How to set the circle size same proportion of the number of peaks when there are more than 2 sets using `makeVennDiagram`? about chippeakanno HOT 5 CLOSED

I bet it rather challenging to make proportional Venn Diagrams with more than 2 sets. It is mathematically not possible in my mind.

@hukai916 How about if we can use ovals instead of only round circles? Thanks

Hi @danli349 ,
Thank you for your question. Just above the section Generate_annotation_data, there is documentation to plot the Venn by Vennerable package. I copied the doc here:

Alternatively, users have the option to use other tools to plot Venn diagram. The following code demonstrates how to use a third party R package Vernerable with the output from the function findOverlapsOfPeaks.

#     install.packages("Vennerable", repos="http://R-Forge.R-project.org",
#                     type="source")
#     library(Vennerable)
#     venn_cnt2venn <- function(venn_cnt){
#         n <- which(colnames(venn_cnt)=="Counts") - 1
#         SetNames=colnames(venn_cnt)[1:n]
#         Weight=venn_cnt[,"Counts"]
#         names(Weight) <- apply(venn_cnt[,1:n], 1, base::paste, collapse="")
#         Venn(SetNames=SetNames, Weight=Weight)
#     }
#
#     v <- venn_cnt2venn(ol$venn_cnt)
#     plot(v)

It is possible with ovals @danli349, this R package can do that: https://cran.r-project.org/web/packages/eulerr/vignettes/introduction.html

Just follow @jianhong's documentation and draw with your favorable third-party plotting tools.

@hukai916 @jianhong That is awesome. Thanks a lot.
