StdMaps is a list of standard color maps

Functions ¶

func AvailMapsList ¶

func AvailMapsList() []string

AvailMapsList returns a sorted list of color map names, e.g., for choosers

Types ¶

type Map ¶

type Map struct {
	Name    string
	NoColor gist.Color   `desc:"color to display for invalid numbers (e.g., NaN)"`
	Colors  []gist.Color `desc:"list of colors to interpolate between"`
	Indexed bool         `` /* 215-byte string literal not displayed */
}

Map maps a value onto a color by interpolating between a list of colors defining a spectrum, or optionally as an indexed list of colors.

func (*Map) Map ¶

func (cm *Map) Map(val float64) gist.Color

Map returns color for normalized value in range 0-1. NaN returns NoColor which can be used to indicate missing values.

func (*Map) MapIndex ¶

func (cm *Map) MapIndex(val int) gist.Color

MapIndex returns color for given index, for scale in Indexed mode. NoColor is returned for values out of range of available colors. It is responsibility of the caller to use this method instead of Map based on the Indexed flag.
