title "Histogram with a Normal Curve Overlaid";
proc sgplot data = Learn.Blood;
histogram RBC;
density RBC;
run;
where should i add the type = kernel ?
where should i add the nbins= and binwith= ?
Hi @tianerhu,
TYPE= is an option of the DENSITY statement. NBINS= and BINWIDTH= are options of the HISTOGRAM statement.
Example 1:
proc sgplot data = sashelp.heart;
histogram systolic / nbins=25;
density systolic / type=kernel;
run;
Example 2:
proc sgplot data = sashelp.heart;
histogram systolic / binwidth=10;
density systolic / type=kernel(c=5 weight=quadratic);
run;
Of course, with type=kernel you would need to change the title.
