st: -graph bar- label problem

[Sue <likecats@gmail.com>]

Dear Statalisters,

can someone please point out to me what's wrong with the following command?

  graph bar loans, over(year) label(labsize(small)) bargap(2) by(ctype)

It gives me the error "option label() is not allowed". I found the
option in the help file and am puzzled why it's not working.
