proc sgplot data = Learn.Blood;

    histogram RBC;

    density RBC;

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.
