Types ¶

type BrokenColorMap ¶

type BrokenColorMap struct {
	Base, OverFlow palette.ColorMap
}

func (*BrokenColorMap) Alpha ¶

func (c *BrokenColorMap) Alpha() float64

Alpha returns the opacity value of the ColorMap.

func (*BrokenColorMap) At ¶

func (c *BrokenColorMap) At(v float64) (color.Color, error)

At returns the color associated with the given value. If the value is not between Max() and Min(), an error is returned.

func (*BrokenColorMap) Max ¶

func (c *BrokenColorMap) Max() float64

Max returns the current maximum value of the ColorMap.

func (*BrokenColorMap) Min ¶

func (c *BrokenColorMap) Min() float64

Min returns the current minimum value of the ColorMap.

func (*BrokenColorMap) Palette ¶

func (c *BrokenColorMap) Palette(colors int) palette.Palette

Palette creates a Palette with the specified number of colors from the ColorMap.

func (*BrokenColorMap) SetAlpha ¶

func (c *BrokenColorMap) SetAlpha(v float64)

SetAlpha sets the opacity value of the ColorMap. Zero is transparent and one is completely opaque. The default value of alpha should be expected to be one. The function should be expected to panic if alpha is not between zero and one.

func (*BrokenColorMap) SetHighCut ¶

func (c *BrokenColorMap) SetHighCut(v float64)

SetHighCut sets the cut point for switching between the base and overflow color maps.

func (*BrokenColorMap) SetMax ¶

func (c *BrokenColorMap) SetMax(v float64)

SetMax sets the maximum value of the ColorMap.

func (*BrokenColorMap) SetMin ¶

func (c *BrokenColorMap) SetMin(v float64)

SetMin sets the minimum value of the ColorMap.

type BrokenScale ¶

type BrokenScale struct {
	HighCut         float64
	HighCutFraction float64
}

BrokenScale can be used as the value of an Axis.Scale function to set the axis to a linear scale with a break.

func (BrokenScale) Normalize ¶

func (b BrokenScale) Normalize(min, max, x float64) float64

Normalize returns the fractional broken distance of x between min and max.

type BrokenTicks ¶

type BrokenTicks struct {
	// HighCut is the location of the break in the scale
	HighCut float64

	// MaxFormat is the string format for the tick at the maximum value.
	// All other ticks will be formatted using plot.DefaultTicks.
	MaxFormat string
}

BrokenTicks creates ticks appropriate for a broken scale.

func (BrokenTicks) Ticks ¶

func (b BrokenTicks) Ticks(min, max float64) []plot.Tick
