Interface AxisTransform

All Known Implementing Classes:
AxisTransformBusinessCalendar, AxisTransformLambda, AxisTransforms
public interface AxisTransform
Function applied to transform data before plotting. For example, a log plot is a logarithmic transform of an axis. Determines how dataset values are displayed in the plot by transforming dataset values into Axis space and back. For example, if the forward transform is x -> x^0.5, a dataset value of 1 maps to 1 in Axis space; a dataset value of 4 maps to 2. In the plot these values will be displayed close together.
