Both superscript and supscript are not working in proc sgplot

[Andrea_Peng]

I am trying to get some special character in the graph but failed. Both superscript and supscript are not working.

My code is:

ods rtf file="C:\work\test.rtf";
goptions reset=all;
ods escapechar="^";
ods graphics on / attrpriority=none noborder;
PROC SGPLOT DATA = Srp2;
format tp tpa.;
styleattrs datacontrastcolors=(grey) datasymbols=(circlefilled trianglefilled circle) datalinepatterns=(solid longdash dot);

SERIES X = tp Y = mean/ group=surg_grp name="Surgical Method" lineattrs=(thickness=2) MARKERS markerattrs=(size=8 color=black);
XAXIS label="Time" TYPE = DISCRETE ;
YAXIS LABEL = "SR^{sub P} (2 Chamber) (s^{super -1})" VALUES = (0 TO 10 BY 1);
TITLE "SR^{sub P} (2 Chamber) Trend by Surgical Method";
keylegend "Surgical Method";
RUN; 
ods graphics off;
ods rtf close;

The graph is:

I did find some discussion about this but looks like it did not really solved!

Anyone have any suggestion?

Thanks!

Using an annotation data set might work.  In the program below, I used the SASHELP.CLASS data set.  

ods rtf 
    file='/folders/myfolders/ODS Graphics/subscripts_and_superscripts_via_annotations_PROC_SGPLOT.rtf'
    style=HTMLBlue; 
ods pdf file='/folders/myfolders/ODS Graphics/subscripts_and_superscripts_via_annotations_PROC_SGPLOT.pdf'; 


ods escapechar="^";
ods graphics on / attrpriority=none noborder;

* you can use data step coding to set up the annotations, but it can get complicated
* quickly. ;

data anno;
 infile datalines dlm='#';
 length function $ 8 label $ 50 drawspace $ 12 textweight $ 4 justify $ 6;
 input function $ drawspace $ rotate width textweight $ justify $ x1 y1 discreteoffset label $;
 datalines;         
 text # graphpercent # 90 # 50 # bold # center # 2 # 50 # -0.5 # SR^{sub 'P'} (2 Chamber) (s^{sup '-1'})
 text # graphpercent # 0 # 50 # bold # center # 50 # 98 # -0.5 # SR^{sub 'P'} (2 Chamber) Trend by Surgical Method
    ; 
run;

* used the pad option on PROC SGPLOT to create room for the annotations.  
* otherwise, they may end up jammed too close to the plot. ;

proc sgplot data=sashelp.class pad=(left=20 top=20) sganno=anno;
	scatter x=weight y=height;
	yaxis display=(nolabel);
run;

* SAS provides a bunch of macros to do annotation, which is the easier way! ;

%sganno;

%let yaxislabel=SR(*ESC*){sub 'P'} (2 Chamber) (s(*ESC*){sup '-1'});

%let titlelabel=SR^{sub 'P'} (2 Chamber) Trend by Surgical Method;

data anno_via_macros;
  %sgtext(drawspace="wallpercent", x1=-20, y1=40, width=70, rotate=0, 
          textweight="bold", justify="center",
          label="&yaxislabel");
  %sgtext(drawspace="wallpercent", x1=50, y1=105, width=70, rotate=0,
          textweight="bold", justify="center",
          label="&titlelabel");
run;

proc sgplot data=sashelp.class pad=(left=30pct top=10pct) sganno=anno_via_macros;
	scatter x=weight y=height;
	yaxis display=(nolabel);
run;

ods rtf close;
ods pdf close;

The y axis label text looks fine in the Results Viewer, but when I opened the RTF, the term involving the negative exponent was jumbled.  When I opened the PDF, there was a gap between the s and the negative exponent.

I tried adding some extra space to the left side of the graphic, so that the annotation for the y axis would fit if I didn't rotate it.  The term involving the negative exponent looks as expected in the RTF output.  

I found Dan Heath's paper Annotating the ODS Graphics Way! helpful in figuring this out.

Thanks, Suzanne! Create the data annon is working! I will have a look at Dan Heath's paper!
