There isn't a good / convenient way to do this with the current  version of 

It is possible to add a property to the error bar handle that sets the width of 
the bars. If you like this idea, please open a "feature request" in the bug 

If you're inclined to modify the sources to do this, 

        (1) scripts/plot/errorbar.m: Needs to have its doc-string modified.
        (2) scripts/plot/private/__errplot__.m: Is where the changes need to be
