ERRORBARLOGX Homogenize the error bars for X-axis in log scale.
ERRORBARLOGX turns the X-axis of the current error bar plot to log scale, and homogonizes the length of the horizontal segements which terminate the vertical error bars.
By default, Matlab's ERRORBAR draws vertical error bars which are terminated by small horizontal segments of uniform length for the X-axis in linear scale. But when turning the X-axis to log scale, these segments become uneven. Using ERRORBARLOGX makes them uniform again.
ERRORBARLOGX(N) specifies the relative length of the horizontal segments, normalized with the total range of the data. By default, N=0.01 is used.
Limitations: ERRORBARLOGX acts only on the last drawn curve. If this curve is not an error bar plot, it won't work.
y=5*(1 + 0.5*(rand(1,20)-0.5)).*x.^(-2);

The image is loglog errorbar, which is I need, but the code is logx error bar, can someone tell how to make the loglog happen?
Thank you so much!
Excellent. Easy to use.
Great, it saved my day!
Thanks a lot!
I love it when someone has made just what I'm looking for! This is what the Matlab File Exchange is all about. Thanks!
Works great. Thanks!
Works great! Just what I needed.
Works with multiple curves in a single plot.
Perfect! Very glad I was able to find such a thing. Makes you wonder why matlab doesn't have it by default
thanks a lot - helped so much!
perfect! thank you very much for this.
Exactly what I need ! Thanks
Worked as described. Thanks!
Commands loglog + hold on + errorbar could do the same action.
Very useful, works pretty fine
I Google-searched for a solution to my problem, found your .m file first, and it works like a charm! Thanks!
When I'm trying to run the example provided, the error bar "cap" length is *not* rescaled. I get the following error message:
"??? Index exceeds matrix dimensions.
On line 40 ==> heb = cd.Children(2); % handle to current error bars"
Any input is welcome!

Amazingly useful, and I'm suprised that there isn't something like this built in (as far as I ahve seen)
