how to do annotation in proc sgplot

VRD — Tue, 08 Apr 2014 08:42:54 GMT

I am using proc sgplot to get mean and SE plot.

I need to annotate so that i want to know number of subjects for each visit. this should be coming below the X-axis.

I wrote a paper a while back called "Now You Can Annotate Your Statistical Graphics Procedure Graphs" (http://support.sas.com/resources/papers/proceedings11/277-2011.pdf) that contains examples for creating output similar to your needs. The SG procedure annotation facility requires at least SAS 9.3. Let me know if you can't find an example that works for you, or if you have an questions.

This excellent blog gives you examples on pretty much everything 9.3/9.4 SGPLOT/GTL.

You may not need the "SG annotate facility" to achieve something as simple as a table of Ns. I have done this with BLOCKPLOT statement and there is a new XAXISTABLE statement that seems even better but I have not used that.

Look at the examples in the blogs before you do anything too drastic.

Hi,

I didnt get the type of graph i find. i created a program like below but not bale to assemble the Number of subjects properly.

data anno(drop=n visit_1);

set numb;

function='text';

x1space='datavalue';

y1space='graphpercent';

label=put(n,3.);

anchor='center';

x1=_n_;

y1=input(visit_1,3.);

run;

proc sgplot data=test2 noautolegend sganno=anno pad=(bottom=12%);

highlow x=visit_1 high=high low=low / highcap=serif lowcap=serif highlabel=label;

scatter x=visit_1 y=mean / group=visit_1 groupdisplay=cluster;

refline 10/axis=X;

Yaxis values=(0 to 18 by 2) label="Dose";

Xaxis label="Number shown in the graph is Number of Subjects in that Particular Visit";

run;

XAXIS table is available for 9.4. I am using 9.3 version

include the data with your program so we can see what it does.

test2 dataset -----visit_1, mean, high ,low, label are the variables with any values

num dataset ---- visit_1 number of subjects

test2 dataset

visit_1	mean	high	low
1	2	12	0
2	3	12	7
3	4	13	5
4	5	13	2
5	1	13	1
6	6	154	1
7	2	12	3
8	3	11	5
9	4	16	6
10	5	13	7

numb dataset

visit_1	number of subjects
1	2
2	3
3	4
4	5
5	1
6	6
7	2
8	3
9	4
10	5

with my code above i was trying to display number of subjects below the X-axis
