st: problem with labels of multiple over()s in graph hbar

[Dino Gibertoni <dino.gibertoni2@unibo.it>]

dear statalisters,
I have to produce several hbar charts where I want to stack the
ordinal answers to 5 different items, each of them categorized for
another variable.
It all works fine when this last categorical variable has only two
classes. If I take the same code and change only the reference to the
variable, using a variable with 3 classes, the labels of the 2 -over-
variables overlap.
This is the piece of code related to the graph, where PRESIDIO is the
3-class variable:


graph hbar (mean) D2_1-D2_5, over(PRESIDIO, label(labs(vsmall)) gap(*.6)) ///
    over(j, relabel(1 `" "dagli operatori della" "sua U.O." "' ///
                                             2 `" "dagli operatori
del" "Dip.to Chirurgico" "' ///
                                             3 `" "dai membri della
sua" "categoria prof.le" "' ///
                                             4 `" "dallo staff della"
"Direzione Aziendale" "' ///
                                             5 "dai cittadini/utenti")
label(labs(small)) )  ///
  stack scheme(sj) percentages cw nolabel graphr(c(white))  ///
  ylabel(0 20 "20%" 40 "40%" 60 "60%" 80 "80%" 100 "100%") ytitle("") ///
  legend(rows(1) symx(*.4) span tsty(smbody) nobox ///
  label(1 "per nulla") label(2 "poco") label(3 "abbastanza") label(4
"molto") label(5 "moltissimo")) ///


I'm inclined to think that this could be a bug; does someone have any
suggestion?
Thanks for your attention,
