Re: st: sts graph

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

I will address the second of Anthony's questions.

The tick marks for the -censored()- option of  -sts graph-  are rendered by 
a call to -rspike- but there does not appear to be a way to call 
-rspike-s's options, in this case, -blcolor()-.

Now sts.ado is a fearsome thing to dabble with, and one hesitates, but I 
have nevertheless done so.  I call the "new" program sts_kludge.ado and 
with good reason.

It allows just one more option:   blcolor(-choice of color-)  to render the 
colours of spikes at times of censoring. For example:

sysuse cancer
stset studyt, fail(died)
sts_kludge graph, censored(single) blcolor(green)

A far better approach would be to have a new option associated with 
-censored()-  to allow  multiple options of -rspike- to be invoked (as we 
have the pairs -atrisk- and 
-atriskopts(marker_label_options)-   and   -gwood- and -ciopts()- ). This 
would allow, for example, the use of -mlabcol()- to render the colour of 
the numbers censored.


I will send sts_kludge to Anthony separately - I think it is too much of an 
under-tested beast to let loose.
