How to modify or shrink the size of a plot inside the frame? The label "subject" is overlapped with first patient id. 

Thanks a lot! 

Here are part of my code. 

Data anno2;
length label $200 x1space $20 y1space $20 ;
retain function "text" anchor "left";
x1space="Graphpercent";
x1=5;
y1space="Graphpercent";
y1=96.5;
width=200;
label="Subject(*)";
id="xxxx";
run;

data anno2_;
set swimmer;
keep item subjid;
run;

data anno2_;
set anno2_;
length label $200 x1space $20 y1space $20 ;
retain function "text" anchor "left";
x1space="Graphpercent";
x1=5;
y1space="DATAVALUE";
y1=item;
width=0;
label=strip(subjid);
id="xxxx";
run;

data anno2;
set anno2 anno2_;
run;

ods listing close;

options nodate nonumber;
ods &filetype file = "&output.\&outname..&filetype" style = styles.&rpttype. nogfootnote nogtitle startpage = yes bookmark="&outname";
