Following the hint of Penguin_Knight, you can try to draw it in
You did not specify what the intersection among A,B and C was, so I am assuming here to be zero.
venn.plot = draw.triple.venn(
area1 = 1000,
area2 = 3000,
area3 = 5000,
n12 = 200,
n23 = 120,
n13 = 0,
n123 = 0,
category = c("A", "B", "C"),
fill = c("green", "red", "darkblue"),
scaled=TRUE, ind = FALSE,
Unfortunately, it seems the
scaled argument is not working in the VennDiagram package.
So, if by "precisely" you mean: areas proportional in size to the count values, here is another option, using the
See more info here on the package and here to download it.
Venn_object = Venn(list(A = 1:1000,B = 801:3800, C = 3681:8680))
plot(Venn_object, doWeights = TRUE)
I could not find how to rotate the chart (horizontal position).
