com.metsci.glimpse.core.painter.plot.HistogramPainter

All Implemented Interfaces:

GlimpsePainter

public class HistogramPainter
extends GlimpsePainterBase

Plots a simple frequency histogram. Binning of data is handled automatically. Construct with asDensity = true to scale as a density estimate instead of as a frequency histogram.
