I am carrying the following regressions:

reg sav_finimp`wave' ib3.group##i.year savimp`wave'
margins 1.group##year, at (group=(1)) saving(m1, replace)
margins 2.group##year, at (group=(2)) saving(m2, replace)
margins 3.group##year, at (group=(3)) saving(m3, replace)

I would like to plot the three different marginal effects in a single plot but specify different plotoptions (for instance, different line colors) and different cioptions for each line. If I use plot#opt and ci#opt and it does not work. Can anyone help? This is what I have tried:

combomarginsplot m1 m2 m3, xdimension(year) title({bf:Probability to save on financial assets}, color(black) size(medsmall)) plotopts(lcolor("146 195 51") mfcolor("146 195 51") mcolor("146 195 51")) ciopt(lcolor("146 195 51")) ciopt(lcolor("200 0 0")) xtitle("Year", height(4.5)) legend(rows(1) order(4 "Bottom 50%" 5 "Middle 40%" 6 "Top 10%"))

Thanks a lot!
