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 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 matlab plot error 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 10.2k1369107 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 13.7k23556 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. Note that these instructions only work for Octave. MATLAB does not
