fill()

template<typename T >

bool ExpressionHisto< T >::fill	(	const T &	element,
		double	weight = 1.0,
		uint32_t	i = 0
	)

Plot the quantity for the specified element and index. Returns true if the quantity has been plotted, false otherwise. A return value of "false" means "please don't send any more elements". The default "i = 0" is to keep backwards compatibility with usages outside HistoAnalyzer
