Best kind of graph to present overlapping target frequency

Hi everybody,

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

ID TGT

100 1

100 4

101 1

102 2

102 3

...

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!

Regards

You could use a heat map as discussed in this article.

Or a grid like shown in this article. You can modify these to include the diagonals.
