Public Methods

Method	Description
Add ( Histogram histogram ) : Histogram	Adds one histogram from the other, storing results in a new histogram, without changing the current instance.
Add ( int histogram ) : Histogram	Adds one histogram from the other, storing results in a new histogram, without changing the current instance.
Clone ( ) : object	Creates a new object that is a copy of the current instance.
Compute ( double values ) : void	Computes (populates) an Histogram mapping with values from a sample.
Compute ( double values, double binWidth ) : void	Computes (populates) an Histogram mapping with values from a sample.
Compute ( double values, int numberOfBins ) : void	Computes (populates) an Histogram mapping with values from a sample.
Compute ( double values, int numberOfBins, bool extraUpperBin ) : void	Computes (populates) an Histogram mapping with values from a sample.
Compute ( double values, int numberOfBins, double binWidth ) : void	Computes (populates) an Histogram mapping with values from a sample.
FromData ( double values ) : Histogram	Creates a histogram of values from a sample.
GetRange ( double percent ) : IntRange	Get range around median containing specified percentage of values. The method calculates range of stochastic variable, which summary probability comprises the specified percentage of histogram's hits. Sample usage: `// create histogram Histogram histogram = new Histogram( new int[10] { 0, 0, 1, 3, 6, 8, 11, 0, 0, 0 } ); // get 50% range IntRange range = histogram.GetRange( 0.5 ); // show the range ([4, 6]) Console.WriteLine( "50% range = [" + range.Min + ", " + range.Max + "]" );`
Histogram ( ) : System	Constructs an empty histogram
Histogram ( int values ) : System	Constructs an empty histogram
Multiply ( int histogram ) : Histogram	Multiplies one histogram from the other, storing results in a new histogram, without changing the current instance.
NumberOfBins ( double values, DoubleRange range, BinAdjustmentRule rule ) : int	Computes the optimum number of bins based on a BinAdjustmentRule.
Subtract ( Histogram histogram ) : Histogram	Subtracts one histogram from the other, storing results in a new histogram, without changing the current instance.
Subtract ( int histogram ) : Histogram	Subtracts one histogram from the other, storing results in a new histogram, without changing the current instance.
ToArray ( ) : int[]	Converts this histogram into an integer array representation.
Update ( ) : void	Update statistical value of the histogram. The method recalculates statistical values of the histogram, like mean, standard deviation, etc., in the case if histogram's values were changed directly. The method should be called only in the case if histogram's values were retrieved through Values property and updated after that.
this ( int index ) : int	Gets the Bin values of this Histogram.
