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 Y = 1.2, error bars matlab 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 service.

of data or the deviation along a curve. errorbar(Y,E) plots Y and draws an error bar at each element of Y. The error bar is a distance of E(i) above and below the curve so that each bar is symmetric and 2*E(i) long. errorbar(X,Y,E) plots Y versus X with symmetric error bars 2*E(i) long. X, Y, E must be the same size. When they are vectors, each error bar is a distance of E(i) above and below the point defined by (X(i),Y(i)). When they are matrices, each error bar is a distance of E(i,j) above and below the point defined by (X(i,j),Y(i,j)). errorbar(X,Y,L,U) plots X versus Y with error bars L(i)+U(i) long specifying the lower and upper error bars. X, Y, L, and U must be the same size. When they are vectors, each error bar is a distance of L(i) below and U(i) above the point defined by (X(i),Y(i)). When they are matrices, each error bar is a distance of L(i,j) below and U(i,j) above the point defined by (X(i,j),Y(i,j)). errorbar(...,LineSpec)
draws the error bars using the line type, marker symbol, and color specified by LineSpec. h = errorbar(...) returns handles to the errorbarseries objects created. errorbar creates one object for vector input arguments and one object per column for matrix input arguments. See errorbarseries properties for more information. Backward Compatible Version hlines = errorbar('v6',...) returns the handles of line objects instead of errorbarseries objects for compatibility with MATLAB 6.5 and earlier. See Plot Objects and Backward Compatibility for more information. Remarks When the arguments are all matrices, errorbar draws one line per matrix column. If X and Y are vectors, they specify one curve. Examples Draw symmetric error bars that are two standard deviation units in length. X = 0:pi/10:pi; Y = sin(X); E = std(Y)*ones(size(X)); errorbar(X,Y,E) See Also LineSpec, pl
