot Error Bars Without Line
