Uenohara-san,
The legend includes all values of the -over- variable (including
missing) by default, as you can see by trying this command:
. graph pie if rep78<4, over(rep78) by(foreign)
I do not know if this behavior is intended. You can suppress the
unwanted legend entries with the -legend(order)- option.
. graph pie, over(rep78) by(foreign) legend(order(1 2 3 4 5))
