Thank you , Kit. 

If I want to plot the coefficients on years only , not margins'
coefficients, how to do that?

I tried -mat b=e(b)', but coefficients on mvalue and kstock are listed in
data set. How to exclude them?  Thank you.

Best Regards,
Lynn Lee

I run an OLS regression regarding returns to education.There are 20 years,
each year has its coefficient on returns o education. So, I want to plot a
graph, with year on x-axis  , each year's coefficient  on y-axis, and
confidence interval marked on the graph. How to create a data set that store
all coefficients in it, so, I can plot this picture easily? 

set more off
webuse grunfeld,clear
reg invest mvalue kstock i.year
margins year
mat b = r(b)'
svmat b
g yr = 1934 + _n if !mi(b1)
line b1 yr if !mi(b1)

It would be quite straightforward to create this graph with confidence
intervals, using the e(V) matrix returned from -margins- and -twoway rline-.
