Two further thoughts:
Doing individual graphs and then combining works pretty nicely:
sysuse nlsw88, clear
foreach v in hours wage tenure {
graph hbar `v', over(collgrad) saving(`v')
}
graph combine "hours" "wage" "tenure", col(1) imargin(zero)
You could insist on -xcommon- if you really wanted.
It's not your question, but in almost all circumstances just plotting
the means throws a lot of information away!

Thank you for the explanation. I was afraid that might be the case.
