Hi Folks,
I've created a scatter plot in SGPLOT with the GROUP= option and overlaid it with a regression also with the GROUP= option. Because of the density of the data points in the scatter plot, I want to specify a contrasting colors for the regression lines that are different from the scatter plot marker colors and thus improves readability but I cannot find a way to do this, even with an ATTRID= specification. Adjusting the transparency of the markers for the scatter plot does not help. The overlaid regression lines cannot be the same color. Many thanks for all suggestions. Code below, example attached.
data attrmap;
set &library..tablvars_labs_evnts_phz&phz.(keep=CIRRHOSIS);
if CIRRHOSIS='Y' then linecolor='Blue';
else if CIRRHOSIS='N' then linecolor='Red';
id='myid';
run;
proc sort data=&library..tablvars_labs_evnts_phz&phz.; by TESTCD CIRRHOSIS EOTWKS; run;
proc sgplot data=&library..tablvars_labs_evnts_phz&phz. noautolegend;
by TESTCD;
where BINSVR='SVR' and TESTCD in ('PLAT');
