I use -twoway line- with a thick but relatively opaque line because I wanted to indicate a certain level/benchmark in -twoway scatter- with the -by- option.
But I end up getting ghost "markers" in the thick line. Here is a contrived example to illustrate.
And here is the graph it creates
The "ghost" markers in the line appear as darker circles, e.g., at Headroom = 2.0 in the graph on the right (and other intermediate points in the line).
Is there some way to eliminate the darker shading? Or perhaps some other way to create a similar shading effect in a graph?
Thank you,

Code:
sysuse auto.dta, clear
keep if strpos(make,"Buick") | strpos(make,"Datsun")
gen benchmark = 3 if strpos(make,"Buick")
replace benchmark = 4 if strpos(make,"Datsun")
sort foreign headroom
twoway (scatter rep78 headroom, ylabel(1(1)5) xlabel(1(1)5) ) ///
(line benchmark headroom, lwidth(vvvthick) lcolor(red%20) ), by(foreign)
