MATLAB Plus Error Bars? -

how can make matlab error bars go above mean in bar graph or histogram? errorbar function gives symmetric bars

thanks! easy on excel cannot find way conveniently on matlab

use third form of errorbar allows specify both upper u , lower l error bars, , set lower 0:

x = 1:10; y = 10*rand(1,10); u = rand(1,10); l = zeros(size(y));  errorbar(x, y, l, u)
