Definitely datetime objects:

    if xtime:
        min_x = datetime.datetime(9999, 12, 31, 23, 59, 59)
        max_x = datetime.datetime(1970, 1, 1, 0, 0, 0)
        def parse_x(x):
            try:
                return dateutil.parser.parse(x)
            except ValueError:
                print >> sys.stderr, "Can't parse", repr(x), "as a timestamp."
                raise
        ...

You're suggesting that I shouldn't have to do anything with formatters
and locators if my X values are datetime objects?  Maybe I should
simply scrub any locator/formatter initialization altogether.  When I
first started this little tool I used a FuncFormatter which (unknown
to me) performed about like the AutoDateFormatter without the "Auto"
part.  It simply selected the X axis format based on the range of the
data.
