Follow up questions need to be sent to the statalist and not to
individual members. This is exaplained in the Statalist FAQ:
<http://www.stata.com/support/faqs/res/statalist.html#private>

You need to drop the observations representing the variables you want
to exclude before you call -egen axis = axis(estimate), label(parm)-:

*-------------- begin example -----------------
sysuse nlsw88, clear
logit union married never_married collgrad south
parmest, norestore eform
keep if inlist(parm, "south", "married", "collgrad")
egen axis= axis(estimate), label(parm)


 twoway scatter   axis estimate, ///
            xline(1) ylab(1/3, valuelabel angle(0)) ||    ///
       rcap min95 max95 axis, horizontal               ///
            legend(order(1 "point estimate"            ///
                         2 "95% conf. int.") pos(6))   ///
            xtitle("odds ratio") ytitle("")
 *--------------------- end example ---------------------

Hope this helps,
