Plot a line in specific coordinate(survival plot)

Hi, I want to plot a line in a specific value of x axis in a survivalplot, I tried to use an annotate data to do it. As you can see in my annotation data, that I call "anno", I using the 'LINE' function, but it is not working the way I want! I want to use my data values in the coordinates of the line, but when I put any drawspace with exception of the "GRAPHPERCENT", the function apparently does not work, any idea of what is wrong with my script? Here is my sas code:

data sp;
	set sashelp.BMT;
run;


proc sgrender data=sp template=Stat.Lifetest.Graphics.ProductLimitSurvival; run;


ods document name=MyDoc(write); 
proc lifetest data=sashelp.BMT plots=survival(cb=hw test); 
	ods output survivalplot=sp; 
	ods select survivalplot; 
	time T * Status(0); 
	strata Group; 
run; 
ods document close;

proc document name=MyDoc; 
	list/levels=all; 
quit;

proc document name=MyDoc; 
	ods output dynamics=outdynam; 
	obdynam \Lifetest#1\SurvivalPlot#1; 
quit;

data anno;
	 length label $100 function fillcolor linecolor $25;
	 retain drawspace 'datavalue' linethickness 3 display 'ALL'
	 widthunit 'data' heightunit 'data' anchor 'left';

	Function ='LINE'; x1 =	500;	y1 = 0.2;	x2 = 500;	y2 = 0.8; linecolor='black'; fillcolor='black';*drawspace='datavalue';
	output;
run;


proc print noobs; 
run;


%ProvideSurvivalMacros

%macro StmtsBeginGraph; annotate; %mend; 

%CompileSurvivalTemplates



proc template; 
	source Stat.Lifetest.Graphics.ProductLimitSurvival / file='temp.tmp'; 
quit;



data _null_; 
	infile 'temp.tmp'; 
	input; 
	if _n_ = 1 then call execute('proc template;'); 
	call execute(_infile_); 
	if _infile_ =: 'BeginGraph' then bg + 1; 
	if bg and index(_infile_,';') then do; 
		bg = 0; 
		call execute('annotate;'); 
	end; 
run;


data _null_; 
	set outdynam(where=(label1 ne '___NOBS___')) end=eof; 
	if nmiss(nvalue1) and cvalue1= '.' then cvalue1= ' '; 
	if _n_ = 1 then do; 
		call execute('proc sgrender data=sp sganno=anno'); 
		call execute('template=Stat.Lifetest.Graphics.ProductLimitSurvival;'); 
		call execute('dynamic'); 
	end; 
	if label1 = 'Transparency' then cvalue1 = '0.9'; 
	if cvalue1 ne ' ' then 
		call execute(catx(' ', label1, '=', 
					ifc(n(nvalue1), cvalue1, quote(trim(cvalue1))))); 
	if eof then call execute('; run;'); 
run;

proc sgrender data=sp sganno=anno 
			template=Stat.Lifetest.Graphics.ProductLimitSurvival; 
	dynamic NSTRATA = 3 PLOTATRISK = 0 PLOTHW = 1 PLOTEP = 0 PLOTCL=0 
		PLOTCENSORED = 1 Transparency = 0.9 PLOTTEST = 1 PVALUE = 0.0010059117 
		METHOD = "Product-Limit" XNAME = "T" LABELHW = "95% Hall-Wellner Band" 
		SECONDTITLE="With 95% Hall-Wellner Bands" GROUPNAME = "DiseaseGroup" 
		TESTNAME="Logrank"; 
run;

proc template; 
	delete Stat.Lifetest.Graphics.ProductLimitSurvival; 
quit;

Im following this PharmaSUG2016 documentation:

I'll try to look over what you are doing tomorrow. In the mean time, you should know that this is the latest version of the KM plot modification examples. https://support.sas.com/documentation/onlinedoc/stat/151/kaplan.pdf

In the KM chapter I mentioned, find the section "Adding a Custom Header above the At-Risk Table". It provides a basic illustration of annotation. The text mentions annotation statements. In SG plotting procedures (not relevant here but mentioned to provide context), you provide an annotation data set. In a graph template and SGRENDER, you provide annotation statements.
