org.autoplot.aggregator.AggregatingDataSource

Data Source that aggregates (or combines) the data from granule files containing data for intervals. For example, https://cdaweb.gsfc.nasa.gov/istp_public/data/polar/hydra/hyd_h0/$Y/po_h0_hyd_$Y$m$d_v$v.cdf?ELECTRON_DIFFERENTIAL_ENERGY_FLUX&timerange=20000109 is the aggregation of daily files from the CDAWeb. This provides an easy method for storing a long time series without having a complex data server. The result of this is not guaranteed to be monotonically increasing in time. See https://sourceforge.net/p/autoplot/bugs/1326/
