Pie Charts with subgroups

[Anita_n]

Dear all, 

suppose I have a dataset that looks like this, and I wish to create a pie chart with sub categories  as shown below

proc format;
value $ level "1"="level1"
             "2"="level2"
			 "3"="level3"
			 "5"="level5"
			 "6"="level6"
			 "7"="level7"
;
run;


data have;
	infile datalines;
	format level $level.;
	input answers $4. level $2.  num_of_subjects  ;
	datalines;
No  1 100
yes 1 50
No  2 80
yes 2 150
yes 3 16
No  3  2
yes 5  45
No  6  180
yes 6  200
No  7   55
;
run;

legend1 label=none
        shape=bar(4,1.5)
        position=(top left)
        offset=(5,)
        across=2
        mode=share;

proc gchart data=have ;
    pie level / detail=answers
	            other=0
				midpoints= 'level1' 'level1' 'level2' 'level2' 'level3' 'level3' 'level5' 'level6' 'level6' 'level7' 
                radius=35
                angle=90
                slice= none
				noheading
                coutline=black
				legend=legend1;
		
run;
quit;

how do I include the variable num_of_subjects in the code to get the exact proportion of each slices. I also wish to include the value of num_of_subjects in each subgroup/slice. Using SUMVAR sums up the variables and that is not what I want.

Thanks for any help

Don't you want to sum the number of subjects?

Thanks, I realised I actually need to use SUMVAR. So I finally got it working, thanks
