Functions

func FillColor

func FillColor(value float64) string

FillColor returns string to be used for fill color

func Hash

func Hash(s string) string

Hash returns SHA-1 encryption of a string

func HexVal

func HexVal(str string, index, length int) float64

HexVal returns decimal representation of a substring of a hexa decimal string

func Map

func Map(value, aMin, aMax, bMin, bMax float64) float64

Map returns respective value of a number from a range to different range

func Merge

func Merge(mapA map[string]interface{}, mapB map[string]interface{}) map[string]interface{}

Merge merges two 'map' objects and returns the resultant object
