See the help for -lpoly-, which gives an answer.
You can use -addplot()-.
. lpoly <stuff>, addplot(lpoly <more stuff>)
There is a subtle difference. The outer -lpoly- really is -lpoly- but
the inner -lpoly- is -twoway lpoly-.
If all else fails, -generate- the results from two calls as distinct
variables and then superimpose scatter plots and smooth curves as
desired.

I want to do a graph of two kernel local polynomial smoothing
regressions.
I have done the following:
.lpoly zscoresha2 Ageinmonths if treated==1 [aweight= expweigh],
noscatter ci
.graph copy Graph treated=1
.lpoly zscoresha2 Ageinmonths if treated==0 [aweight = expweigh],
noscatter ci
.graph copy Graph nontreated
.graph combine treated nontreated, ycommon xcommon
But I get two graphs next to each other. I see the same query in
Statalist but for twoway graphs. How can I combine the kernel polynomial
graphs into one?
