It is easier to help if you provide more information. If you want to get histograms of two variables, you can do that using SGPLOT procedure with two variables like below. You can add Normal and Kernel density plots, or customize the plot as you want.

title 'Distribution of Blood Pressure';

proc sgplot data=sashelp.heart;

histogram systolic / transparency=0.5 binwidth=5;

histogram diastolic / transparency=0.5 binwidth=5;

keylegend / location=inside position=topright across=1;

xaxis display=(nolabel);

run;

Something like this:

proc sgplot data=sashelp.heart;

histogram systolic / transparency=0.5 binwidth=5 ;

density systolic / type=kernel (c = 0.75);

histogram diastolic / transparency=0.5 binwidth=5;

keylegend / location=inside position=topright across=1;

xaxis display=(nolabel);

run;

Good luck!
