We're really deleting data. There are different culling strategies, and you can implement your own. But the strategy we're using is in MinGapDataCuller.java. Let the maximum size be N. Then: 1. Let the chart grow to N in size. 2. Until the chart is N/2+1 in size, repeat: 2A. Remove the point whose left and right neighbors are closest to one another. Break ties by choosing the earlier point. Never remove the first and last points in the series.
