The reason Stata wants to label the x axis on each of the graphs, is
that each bar graph may have a different range on the x axis. You can
see this in the following example:
. use http://www.stata-press.com/data/r8/auto1
. graph bar mpg, by( headroom ) over( foreign )
An alternative is to use -twoway bar-.
. bysort headroom foreign: egen mean=mean(mpg)
. twoway bar mean foreign , by( headroom ) xlabel(0 "Domestic" 1
"Foreign") xscale(r(-.5,1.5)) yscale(r(0,30)) xtitle("") ytitle("mean of
mpg") barwidth(.6) plotregion(margin(zero))
