Hi Matthijs:
Have you tried
graph export name_of_your_graph.wmf
and then copy and paste into a word document?

Subject: st: graphing results
Dear Stata-listers,
I am trying to graph the results of my regression. I have estimated a
model with quadratic terms and an interaction, as in y=x1 + x1^2 + x2
+ x1*x2. I am trying to plot my results in a graph of y versus x1.
Using -adjust- to keep covariates doesn't do what I need, since it
also sets x1*x2 to the mean of the interaction, rather than x1*(mean
x2).
I can get what I want by plotting it using the -graph twoway function-
command. My current code looks like:
graph twoway scatter y x1 ///
|| function y = _b[_cons] + _b[x1]*x = _b[x1^2]*x^2 + _b[x2]*x2_bar +
_b[x1*x2]*x1*x2_bar ,
where x2_bar is the mean of x2 (in the estimation sample).
However, when imported in a document, the final graph looks coarse:
more like a like a step-function than a smooth line, even when using
2500 points to graph the function instead of the default 300. Is there
a way to get a graph that produces the effect of x1 on y controlling
for covariates, but that looks better than what I have now?
Thanks for helping!
Matthijs
