I though there would be an easy way, but I couldn't find it.
What I did find was another thread with something similar. I'm not terribly sure how the solution of that thread works, but one of the other posts worked.
Here is the thread: https://communities.sas.com/t5/SAS-Enterprise-Guide/Locating-titles-inside-of-chart-area-in-proc-sgp...
I used Bryan's solution:
I also switched from your table to SASHELP.CARS so I could test the solution.
Looks like you can use another table as a way to annotate your visual using the sganno option in the proc sgplot statement.
Something like this? You'd have to dive a bit more into the columns to create to set similar formatting to what you have:
Data anno;
function="text";
x1space= 'graphpercent';
y1space= 'graphpercent';
width=400;
textweight='bold';
textsize=10;
y1=95;
x1=50;
label="Location Quotient";
output;
run;
proc sgplot data=sashelp.cars NOAUTOLEGEND sganno=anno ;
title 'test';
styleattrs DATACOLORS=(cxEAAA00 cx002855);
hbar Make / response=MSRP
group=Origin
nooutline
barwidth=0.8;
xaxis DISPLAY=(NOLABEL)
VALUEATTRS=(Family=Calibri Size=8);
yaxis label="Location Quotient"
LABELATTRS=(Family=Calibri Size=8 Weight=Bold)
LABELPOS=TOP
discreteorder=data
type=discrete fitpolicy=none
VALUEATTRS=(Family=Calibri Size=8);
run;
