I want to show overlap between lists of genes using a venn diagram. HOWEVER, I don't want a program that will subtract the number of genes from my set if they show overlap. Let me give an example, lets say you have two lists like this:

list1 = a, b c, d

list2= b, c, d, f

Almost all the popular venn diagram programs such as venny, Venn from http://bioinformatics.psb.ugent.be/webtools/Venn/, and the VennDiagram function from limma will "subtract" the number of data you have in each set and display something like this:

list1                         list2

(1)            (3)            (1)

I don't know how to share photos on stackexchange, it won't let me import them from my computer and I don't have a flickr or some other way of linking pics.

Basically most of these programs will subtract the amount of items you have from your list and move them to the intersection instead of keeping the number of items you have in a single list. So Ideally I want a venn diagram that displays 4 on the list 1 and list 2 section of the venn diagram and simply shows me how many terms are similar in overlaps. Something like this:

list1                         list2

(4)            (3)            (4)

Is there a good way to do this? My R knowledge is lacking and if I had to I could just live with being able to generate # of overlaps between multiple sets so I can draw them myself in a venn diagram. Thanks for the help
