CHistogram:Class Description

The CHistogram class is used to compute the frequency distribution, or "histogram", of an array of values. This class provides methods for choosing the binning strategy and for computing the histogram.

Usage

Construction	Object = CHistogram:new()
Destruction	Object:delete()

Class Properties

This class has no properties.

Class Methods

Construction

new	Creates a new instance of a CHistogram object.
delete	Deletes the instance of the CHistogram object.

Operations

Calc	Calculates the histogram using current binning parameters.
SetBinWidth	Configures the histogram to prioritize the bin width.
SetBinCount	Configures the histogram to prioritize the number of bins.
SetBinAuto	Sets the binning to automatically compute binning parameters. This is the default.
SetCorrelated	Allows faster computation when the data are correlated rather than randomly ordered.

Auto Binning Methods

These methods return the actual binning values that were used for auto binning mode.

GetBinCount	Returns the bin count that was used.
GetBinWidth	Returns the bin width that was used.
GetMin	Returns the minimum value used
GetMax	Returns the maximum value used.
