To find the actual integer that corresponds to 9/11/2001, enter the command:

display mdy(9,11,2001)

Now, I believe you will get a vertical line plotted on your graph if you
include

xline(15229)

since 15229 is the "date" integer corresponding to the date 9/11/2001.

Hope this helps.

This is for Stata 7.....

man grsym

reveals that you can add horizontal lines using yline and rline whilst
vertical lines can be drawn using xline and tline.

Hope thats of some help
