Types

type Histogram 

type Histogram struct {
	Name        string
	Bins        map[string]int
	Counts      map[string]int // how many items have counts.
	Percentages map[string]float64
}

Histogram is used to count how many times an item appears and how many times number of appearances appear. It can be used with simple string keys or `map[string]string` keys which are converted to soerted query strings.

func NewHistogram
