In reply to Ksharp.

Need a combined effectplot chart.

proc glm data=dataset4 ;
model SAD = wM PW_M PD_M CogS_M wMCogS wM | PW_m wMPD AGE MALE ;
weight W1C0;
store contcont;
run;
quit;
proc plm restore =contcont;
effectplot fit(X=PW_m plotby=wM=-1 0 1 ) /clm;
run;

I get 3 charts.
can I put this in one chart and do it for wM by PW_m
