Matlab Errorbarlogx
type the following at the MATLAB prompt, I get a an errorbar with a log x axis:x = 1:100; y = sin(x); e = std(y)*ones(size(x)); errorbar(x,y,e) set(gca,'xscale','log') However, the errorbars of the first point in the resulting figure extend much farther than the other errorbars. I would like a function that can account for the logrithmic X-axis and make all of the errorbars have a uniform width. 1 Comment Show all comments Ohad BarSimanTov Ohad BarSimanTov (view profile) 0 questions 0 answers 0 accepted answers Reputation: 0 on 27 Jul 2016 Direct link to this comment: https://www.mathworks.com/matlabcentral/answers/99844#comment_381798 This is what I got after using others comments, here and stack overflow.errorbar(X,Y,E,'bo','linewidth',2) c=get(gca,'Children'); for i=1:length(c); set(c(i),'XData',get(c(i),'YData'),'YData',get(c(i),'XData')); end; axis([10^-5 10^-3 0.4 1]) % This is just to set the (Y and X) axis (flipped) set(gca,'xscale','log'); % set X log scale view(-90, 90) % Swap the axes if you want Y log scale (you can ignore from here on) set(gca, 'ydir', 'reverse'); % Reverse the y-axis (Optional step) if true % code endThis image is is for X log (ignoring the last two lines)This image is for errorbar Y log including the last two linesI hope that helps.

This results in the plot attached as an image, which obviously isn't working.I've also tried errrobarlogy, which produces literally the same plot.

This doesn't seem to work: figure; hold on; errorbar(x,y,ebar); semilogy(x,yfitted); Instead of semilog plot I get a linear plot. What should I be doing differently? math matlab plot graphing share|improve this question asked Aug 23 '10 at 17:53 AndyL 6,347103466 add a comment| 2 Answers 2 active oldest votes up vote 5 down vote accepted error bar matlab try h = errorbar(x,y,ebar); set(get(h,'Parent'), 'YScale', 'log') or ax = axes(); errorbar(ax, x,y,ebar); set(ax, 'YScale', 'log'); share|improve this answer edited Aug 23 '10 at 18:15 answered Aug 23 '10 at 18:08 Marc 2,73221634 sort of works but it screws all of the errorbars up.. e.g. it fails to draw some of the vertical lines –AndyL Aug 23 '10 at 20:47 2 As you probably realize, you can't take the log of 0 or a negative number –Marc Aug 23 '10 at 22:37 add a comment| up vote 3 down vote This is what the documentation says. "If you attempt to add a loglog, semilogx, or semilogy plot to a linear axis mode graph with hold on, the axis mode will remain as it is and the new data will plot as linear" I would suggest that you just reverse the order of your plotting, that is. semilogy(x,yfitted); hold on; errorbar(x,y,ebar); share|improve this answer answered Aug 23 '10 at 18:11 Ghaul 3,14111122 I had tried that first. It doesn't actually work. :/ –AndyL Aug 23 '10 at 20:50 I'm on MATLAB R2009a –AndyL Aug 23 '10 at 20:50 It should work. Are you writing >>figure; >>hold on; before using semilogy? If you
