st: My axis(2)-title is ignored when using by() in twoway scatter?

[Kim Lyngby Mikkelsen <epidat@gmail.com>]

Hi,

In  twoway scatter, when using the  by() option, yti("My title",
axis(2)) is innored?
Is there anyway to have the "axis(2)"-titel displayed?

My by-variable is gender, that is, with 2 categories.

My code is:
scatter proportion_m   year_op2 if alder_op10==80, sort msymbol(none)
connect(l) || ///
scatter proportion_m   year_op2 if alder_op10==90, sort msymbol(none)
connect(l) || ///
scatter mean_age_op year_op2                              , sort
msymbol(none) connect(l) yaxis(2) ylab(72(2)78, axis(2)) || ///
, by(gender, legend(off) note("") ti("No. of operations, and mean age
at operation, by gender"))  ///
yti("No. of operations (per 1000)", axis(1)) yti("Mean age at
operation", axis(2))

The axis(2)-title ("Mean age at operation") is ignored!
If I remove the by()-option, both y-titles are displayed!

How can I have it displayed when using the by()-option?

I an using Stata 12, win7
