I have a dataset which contains a list of IDs, each of which belongs to at least a target (let's name them TGT1, ... TGTN). I can present this dataset in two ways, e.g.:
A) as a list
where ID 100 belongs to targets 1 and 4, 101 only to target 1, 102 to targets 2 and 3, and so on.
B) as a matrix
TGT_name TGT1 TGT2 TGT3 TGT4
TGT1 2 0 0 1
TGT2 0 1 1 0
TGT3 0 1 1 0
TGT4 1 0 0 1
where on the diagonal there is the frequency of distinct IDs in each single target, and on the non-diagonal elements (i,j) there is the frequency of the overlapping IDs in targets i and j.
Now, I would like to present graphically the overlapping situation among targets, to immediately identify which targets overlap most, instead of looking at the matrix data.
Which kind of graph would you recommend me? I didn't find a kind of graph which suits this dataset, maybe should I rearrange it in a different way? I'm using mostly Enterprise Guide, but I can write a macro as well if needed.
Thank you very much!
