Interface IHistogram1D

All Superinterfaces:

IHistogram, Serializable

All Known Implementing Classes:

hep.aida.ref.AbstractHistogram1D, Histogram1D

public interface IHistogram1D

extends IHistogram

A Java interface corresponding to the AIDA 1D Histogram.

Note All methods that accept a bin number as an argument will also accept the constants OVERFLOW or UNDERFLOW as the argument, and as a result give the contents of the resulting OVERFLOW or UNDERFLOW bin.

Method Detail

binEntries

public int binEntries(int index)

Number of entries in the corresponding bin (ie the number of times fill was called for this bin).

Parameters:

index - the bin number (0...N-1) or OVERFLOW or UNDERFLOW.

binError

public double binError(int index)

The error on this bin.

Parameters:

index - the bin number (0...N-1) or OVERFLOW or UNDERFLOW.

binHeight

public double binHeight(int index)

Total height of the corresponding bin (ie the sum of the weights in this bin).

Parameters:

index - the bin number (0...N-1) or OVERFLOW or UNDERFLOW.

fill

public void fill(double x)

Fill histogram with weight 1.

fill

public void fill(double x,
                 double weight)

Fill histogram with specified weight.

mean

public double mean()

Returns the mean of the whole histogram as calculated on filling-time.

minMaxBins

public int[] minMaxBins()

Indexes of the in-range bins containing the smallest and largest binHeight(), respectively.

Returns:

{minBin,maxBin}.

rms

public double rms()

Returns the rms of the whole histogram as calculated on filling-time.

xAxis

public IAxis xAxis()

Returns the X Axis.
