    public abstract class AbstractHistogramDataset
extends org.jfree.data.statistics.SimpleHistogramDataset
    Base class for histogram datasets to be used with JFreeCharts. This will accumulate values in a buffer until #update() is called. At that point the current histogram data will be removed and the data in the buffer will be histogramed. The default is never to fire change events and let the chart execute code do that actual update via the plot.
