SGPLOT vbar option not working ?

morglum — Thu, 12 Nov 2015 21:44:38 GMT

I have a dataset with aggregated date and I would like to create a VBAR to show the distribution of the variables. I thought using the weight option would work, but it doesnt. For example, in the example below all the frequencies stand at "1", instead of using the count variable which should be somewhere between 1 and 5.

What is going on? I'm using SAS 9.3 on a windows machine.

Cheers!

proc sql;
create table class as
select distinct age, count(*) as count
from sashelp.class
group by age;
quit;

proc sgplot data=class;
vbar age / weight=count;
run;

Use response instead of weight.

proc sgplot data=class;
vbar age / response=count;
run;

You can also use FREQ= instead of WEIGHT= if you prefer "Frequency" over "count (Sum)" as the label of the y-axis.

proc sgplot data=class;
vbar age / freq=count;
run;

Thanks for the reply!

"Frequency" does look better, but it wont graph non-integer numbers properly (such as count minus 0.5), which happens with surveys with probabilistic weights.

Cheers!

proc sql;
create table class as
select distinct age, count(*)-0.5 as count
from sashelp.class
group by age;
quit;

proc sgplot data=class;
vbar age / response=count;
yaxis label="frequency";
run;

proc sgplot data=class;
vbar age / freq=count ;
yaxis label="frequency";
run;
