Convert your Treat variable to a factor with appropriate
levels before plotting or (less desirable) use
as.factor(Treat) in place of Treat.

A couple of bits of advice for future posts:
1. We don't have your data, so either provide relevant
    information about it ( str() is useful) or, if
    possible, illustrate your problem with a built-in
    dataset. Or make up some data to illustrate the
    problem.

2. Excise extraneous information from your code;
    here we don't need your ylab, as.table, groups,
    type, auto.key.
