How to create a histogram with median as a middle point

HappySASUE — Tue, 28 May 2019 12:57:52 GMT

Is it possible to create a histgram with only 2 uneven bins: ">= median" and "< median" ? Using either proc univariate, or sgplot. How to set the middle or endpoint? Thanks

What do you mean by endpoints? If I understand you correctly, you can do something like this

proc sql;
   create table temp as
   select *, 
   median(height),
   (case
      when height lt median(height) then "< median"
      when height ge median(height) then ">= median"
     end) as overunder
   from sashelp.class;
quit;

proc sgplot data=temp;
   vbar overunder;
run;

Sure, that's just a bar chart though, I wouldn't call it a histogram. And in theory, it should be a straight line because that's the definition of the median.
