## 4-way venn diagram

Hello!

I need to plot a 4-way venn diagram in SAS 9.4 using the attached data. The counts that go into the 16 groups/regions of the diagram are as follows. I spent several hours trying to modify the 3-way venn diagram macro by

I was wondering if someone could help me?

Thank you.

 ABCD Frequency Region description 1000 475 A 0100 686 B 0010 139 C 0001 119 D 1100 206 Intersection of A and B 1010 115 Intersection of A and C 1001 106 Intersection of A and D 0110 117 Intersection of B and C 0101 68 Intersection of B and D 0011 49 Intersection of C and D 1110 383 Intersection of A, B and C 1101 152 Intersection of A, B and D 1011 175 Intersection of A, C and D 0111 74 Intersection of B, C and D 1111 431 Intersection of A, B, C and D 0000 9122 Outside the venn diagram

That is quite a challenge! Just in case you want to switch to something simpler, here is an alternative

``````proc format;
value A 0 = "a" 1 = "A";
value B 0 = "b" 1 = "B";
value C 0 = "c" 1 = "C";
value myD 0 = "d" 1 = "D";
run;

data freq;
input (A B C D) (1.) Freq Perc;
format a a. b b. c c. d myd.;
datalines;
1000	475	3.83
0100	686	5.52
0010	139	1.12
0001	119	0.96
1100	206	1.66
1010	115	0.93
1001	106	0.85
0110	117	0.94
0101	68	0.55
0011	49	0.39
1110	383	3.08

0111	74	0.60

;

proc tabulate data=freq order=formatted;
class a b c d;
var freq perc;
label freq = "Frequency" perc = "Percent";
table
freq*format=5.0 perc*format=5.2,
a=""*b="",
c=""*d=""*mean="";
run;``````

(note: it would actually look decent in ODS RTF or PDF)
