st: How can I make a graphic of regression results using only significant effects?

["Alvaro Zevallos" <azevallos@grade.org.pe>]

Hi All,

I am working in a model that uses an interaction between two dummies 
variables. The command that I am using is:

--  xi3: reg Y   i.dummy1*dummy2  X

and the results are

dummy1                      (Significant)
dummy2                      (Significant)
dummy1* dummy2       (Not significant)
X                                 (Whatever)

Then, I use the -  postgr3 - command for make a graphic of the results but 
Stata shows me a figure that consider the not significant effect (the 
interaction). How can I avoid that Stata considers this effect? I read the 
help file but I don't see an option for that

Thanks a lot!

Alvaro Z.
