case class Histogram(height: Double, bins: Array[HistogramBin]) extends Product with Serializable
This class is an implementation of equi-height histogram. Equi-height histogram represents the distribution of a column's values by a sequence of bins. Each bin has a value range and contains approximately the same number of rows.
- height
number of rows in each bin
