bar with asymmetric error bounds in Matlab

问题

I want to draw a bar with error bounds like this http://www.mathworks.ch/matlabcentral/fileexchange/9377-barerror. There are many scripts to do this around that combine bar() and errorbar(). But all I found can only deal with symmetric errors. Can anyone show me how to add asymmetric error bounds like errorbar(X,Y,L,U) but on bar, not on curve? Thanks.

You can plot errorbars over your bar chart:

 data = 1:10;
 eH = rand(10,1);
 eL = rand(10,1);

 figure;
 hold all;
 bar(1:10, data)
 errorbar(1:10, data, eL, eH, '.')
