assuming agey is integer, and that there are not too discrete values, you 
could
.gen agey2 = agey+0.5
and then use agey as the X variable for SSma, and agey2 as the X variable 
for SSfe

if you vary the offset for age2, you change the spacing between sets of 
data.
?maybe

Dear All,

I drew two graphs using twoway rcap. However, the
confidence intervals overlap and looks confusing. Is
there a way to shift the confidence intervals so the
graph looks more readable? Unfortunately, the jitter
option does not work with rcap. Here is a snippet of
my code:

#delimit ;
tw (rcap SSma_lb SSma_ub agey) (connected SSma_m agey)
   (rcap SSfe_lb SSfe_ub agey) (connected SSfe_m agey)
#delimit ;
