I'm using PROC REG in SAS 9.4 with the default ODS Graphics. What's the easiest way to add a reference line to the fit plot?
1. If you only need to do this one time, use the ODS Graphics Editor to add the reference line.
2. If you have only one explanatory variable, you can use the REG statement in SGPLOT and bypass the REG procedure altogether:
proc sgplot data=sashelp.class;
reg y=weight x=height;
refline 100 / axis=y;
run;
3. If you need to do this every time you run the analysis, then use the ODS OUTPUT statement to save the data to a SAS data set, and then use PROC SGPLOT to reconstruct the graph. You can use the REFLINE statement to add reference lines.
