Detailed Description

Class for histogram with equal distribution step creation and maintenance.

Member Enumeration Documentation

enum ZHistogram::ZHistMode

Mode of numbers gathering

Enumerator
Absolute	build histogram by absolute values
Signed	build histogram by natural values

Constructor & Destructor Documentation

ZHistogram::ZHistogram	(	ZHistMode	hm,
		unsigned	nRanges = `100`
	)

Create object for given number of ranges. The more is the number the more is precision

ZHistogram::ZHistogram ( const ZHistogram & zh )

Create exact copy of the object

Member Function Documentation

void ZHistogram::add_vector	(	const float *	items,
		unsigned	n_items
	)

Add vector of samples

unsigned ZHistogram::curve_data	(	float *&	arg,
		float *&	val,
		float	max = `0.0`
	)		const

Extract computed histogram - number of node points is returned. Resulted arg and val pointers are dynamically allocated and must be released by free(). Normalization to given maximum is performed in maximum is not zero.

float ZHistogram::get_hits ( float c[2] ) const

Get number of hits in given range of coordinate

float ZHistogram::get_hits ( int index ) const

Get number of hits in the ranges by given index. Out of range index returns 0.0

int ZHistogram::get_index ( float c ) const

Get index of the range containing given coordinate

void ZHistogram::get_range ( float mm[2] ) const

Get the whole histogram range

Logic ZHistogram::get_range	(	int	index,
		float	r[2]
	)		const

Get pair of coordinates for the cell with given index and return TRUE. For out of range index return FALSE

float ZHistogram::limit_hits_coord ( float part ) const

Return coordinate value which limits hits from 0 to it or from minus it to plus it (depending of mode) by given part (0.0 to 1.0)

ZHistogram& ZHistogram::operator= ( const ZHistogram & zh )

Assign one histogram to another by replacing previous contents of this one

void ZHistogram::reset ( )

Clean the histogram and prepare to build new one

void ZHistogram::reset ( ZHistMode hm )

Clean the histogram in new mode and prepare to build new one

ZHistogram& ZHistogram::unify ( const ZHistogram & zh )

Unify this histogram with given. Dimension of hits array will be rest the same, but bounds mm[] and step may be changed.
