Fields

loga_labelf_ :: a -> String

The function used to show the axes labels.

defaultLinearAxis :: Show a => LinearAxisParams a

defaultLogAxis :: Show a => LogAxisParams a

autoScaledAxis :: RealFloat a => LinearAxisParams a -> AxisFn a

Generate a linear axis automatically, scaled appropriately for the input data.

autoScaledLogAxis :: RealFloat a => LogAxisParams a -> AxisFn a

Generate a log axis automatically, scaled appropriate for the input data.

autoSteps :: Int -> [Double] -> [Double]

Given a target number of values, and a list of input points, find evenly spaced values from the set {1*X, 2*X, 2.5*X, 5*X} (where X is some power of ten) that evenly cover the input points.
