Color by group scatter plot

[Arthur Langlois-Droal]

I want to plot multiple scatter plots upon grouping them by category, here by region. However, I want to be able to arbitrarily change the line color and marker of any of the individual graphs, whether as measured by the graph position, the subset of the data (i.e., region == "West")...etc. For example, here the color line is orange and the marker is o, but how would I go about setting marker(+) and color(green) for the subplot where region == "West" ?

sysuse census, clear

scatter pop divorce, by(region, ixaxes) sort connect(l) msymbol(o) ytitle("") color(orange)

Thanks in advance!

See the command sepscatter from SSC: https://www.statalist.org/forums/for...lable-from-ssc. Otherwise, you can do the following:

sysuse census, clear
local colors green orange blue red
local symbols oh + D T
separate pop, by(region) veryshortlabel
separate divorce, by(region) veryshortlabel
local command
forval i=1/4{
    local command `command' scatter pop`i' divorce`i', sort connect(l) lc(`=word("`colors'", `i')') lp(solid) mc(`=word("`colors'", `i')') ms(`=word("`symbols'", `i')') ||
}
set scheme s1mono
twoway `command', by(region, ixaxes leg(off) note(""))
