Do you mean something like this:
sysuse auto,clear
qui  parmby "regress mpg gear", by(fore) label norestore
replace fore = fore+.1 if parmseq == 2
replace fore = fore -.1 if parmseq == 1
eclplot estimate min95 max95 fore , hori ///
	ylabel(0 1, labgap(*15) notick  nogrid) ///
  	ymlabel( -.1 "Gear Ratio" .1 "Intercept" .9 "Gear Ratio" 1.1
"Intercnet", ///
                angle(h) grid)
