Well, I think I've figured out the problem. I didn't notice it before but on the mxml chart I was using "dataUnits" and on the AS chart I was using "labelUnits". It looks like labelUnits are the culprit because when I switched the AS to this, if finally rendered correctly. I haven't tested it extensively, but for now, it looks like that is working.
