Functions

func XYUVRange

func XYUVRange(xyuvs XYUVer) (xmin, xmax, ymin, ymax, umin, umax, vmin, vmax float64)

XYUVRange returns the minimum and maximum x, y, u and v values.

Types

type Boxplots

type Boxplots []struct {
	X                        float64
	Min, Q1, Median, Q3, Max float64
	Outlier                  []float64
}

Boxplots implememnts the Boxplotter interface.

func (Boxplots) Boxplot

func (b Boxplots) Boxplot(i int) (x, min, q1, median, q3, max float64, outlier []float64)

func (Boxplots) Len

func (b Boxplots) Len() int

type Boxplotter

type Boxplotter interface {
	// Len returns the number of boxes.
	Len() int

	// Boxplot returns an data for the i'th boxplot.
	Boxplot(i int) (x, min, q1, median, q3, max float64, outlier []float64)
}

Boxplotter wraps the Len and Boxplot methods.

type XYTexter

type XYTexter interface {
	// Len returns the number of data points.
	Len() int

	// XYText returns a coordinate (x, y) and a string.
	XYText(int) (x, y float64, t string)
}

XYText wraps the Len and XYText methods.

type XYTexts

type XYTexts []struct {
	X, Y float64
	Text string
}

XYTexts implements the XYTexter interface.

func (XYTexts) Len

func (d XYTexts) Len() int

func (XYTexts) XYText

func (d XYTexts) XYText(i int) (x, y float64, text string)

type XYUVer

type XYUVer interface {
	// Len returns the number of x, y, u, v quadruples.
	Len() int

	// XYUV returns an x, y, u, v quadruple.
	XYUV(int) (x, y, u, v float64)
}

XYUVer wraps the Len and XYUV methods.

type XYUVs

type XYUVs []struct{ X, Y, U, V float64 }

XYUVs implements the XYUVer interface.

func (XYUVs) Len

func (d XYUVs) Len() int

func (XYUVs) XYUV

func (d XYUVs) XYUV(i int) (x, y, u, v float64)
