Draw vertical line on gplot graph

[Char]

I am attempting to draw a line from the top of the graph to the bottom.  I am using the floor and ceiling of the minimum and maximum values and, not surprisingly, it's not going to the edge of the graph.   

PROC SQL;

CREATE TABLE ANNO AS

SELECT DISTINCT IMPLEMENTATION_DATE AS ID, floor(min(dpaid)) as min, ceil(max(dpaid)) as max

FROM PERM.all_lcd

where KEY = "&_KEY";

QUIT;

data anno1;

length color function style $8 text $12;

retain xsys '2' ysys '2';

set anno;

function='move'; x=id; y =min; output;

function='draw'; x=id; y =max; color='MAROON'; line=2; output;

function='label'; size=1.2; style='arial'; text=' Date LCD '; position='3'; output;

function='label'; size=1.2; style='arial'; text=' Implemented'; position='6'; output;

run;

I'm guessing I need to change my y values but I don't know what to.  Any help is appreciated.

Thanks!

Ah - never mind.  I just had to change ysys from '2' to '1'.
