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;
Thank you Marisa
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.
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.
