public static interface Histogram.BinScheme
An algorithm for determining the bin in which a value is to be placed as well as calculating the upper end of each bin.

  • Method Summary

    Modifier and Type Method Description
    int bins()
    Get the number of bins.
    double fromBin​(int bin)
    Determine the value at the upper range of the specified bin.
    int toBin​(double value)
    Determine the 0-based bin number in which the supplied value should be placed.

  • Method Details

    • bins

      int bins()
      Get the number of bins.
      Returns:
      the number of bins

    • toBin

      int toBin​(double value)
      Determine the 0-based bin number in which the supplied value should be placed.
      Parameters:
      value - the value
      Returns:
      the 0-based index of the bin

    • fromBin

      double fromBin​(int bin)
      Determine the value at the upper range of the specified bin.
      Parameters:
      bin - the 0-based bin number
      Returns:
      the value at the upper end of the bin; or negative infinity if the bin number is negative or positive infinity if the 0-based bin number is greater than or equal to the number of bins.
