There's just no accounting for the taste of some people... Here are

How about adding a kwarg to the signature of the errorbar function,
which defaults to below=True (this would have the default behavior you
want, errorbars below markers, but could be customized).
Then you could add an if clause in the errorbar code which reverses
the order of the calls.
Since noone has done the zordering yet, and this issue has come up
twice in the context of errorbars, it is probably worthwhile to add it
now to the errorbar code.
If I could impose in you one more time Norbert to submit a patch that
allows the user to configure the order using a kwarg, I'll be happy to
check it in.
BTW, Gary, any chance I could persuade you to write a tutorial/guide
to using errorbar / bar / barh for the users guide? barh is in CVS.
If you are averse to latex, you could submit in plain text and I can
convert it. I'm mostly done with the matlab interface section and
have been working on other sections (API) and I am having trouble
motivating myself to finish some of these matlab interface sections.
Since you are the world's expert on matplotlib bar charts, I thought
you would be a good victim, er candidate, to write that section. FYI,
I looked into changing the default meaning of x in the errorbar code
to have it refer to the center, rather than the left, as we discussed.
The problem is, this broke some of the table examples, which are a bit
hairy and written by John Gill, so I put it on the back burner. For
barh, however, I did make the y axis mean the center, since we are all
in agreement that this is the more intuitive behavior.
