PROC SGPLOT: how to add a dynamic footnote/text?

[somebody]

How can I add a text or footnote that takes the value of a variable? So it changes  depending on the BY group

[PeterClemmensen]

Why not let SAS do that by itself?

proc sgplot data=sashelp.iris;
	scatter x=sepallength y=sepalwidth;
	by species;
run;

Result

If the BY statement default text (as shown by @PeterClemmensen) are not exactly what you want, you can add the BY variable name and/or BY variable value into the TITLE or FOOTNOTE statement text, as described here:

which applies to all SAS procedures, not just PROC SGPLOT.
