The Transformation class is never itself instantiated. However, it does provide some basic resources that its subclasses may use to specify the extent and direction of the data space. Currently there are three subclasses of the Transformation class:
1. When line interpolation is turned on, the quality of the interpolation into data space is not always very good, particularly for log plots.
