Hi @tianerhu,

 

TYPE= is an option of the DENSITY statementNBINS= 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.
