)

Increment the contents of the bin containg the argument by 1

Parameters:

x

abszissa value of the bin to be incremented

int Histo::fill	(	float	x,
		float	weight
	)

Increments the contents of the bin containg the first argument by the weight argument (1-dimensional histograms)
OR
Increments the bin contents of the bin containing the pair (x,weight) of a 2-dimentional histogram by 1

Parameters:

	x	abszissa value of the bin to be incremented
	weight	increment of the bin contents (1-dimentional histograms) OR ordinate value of the bin to be incremented (2-dimentional histograms)

int Histo::fill	(	float	x,
		float	y,
		float	weight
	)

Increments the contents of the bin containg the first two argument by the weight argument This signature is only valid for 2-dimensional histograms

Parameters:

	x	abszissa value of the bin to be incremented
	y	ordinate value of the bin to be incremented
	weight	increment of the bin contents
