		OBJECT	last,
		const std::string &	title,
		const double	low,
		const double	high,
		const unsigned long	bins,
		const WEIGHT &	weight
	)		const `[inline]`

book and fill the 1D histogram with information from [first,last) sequence with given weight

  std::vector<double> v = ... ;

  plot( sin                 ,   // function
        v.begin() , v.end() ,   // sequence
        " bla-bla "         ,   // title
        -1. , 1.0           ,   // low and high limits
        100                 ,   // number of bins
        tanh                );  // weight function

The histogram will get a unique integer identifier automatically assigned

Sequence, objects and function can be non-trivial:

  Particles* p = ... ;

  plot( PT                  ,  // function
        p->begin()  , p->end() , // sequence
        " bla-bla "         ,   // title
        -1. , 1.0           ,   // low and high limits
        100                 ,   // number of bins
        MASS                ) ; // weight function

where PT and MASS can be any function or function object for which the expressions PT(p) and MASS with p of type Particle* have some sense and can be evaluated to the values, which is convertible to double

Note : These plot methods using iterator ranges are more efficient than the simplier "value" only methods, since the associated histogram only requires locating from internal storage once per loop, as opposed to once per fill for the simplier functions. It is recommended to use these whenever possible.

        100                 );  // number of bins

Sequence, objects and function can be non-trivial:

        p->begin()   , p->end() , // sequence

        100                 ) ; // number of bins

Note : These plot methods using iterator ranges are more efficient than the simplier "value" only methods, since the associated histogram only requires locating from internal storage once per loop, as opposed to once per fill for the simplier functions. It is recommended to use these whenever possible.

Note : This method is more efficient that the similar method without forced ID, since the histogram lookup is faster using a numerical ID.

where PT can be any function or function object for which the expression PT(p) , with p of type Particle* have some sense and can be evaluated to the values, which is convertible to double

Note : These plot methods using iterator ranges are more efficient than the simplier "value" only methods, since the associated histogram only requires locating from internal storage once per loop, as opposed to once per fill for the simplier functions. It is recommended to use these whenever possible.

where PT and MASS can be any function or function object for which the expressions PT(p) and MASS with p of type Particle* have some sense and can be evaluated to the values, which is convertible to double

fill the 1D histogram (book on demand)

     const double mass = ... ;
     plot1D( mass , "Invariant Mass" , 2.5 , 3.5 , 100 )

This example illustrates the filling of the histogram titled "InvariantMass" with value mass .
If the histogram with given title does not exist yet it will be automatically booked with parameters low equal to 2.5, parameters high equal to 3.5 and bins equal to 100.

The histogram will get a unique integer identifier automatically assigned.

fill the 1D histogram with forced ID assignement (book on demand)

     const double mass = ... ;
     plot1D( mass , 15 , "Invariant Mass" , 2.5 , 3.5 , 100 )

This example illustrates the filling of the 1D histogram ID=15 titled "Invariant Mass" with value mass .
If the histogram with given ID does not exist yet it will be automatically booked with parameters low equal to 2.5, parameters high equal to 3.5 and bins equal to 100.

Attention:: If the histogram with given ID is already booked through automatic assignement of histogram ID, the error will not be detected. Therefore it is recommended to use non-trivial histogram ID offset (property "HistoOffSet") if one need to combine these techniques together It is still desirable to use the unique histogram title to avoid a bad interference.

Note : This method is more efficient that the similar method without forced ID, since the histogram lookup is faster using a numerical ID.
