Dear Rick-

Have you tried ecl plot?  For this routine, you need a database with
four variables:  the value of your dots (y-axis), the lower and upper
bounds of your confidence intervals (mu-1.96*se, mu+1.96*se), where mu
is the value of your dots, and an id variable that gives a unique
identifier for each observation (x-axis).  This plot gives a number of
options for endcaps, appearances of the lines or bars for confidence
intervals, etc.

Here's some sample code:

input B cil ciu parmid
-.1556 -.217  -.094 1
-.058 -.090 -.025 2
.041 .001 .081 3
.139 .066 .212 4
eclplot B cil ciu parmid, ///
	rplottype(rspike) ///
	ciopts(lc(black)) ///
	estopts(col(black) msiz(small)) ///
	title("Effect of Income on Evaluations of Democracy" "at Different
Levels of Satisfaction with Democracy", col(black)) ///
	xtitle("Level of Satisfaction with Democracy") ///
	xlabel(1 "Not at All" 2 "Not Very" 3 "Somewhat" 4 "Very") ///
	xsca(titlegap(5)) ytitle("Coefficient for Effect of Income" "on
Evaluation of Democracy") ///
	yline(0, lw(medthick) lc(black))

I just saw that it looks like you had solved the problem otherwise,
but this is still a pretty useful command.  Hope it helps.

Best,
David
