I wouldn't support this advice, but because then you would have (to
remember) to delete the extra observation too. If you did want to extend
the line beyond the range, as is quite reasonable, then -twoway
function- is indeed the better solution.

If ever you did want to extend the range with Nick`s solution, e.g. to
include the origin:
*************
sysuse auto, clear
set obs 75
replace price = 0 in 75
tw scatter weight price || /*
*/ line price price, sort
*************

Ah, there's a good tip, and it avoids having to set the range with
function
y=x. Thank you.
