NumericalScale Class

Use the NumericalScale class to represent a categorization of a range of numerical values. The categories are contiguous intervals on a range of real numbers that may be infinite.

There are two ways to supply the intervals. The first is to supply an array containing the boundaries of the intervals. Every value except the first and the last acts both as the upper bound of one interval and the lower bound of the next. The second way is to supply an interval and a number of intervals. In this case, the interval is divided into the specified number of subintervals, each corresponding to a category.

NumericalScale inherits from CategoricalScale. The intervals of the NumericalScale correspond to the levels of the CategoricalScale.

The Map(Object) method maps a real number to an interval. Overloads are available that map many values in one operatioin

Using a NumericalScale, a NumericalVariable can be transformed into a CategoricalVariable. A NumericalScale object is also used by the Histogram class to map values to histogram bins.
