Jim,

The annotate capability can be quite flexible for the simple task of 
adding a vertical line; in the example below x=50 with xsys='1' implies to 
start at the middle (50%) of the graph area and x2 from 0 to 80 is the 
numerical scale for the vertical axis (ysys='2'). You may need to 
experiment to find the best value for x for the placement of the line to 
show past versus future. You can also easily change the line type, size, 
color, with other options.

DATA lne1; RETAIN xsys '1' ysys '2' when 'a'; LENGTH color $8 ;
x=50 ; y=0 ; function='MOVE'; output;
x=50 ; y=80 ; function='DRAW'; color='black'; line=1; size=2; output;

proc print; run;

proc gchart data=sashelp.class ;
vbar age / discrete sumvar=height type=mean outside=mean raxis=axis1 width
=8 annotate=lne1;
run; quit;

Reference line on PROC GCHART output

Hi, All

I'm having trouble getting GCHART to co-operate. My program so far looks
like this. 

axis1 value=(h=0.5)   ;
axis5 value=(h=0.5) label=none order=('01oct2000'd to '01oct2012'd by
qtr);
proc gchart data=work.c;
    vbar month / type=sum  sumvar=x subgroup=c axis=axis1 maxis=axis5
discrete ;
run; quit;

This is producing a vertical bar chart as I expect. My problem is that I
would like to divide the chart somehow by drawing a vertical reference
line so that the bars for months in the past lie to the left of the line
and the future is to the right. I've tried to do this with options such
as:

href='01sep2009'd lref=2 cref=blue

This produces neither a reference line nor an error message. What am I
doing wrong here?
