Changes in coefplot

[Joerg Eulenberger]

Dear Statalisters,

I want to create a Graph like this:

sysuse auto, clear
egen std_price= std(price)
egen std_mpg= std(mpg)
egen std_headroom= std(headroom)
egen std_weight= std(weight)
forv s = 1/5 {
quietly mean std_mpg std_price std_headroom std_weight if rep78==`s'
estimate store m`s'
}
coefplot  m1 m2 m3 m4 m5,  xline(0)   ci(95 box) ciopts(recast(. rbar) barwidth(. 0.35) color(. white))

Now I want two small changes:

1. I want the means and ci’s of rep78 for each variable on the same vertical height. (not vertically offset)
2. I want letters ( A, B, C, D, …) as meanmarkers.

Any ideas? Thanks a lot,
Jörg
