4-way venn diagram

SAS--_lover — Sun, 03 Jun 2018 01:03:02 GMT

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 ballardw available at https://communities.sas.com/t5/SAS-GRAPH-and-ODS-Graphics/3-way-Venn-diagram/td-p/248018 but still couldn't make it.

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

0111	74	0.60
1111	431	3.47
0000	9122	73.46
;

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="",

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

Thank you for your time, PGStats. I just removed the percentages (the frequency is enough) in case that simplifies the effort to get a venn diagram. Otherwise, I will use your suggestion.
