Side-by-side (instead of overlapping) error bars

Question

I have some data and I am plotting the mean at each time point with error bars showing the standard deviation.

I can simply use errorbar(x, y, err) and this works fine for a single line. However, if I want to plot multiple data sets in the same plot, the error bars overlap and it looks bad:

I would like the error bars to be side by side. So each regression is slightly displaced from the previous ones. Is there an easy way to do this that I am overlooking?

Answer 1

You can add a known or random offset to the x values of your points, e.g.

s=[-1 1]; 
offx = x + rand(size(x)).*0.01.*x.*s(randi(2,size(x)))
errorbar(offx, y, err)

Alternatively, R2018b introduced the stackedplot function. It's not what you were asking about (horizontal offset), but it might be useful (vertical offset, like subplot).
