Hi at all.
I try to use grc1leg with margins plot.
I have the strange error, that I get 3 in stead of 1 legend.
I tried to create an example, that closely follows my data, but I cannot manage with the auto dataset. But the idea is:
The resulting error is in the attached picture. Array
Any suggestions how to overcome the problem are highly appreciated. Thanks!

Code:
gen displ = 0 if displacement < = 100
replace displ = 1 if displacement > = 100
replace displ = 2 if displacement > = 200
label define displ 0 "Moederat" 1 "Medium" 2"Really high"
label values displ displ
gen expensive = 0 if price > 10000
replace expensive = 1 if price >= 10000
quietly: logit foreign c.headroom##c.weight##(1.expensive ib0.displ), ///
noomitted noempty
graph drop _all
quietly: margins, at(headroom=(2(0.5)4) weight=(2500) displ=(0 1 2)) over(expensive)
marginsplot, by(expensive) scheme(s1color) name(m1) nodraw title("weight = 2.5") subtitle(, fcolor(white)) ///
legend(cols(1) size(vsmall)) recast(line)
quietly: margins, at(headroom =(2(0.5)4) weight=(3500) displ=(0 1 2)) over(expensive)
marginsplot, by(expensive) scheme(s1color) name(m2) nodraw title("weight = 3.5")subtitle(, fcolor(white)) recast(line)
grc1leg m1 m2, name(m3, replace) span legendfrom(m1) ycommon
graph display gme
