Hello!
I have a spreadsheet. 17 respondents answered on the question, where should be selected 3 variants of there preferences.
I need to draw Pie graph to see % of variants 1-12 in columns (q22a-q22c)
Respondent Q22a Q22b Q22c
1 8 9 12
2 8 9 12
3 3 6 8
4 7 9 12
5 1 3 8
6 5 7 12
7 3 11 12
8 1 6 11
9 1 6 12
10 2 7 8
11 1 6 12
12 5 11 12
13 1 2 5
14 1 11 12
15 1 3 9
16 1 4 7
17 1 9 10
I tried to do:

tabulate Q22a , generate(a)
tabulate Q22b , generate(b)
tabulate Q22c , generate(c)
gen t1=c1+b1+a1
gen t2=c2+b2+a2
gen t3=c3+b3+a3
gen t4=c4+b4+a4
gen t5=c5+b5+a5
gen t6=c6+b6+a6
gen t7=c7+b7+a7
gen t8=c8+b8+a8
gen t9=c9+b9+a9
gen t10=c10+b10+a10
graph pie t1-t10

but tabulate can show only 10 rows but i have 12 rows, so it calcualted wrong, and it show me wrong labels after tabulate (like a1 ≠b1≠c1 ) (i manually created label for q22a-q22c (they are same) )
