```Dear Nick,

Unfortunatelly I don't want to plot the predicted probability but the point estimate of x (which in my case is more than one) and it's confidence interval.
Thank you anyway.

Nikos

This doesn't seem to require any user-written stuff.

I want to plot the estimates and their confidence intervals from two regressions.
This sounds like a job for eclplot (downloaded from ssc).  The code in the end of the email shows how this can be done but the graphs for each regression appear next to each other.
I want to have this in one single graph. I want the estimates from the first regression to appear over those from the second regression.

Is it possible to do something like this in Stata?
