scaledAxis :: RealFloat a => LinearAxisParams a -> (a, a) -> AxisFn a Source

Generate a linear axis with the specified bounds

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

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

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

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

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

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.

la_labelf :: forall a a. Lens (LinearAxisParams a) (LinearAxisParams a) (a -> String) (a -> String) Source

la_nLabels :: forall a. Lens' (LinearAxisParams a) Int Source

la_nTicks :: forall a. Lens' (LinearAxisParams a) Int Source

loga_labelf :: forall a a. Iso (LogAxisParams a) (LogAxisParams a) (a -> String) (a -> String) Source
