For adding lines, my quick and dirty solution is to plot x against x and
not label the line, using twoway command. This will give you a 45 line.
You can define some variables to give you any slope you want. For example,
if you wanted a 30 line.

gen h=_n;
gen v=.3*x;

Here is the command:

twoway (scatter y x, sort) (line v x),  legend(off);

Perhaps there is a more elegant way.
