Alternatively, it is not necessary to change the dataset size.
Given y and x, you create two new variables:
gen y1 = 0 in 1
replace y1 = y[1] in 2
gen x1 = 0 in 1
replace x1 = x[1] in 2
line y1 x1 || line y x
Admittedly, you still have to mess around
with legends, line styles etc. So either
you alter your data a little, as above or
below, or you use -scatteri- as earlier
suggested.
