Description

Scale training: turn a declarative Scale into a TrainedScale that projects data values onto [0,1] and generates round-number ticks.

Synopsis

data TrainedScale = TrainedScale {
- tsDomain :: !(Double, Double)
- tsProject :: !(Double -> Double)
- tsUnproject :: !(Double -> Double)
- tsBreaks :: ![Double]
- tsLabels :: ![Text]
}
train :: Scale -> (Double, Double) -> TrainedScale
niceTicks :: (Double, Double) -> Int -> [Double]
niceNum :: Double -> Bool -> Double
