Just some ideas: I'd start with a step that searches your data for any continuous blocks 'above the threshold'. Afterwards you could copy any of the found blocks ouit of the original data. This leaves memory allocation at an minimum. The first step can be done in a FOR loop with some shift registers. One could hold an arry of (cluster of (startIdx, endIdx)) (initialezed with an empty array), another one a boolean 'above?' (initialized with False). Check for every data point if it is above and if 'above?' changed from the last iteration. If so, set the apropriate Idx in the last array element and, if 'above?' switched to True, append a new array element before. When your FOR finishes you may just feed that array with autoindexing into another For and feed the original data without autoindexing. Now you can catch any subarrays starting at startIdx with a length of (endIdx-startIdx). I did not really get your display reqs, so you have to deside if and how you append those data for displaying purposes. Just my �0.02!
