java.lang.Object

edu.rit.numeric.XYSeries

edu.rit.numeric.TransformedXYSeries

public class TransformedXYSeries
extends XYSeries

Class TransformedXYSeries provides an XYSeries that is formed by transforming the values in an underlying XYSeries. The underlying series consists of a list of pairs (x_i, y_i). The transformed series consists of a list of pairs (f₁(x_i), f₂(y_i)), where each of f₁ and f₂ is computed by a Function.

Constructor Detail

TransformedXYSeries

public TransformedXYSeries(XYSeries theSeries,
                           Function theXFunction,
                           Function theYFunction)

Construct a new transformed X-Y series.

Parameters:

theSeries - Underlying X-Y series.

theXFunction - Function for transforming the X values, or null not to transform the X values.

theYFunction - Function for transforming the Y values, or null not to transform the Y values.

Throws:

java.lang.NullPointerException - (unchecked exception) Thrown if theSeries is null.
