HI all
I know you can add a refline in PROC SGPLOT but can you do it in PROC SGSCATTER?
e.g. This is the code we would use to get a refline at Y=0 using PROC SGPLOT but we are teaching a course that primarily uses SGSCATTER as has the ability to produce multiple scatterplots in one PROC and keen to just stick with that.
PROC SGPLOT DATA=dataset;
SCATTER X= xvar Y= yvar;
LOESS X= xvar Y= yvar;
REFLINE 0;
RUN;
Thank you Marisa

Sgcatter does have tmplout on the PROC statement so you can get the GTL code and modify that.
Or switch to SGPANEL?

Thank you Reeza
Yes we can add a LOESS line in PROC SGSCATTER but are looking for a ref line at Y = 0.
We currently use a mix of PROC GPLOT and PROC SGSCATTER but are hoping to just use one and not introduce another to be consistent with out other units.

Could also be done with SG annotation.

Thank you PG
We are keen to keep with PROC SGSCATTER as that is what is used throughout our course.

SGSCATTER is not a good choice as a general purpose graphing procedure, if I may say so. Here is how to draw reference lines with annotation in SGSCATTER:
data reflines;
retain drawspace "layoutpercent" linecolor "blue";
input function $ x1 y1 x2 y2;
datalines;
line 11 55.5 53.5 55.5
line 56 55.5 99 55.5
;
proc sgscatter data=sashelp.class sganno=reflines;
compare x=(age height) y=weight / loess=(degree=2);
run;
Positioning the reference lines was by trial and error as you cannot tie their positions to data values.
