Need subscript in y-axis title

tarheel13 — Thu, 17 Nov 2022 20:13:53 GMT

Hi, I'm outputting a figure from proc sgplot to RTF with ODS. I need to get some subscripts in my y-axis titles since it's PK parameters. Here's an example of what I tried.

proc format;
	value trtf
	2='0.25 mg/kg'
	3='0.75 mg/kg'
	4='1.50 mg/kg'
	5='3.0 mg/kg'
	6='6.0 mg/kg'
	7='12.0 mg/kg'
	8='24.0 mg/kg'
	9='48.0 mg/kg'
	;

	value paramf
	1="AUC&esc.{sub 0-inf} (h*ng/mL)"
	2="AUC&esc.{sub 0-24} (h*ng/mL)"
	3="AUC&esc.{sub 0-t} (h*ng/mL)"
	6="C&esc.{sub max} (ng/mL)"
	14="T&esc.{sub max} (h)"
	;
run;

&esc is a macro variable for escape character. This is the way I know to get subscript but it's not coming out right in output.

Have you tried it with the actual escape character to see if the macro facility is not resolving the macro variable? I have only used unicode characters in formats with the format statement in open code like this: (*ESC*){unicode '2013'x}

I have read on here that axis titles don't support sub and sup commands. I got 0 and - to subscript but I can't get the lowercase t.

This thread suggests it can work if you find the right unicode text.

came across that thread today as well but today I was just informed that I don't need to do the subscript.

Thanks. can try next week. I have to do different labels for each PK parameter though. Would I need a different _anno dataset then for each PK parameter?

I don't understand what you mean.
Post a picture to explain .

I have to make different vertical box plots for each PK parameter. The labels should be what I posted in paramf. So the y-axis label needs to be whatever the respective PK parameter is.

You want this ?

data have;
set sashelp.heart;
if bp_status='High' then paramf=1;
if bp_status='Normal' then paramf=2;
if bp_status='Optimal' then paramf=3;
run;



data _anno;
length label $ 200;
 x1space="datavalue"; y1space="layoutpercent";function="text";
textweight="normal"; textsize=12;textcolor="black"; width=200;
 x1=1; y1=2.5;label="AUC(*ESC*){sub '0-inf'} (h*ng/mL)"; output;
 x1=2;y1=2.5;label="AUC(*ESC*){sub '0-24'} (h*ng/mL)"; output;
 x1=3;y1=2.5;label="AUC(*ESC*){sub '0-t'} (h*ng/mL)"; output;

 run;

title ;
proc sgplot data=have  sganno=_anno noautolegend;   
vbox weight/category=paramf;
xaxis label=' ' display=(novalues);
yaxis label=' ';
run;

it is closer to what I am looking for but I need to use avalc as well. I am supposed to do vertical box plots of PK parameters by timepoint and ADA status (positive or negative). Each timepoint should be on a separate page. I'll take care of that with the by statement in sgplot. Y-axis label should be "PK Parameter (unit)".

Post your real data and a picture you want to see.
It is hard to understand what you want by your words.

I have to work off of a shell and there is no picture. I have already posted what was in the shell.
