Thank you for your reply Carlos. Sorry for being late to respond,
since I don't have stata on my own computer.
I applied what you suggested, however this is not the case I actually
want to graph .
I want to have percentiles (10th, 20th,..,90th) ordered on the x-axis
and difference of the log wage in 2000 from the log wage in 2005 for
the respective percentile on the y-axis, I'm not interested in the
years between 2000 and 2005.

Greetings
Kisil
