Clara doesn't mention which version of Stata is being used. However, in 
every version I have used, the answer is the -xline- statement, which is a 
little bit more complicated in Stata 8 than in Stata 7, because there is a 
greater choice of line formats. In Stata 8, see online help under -help 
added_line_options-. In Stata 7 or below, see on-line help under -help graph-.

I hope this helps.
