The following code, using a dataset that is shipped with Stata, combines
three graphs with individual titles and xtitles.  Can you replicate the
problem using this dataset?

sysuse sp500, clear
replace volume = vol/10
gen month = month(date)
sort month
foreach v of varlist volume open close {
by month: egen lo_`v' = min(`v')
by month: egen hi_`v' = max(`v')
by month: keep if _n==_N

twoway rcap lo_v hi_v month || connect volume month, ///
  title("LEGACY=0") xtitle("MAG1") ytitle("PARTIES") legend(off) /// 
  name(lo_legacy, replace)  ylabel(,nogrid) xlabel(1(2)12)  nodraw
twoway rcap lo_o hi_o month || connect open month , /// 
  title("LEGACY=4") xtitle("MAG2") legend(off) yscale(off) ///
  name(med_legacy, replace) ylabel(,nogrid) xlabel(1(1)12) nodraw
twoway rcap lo_c hi_c month || connect close month , /// 
  title("LEGACY=8") xtitle("MAG3") legend(off) yscale(off)  /// 
  name(hi_legacy, replace) ylabel(,nogrid) xlabel(1(1)12) nodraw
graph combine lo_legacy med_legacy hi_legacy, rows(1) ycom
