The easiest way to do this is to plot that line, then use hold to plot the others:figure(1) errorbar(Traffic, EngsetPb, barvector) hold on plot( ... the rest ... ) hold off grid Hypothetical variables here. 5 Comments Show 2 older comments Star Strider Star Strider (view profile) 0 questions 6,544 answers 3,168 accepted answers Reputation: 17,038 on 25 Jul 2014 Direct link to this co

I have data, series(y), which I have to plot against (x). Also I have the standard deviation values for each data point of (y). Now I have to plot these series highlighting the error bars. How can I do that? The data is in a text file sorted in columns as: X = -50, -49, -48, -47....0....1, 2, 3, 4, 5....till 50 http://stackoverflow.com/questions/7879449/how-to-plot-an-error-bar-plot-with-standard-deviation-values-in-matlab Y = 1.2, 1.0, 1.1, 1.9, 1.3..... Standard deviation = 0.6, 0.5, 0.3, 0.6, 0.6..... Also, how do I control the ticks and appearance property for these kinds of graphs? matlab plot share|improve this question edited Dec 14 '12 at 18:42 Peter Mortensen 10.3k1369107 asked Oct 24 '11 at 17:32 user1011350 26113 3 As a side note: For saving/exporting figures, check out the excellent export_fig from FileExchange. It saves nice looking figures by default, without having to tweak a bunch of the figure properties yourself. –John Colby Oct 24 '11 at 17:58 add a comment| 1 Answer 1 active oldest votes up vote 9 down vote x = 1:0.1:10; y = sin(x); e = 0.1 * randn(length(x), 1); errorbar(x,y,e) set(gca, 'Xlim', [4 10]) set(gca, 'XTick', 4:2:10) See also get(gca) and get(gcf) for other properties to change. For help on any of these functions, do, for example, help errorbar. share|improve this answer answered Oct 24 '11 at 17:47 John Colby 13.8k23556 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 servic

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","+") % % L
