Adding percentiles as references lines

[dustychair]

Hi, 

Is there any way to add percentiles ( maybe only the first, second and third percentiles) as vertical reference lines on the density normal plot?

thanks

Here's one way to do it:

proc means data=sashelp.heart P25 P50 P75;
var cholesterol;
ods output summary=pctls;
run;

data merged;
set sashelp.heart pctls;
run;

proc sgplot data=merged;
density cholesterol;
refline Cholesterol_P25 / axis=x legendlabel="25th" lineattrs=(color=blue thickness=3) name="p25";
refline Cholesterol_P50 / axis=x legendlabel="50th" lineattrs=(color=red thickness=3) name="p50";
refline Cholesterol_P75 / axis=x legendlabel="75th" lineattrs=(color=green thickness=3) name="p75";
keylegend "p25" "p50" "p75" / title="Percentiles";
run;

Hope this helps!
