Further, for each collection containing one or more intervals, the method includes determining one or more statistical parameters characterizing a distribution of the data within the collection. Still further, for each collection, the method includes applying one of a plurality of different histogram-producing algorithms based on the one or more statistical parameters to produce a histogram such that at least two of the different histogram-producing algorithms are used to render a respective different portion of the histogram.
