st: sts graph: setting line style with multiple groups

[Michael McCulloch <mm@pinestreetfoundation.org>]

Hello Statalist members,
In the following -sts graph- command, the display produces a solid line for both groups 1 and 3, even though I've specified "." for the -lpattern- suboption.

Any suggestions on how to get each plotted line to have its own -lpattern- would be greatly appreciated.

sysuse cancer.dta
replace drug=4 in 1/10
tab drug
sts graph, by(drug) saving("km", replace ) tmax(120) ///
	title("Stage I") ///
	legend(	label(1 "1") ///
			label(2 "2") ///
			label(3 "3") ///
			label(4 "4")) ///
	plot1opts(lpattern(1) lcolor(black)) ///
	plot2opts(lpattern(-) lcolor(black)) ///
	plot3opts(lpattern(.) lcolor(black)) ///
	plot4opts(lpattern(_) lcolor(black)) ///
	xtitle("Survival time in months") graphregion(margin(tiny)) ///
	l2title("Percent surviving") xmtick(0(12)120) xlabel(0 12 24 60 120) censored(single) ///
	risktable(, order(1 "1" 2 "2" 3 "3" 4 "4") rowtitle(, ///
            justification(left)) title(, at(rowtitle)))
