Help with Side-by-side Barchart Template

Hello, Trying to create a barchart that has statistics printed at the bottom. The below template is close to what I need but the gridded layout gives each row the same area in the graph, creating a lot of white space and causing the graph itself to be very small. I tried switching to a lattice in order to assign row weights since I receive an error (ERROR 685-580: This statement cannot be used in this block. - which I believe is caused by nesting a datalattice within a lattice. Any ideas? I am using SAS 9.2 2M3. Thanks.

proc template;
define statgraph cmtrix;
begingraph / includeMissingDiscrete=true border=false;

layout gridded;

layout datalattice columnvar = qstest/ ;

layout prototype;

barchart X=week y=mean / group=week barlabel=false orient=vertical name='a';

scatterplot X=week y=mean / yerrorlower=lclm markerattrs=(size=0) errorbarattrs=(thickness=1) datatransparency=0.6;

endlayout;

entry halign=left 'N';

blockplot x=qstest block=n12 / display=(values label) valuehalign=center label='Week 12' repeatedvalues=true;

blockplot x=qstest block=n24 / display=(values label) valuehalign=center label='Week 24' repeatedvalues=true;

blockplot x=qstest block=n36 / display=(values label) valuehalign=center label='Week 36' repeatedvalues=true;

discretelegend 'a' / title='Week: ' across=3 border=false;

endlayout;

endgraph;
end;

run;

data means;

input qstest $ week mean n12 n24 n36;

datalines;

a 12 3 3 4 6

b 12 2 2 5 4

c 12 3 4 6 6

d 12 3 8 5 3

a 24 8 3 8 5

b 24 4 9 9 6

c 24 6 8 3 7

d 24 9 9 2 9

a 36 8 3 8 5

b 36 4 9 9 6

c 36 6 8 3 7

d 36 9 9 2 9

;

run;

ods listing close;

ods rtf style=GraphRTF startpage=no;

ods select sgrender;

ods noptitle;

ods graphics on;

proc sgrender data=means template="cmtrix"; run;

ods graphics off;

ods rtf close;

ods listing;

Update:

In case it is unclear - I am trying to produce a graph that is similar to:

But with summary statistics printed underneath the graph like in:

Is there something I am not providing in order to facilitate help? I have simplified and rephrased the problem to hopefully make things more clear.

I assume something is not quite right with your data, but maybe I don't understand it.

The reason for me saying this is because I can't figure out what the n12, n24 and n36 variables represent.

Anyhow, here is a code that will create a table of your data below the plot.

proc template;

define statgraph cmtrix;

begingraph / includeMissingDiscrete=true border=false;

layout gridded;

layout datalattice columnvar = qstest/ ;
	layout prototype;
		barchart X=week y=mean / group=week barlabel=false orient=vertical name='a';
	endlayout;
endlayout;
layout lattice / columns = 1 rowweights = (.15 .25);

			blockplot x=qstest block=n12 /class = week repeatedvalues=true display=(values label outline) valuehalign=center label='Week 12' valueattrs=graphdata1 labelattrs=graphdata1;
			blockplot x=qstest block=n24 /class = week repeatedvalues=true display=(values label outline) valuehalign=center label='Week 24' valueattrs=graphdata2 labelattrs=graphdata2;
			blockplot x=qstest block=n36 /class = week repeatedvalues=true display=(values label outline) valuehalign=center label='Week 36' valueattrs=graphdata3 labelattrs=graphdata3;
			discretelegend 'a' / title='Week: ' across=3 border=false;
	endlayout;

endlayout;

endgraph;
end;

run;

Let me know if this makes any sense to you.

(It hardly does to me)

Good luck!

Are you using SAS 9.2 or SAS 9.3?

AncaTilea - the nXX variables are to summarize the number of subjects at a given timepoint. I did try your code - thanks for it - it comes close but not quite in terms of spacing/weighting, much like my own attempts. I did end up talking to SAS tech support directly and they indicated in order to really get what I wanted I needed to upgrade to 9.3 (a difficult proposition working in a clinical environment mid-study) so they provided an alternative of placing the subject counts within the graph itself using a scatterplot. This had its own drawbacks, but it was close to what was being asked for working under 9.2.

If you're stuck at 9.2, and need a non-SG-proc solution, here are a few traditional SAS/Graph charts where I annotate a "table" of data below the bars. Perhaps this will give you some ideas you can combine with what you learned from Tech Support...
