I'm not entirely sure what you want here - is it eight points, one for
each year, of the mean of A against the mean of B?  If so, then this
should do it:

	. collapse A B , by(year)
	. gr A B

You can trace out the time path of the points by sorting in date order
and the connecting the dots:

	. sort year
	. graph A B , c(l)

If that's not what you want, maybe you could clarify?
