first of course data not continous, randomly sampled. see graph:
as can see have data sampled in not known interval.
/** * represents sample graph above. stored in arraylist */ public class sample { public long time; public long value; } from these samples need compute averages @ given sampling frequency. problem not entirely sure how calculate average values - must influenced points near sampling time, increasing distance must reduce influence.
i don't know search, lack vocabulary on topic.
