It looks like you can just add normal graph options after your original command. See below for an example:

version 12

sysuse auto, clear

cusum foreign weight, ///

lcolor(black) ///

title("{bf:Title Goes Here}", span c(black)) ///

yscale(r(-15 5)) ///

ylabel(-15(5)5, labsize(small)) ///

xscale(r(1500 5000)) ///

xlabel(1500(500)5000, labsize(small)) ///

graphregion(c(white))

Much appreciated, Cisyk!
