Functions

func RGBString

func RGBString(r, g, b uint8) string

Types

type Axis

type Axis struct {
	Title string
	Unit  Unit
}

type Config

type Config struct {
	// Series contains the plots we want to show and how we want to show them.
	Series []interface{} `json:"series"`
	// Events contains a list of 'events time series' names. Series with
	// these names must be sent alongside other series. An event time series
	// is just made of timestamps with no associated value, each of which
	// gets plotted as a vertical line over another plot.
	Events []string `json:"events"`
}

type HeapmapHover

type HeapmapHover struct {
	YName string `json:"yname"`
	YUnit string `json:"yunit"` // 'duration', 'bytes' or custom
	ZName string `json:"zname"`
}

type Heatmap

type Heatmap struct {
	Name       string `json:"name"`
	Title      string `json:"title"`
