type ScaleModifier = ContinuousScale -> ContinuousScale

A scale modifier transforms a scale while preserving its type

niceModifier :: ScaleModifier

Modifier that makes the domain nice (rounds to clean values)

clampModifier :: ScaleModifier

Modifier that enables clamping

roundModifier :: ScaleModifier

Modifier that enables rounding

combineModifiers :: Array ScaleModifier -> ScaleModifier

Combine multiple modifiers (apply left to right)

sample :: Int -> ContinuousScale -> Array Number

Sample a scale at n evenly-spaced points in [0, 1]

sampleRange :: Int -> Number -> Number -> ContinuousScale -> Array Number

Sample within a specific range

sampleWithDomain :: Int -> ContinuousScale -> Array (Tuple Number Number)

Sample and return both domain and range values

tickPositions :: Int -> ContinuousScale -> Array Number

Get tick positions as pixel coordinates

tickLabels :: Int -> String -> ContinuousScale -> Array String

Get formatted tick labels

ticksWithLabels :: Int -> String -> ContinuousScale -> Array { label :: String, position :: Number }

Get ticks with both position and label

blendInterpolators :: Number -> Interpolator String -> Interpolator String -> Interpolator String

Blend two interpolators together

reverseInterpolator :: forall a. Interpolator a -> Interpolator a

Reverse an interpolator (1-t instead of t)

clampInterpolator :: forall a. Interpolator a -> Interpolator a

Clamp interpolator input to [0, 1]

cycleInterpolator :: forall a. Interpolator a -> Interpolator a

Make an interpolator cycle (values outside [0,1] wrap)

normalize :: Number -> Number -> ContinuousScale

Create a normalizing scale (maps domain to [0, 1])

quantize :: forall a. NonEmptyArray a -> Number -> Number -> Number -> a

Create a quantizing scale (continuous -> discrete buckets)

threshold :: forall a. Array Number -> NonEmptyArray a -> Number -> a

Create a threshold scale with custom breakpoints

scaleExtent :: ContinuousScale -> { max :: Number, min :: Number }

Get the extent (min, max) of a scale's output for inputs in [0, 1]

scaleMidpoint :: ContinuousScale -> Number

Get the midpoint of a scale

scaleInRange :: ContinuousScale -> Number -> Boolean

Check if a value is within a scale's output range
