I wrote something about it in a thread some weeks ago:  
http://lists.puredata.info/pipermail/pd-list/2013-05/102819.html

ah, you mean an "element" instead of a scalar (although they're all  
scalars when drawn). the only way I would remember now would be use the  
[struct] output to trigger a comparation of the previous array with the  
current one, saved as lists. not optimal at all, but it can work if there  
aren't too many elements.
