import "github.com/watson-sam/rolling"

func main() {
	var samples = [10]float64{
		10, 4, 4, 32, 65, 6, 75, 22, 10, 22,
	}

	ro := rolling.NewRollingObject(3)

	for _, f := range samples {
		ro.Add(f)
	}

	ro.Calc("sum")     // => 54.0
	ro.Calc("avg")     // => 18.0
	ro.Calc("count")   // => 3.0
	ro.Calc("nunique") // => 2.0
	ro.Calc("min") // => 4.0
	ro.Calc("max") // => 75.0
}
