The easiest way I know is to overlay (or more likely underlay) a -twoway function- plot, e.g.
scatter yvar xvar
becomes
twoway (function x, range(xvar) n(2)) (scatter yvar xvar)
to have the diagonal line underneath, or
twoway (scatter yvar xvar) (function x, range(xvar) n(2))
with the diagonal line on top.

Subject: st: add diagonal line to graph
Hello all,
I want do add a diagonal line to a scatterplot (the main diagonal).
I know how to add a horizontal or vertical line ( - help
added_line_options - ) but I don't know how to add a diagonal line.
Any suggestions?
Thanks in advance,
Falko.
