st: RE: sts graph: specifying line pattern options - addendum

["Philip Ryan" <philip.ryan@adelaide.edu.au>]

Michael,

You could also bypass the problem with -sts graph- by constructing the K-M
plot yourself:

sts gen surv=s
separate surv, by(drug) 
graph twoway line surv1 surv2 surv3  studytime,  ///
 sort connect(J J J) lpattern("."  "-"  ".-.") lwidth(medthick medthick
medthick)

Subject: st: sts graph: specifying line pattern options

Greetings,
In v9 of Stata, I used to specify line pattern options in -sts graph-.  
In the example that follows, one group would be plotted in a solid  
line, one in dash, and one in long dash. All in black:

*** begin example
clear
sysuse cancer.dta
stset studytime, failure(died)
version 9: sts graph, by(drug) lpattern(l - _) lcolor(black blue red)
*** end example

In v11, -lpattern()- needs to be contained within option -plotopts-,  
but in this example below, all  three groups have the same line  
pattern and color:
. sts graph, by(drug) plotopts(lpattern(l - _) lcolor(black blue red))

I tried "formula", but this makes all three groups
sts graph, by(drug) plotopts(lpattern("l - _") lcolor(black blue red))

Any help would be appreciated,
