proc gplot: add existing attribute as text box to graph

[SarahDew]

When making a graph through gplot, is there a way to add extra information as text to your graph, but the info is predefined and should be gathered from your data.

I now do the following, and would like for the first graph to have a text box somewhere (preferably top right corner) with "flag = 0" and with "flag = 1" for the last two graphs.

data digits;
input ID $1. digit observed expected;
datalines;
A 1 33.3 33.3
A 2 33.3 33.3
A 3 33.3 33.3
B 1 25 33.3
B 2 75 33.3
B 3 0 33.3
C 1 45 33.3
C 2 45 33.3
C 3 10 33.3
;run;

data attribute;
input ID $1. flag;
datalines;
A 0
B 1
C 1
;

proc gplot data=digits;
plot expected*digit
observed*digit
/ overlay legend vref=0 ;
by ID;
run;

In PROC GPLOT, you would need to use the ANNOTATE facility to add text or a box to a graph

See: https://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.4&docsetId=graphref&docsetTarget=p1b...

You might be better off using PROC SGPLOT to do your plotting (it's a newer procedure with lots of nice features), in which case you can add text more easily using the INSET or TEXT statements.
