Class NormedXYSeries

java.lang.Object

com.androidplot.xy.NormedXYSeries

All Implemented Interfaces:

Series, XYSeries

public class NormedXYSeries
extends java.lang.Object
implements XYSeries

Wrapper implementation of XYSeries that wraps another XYSeries, normalizing values in the range of 0 to 1. Note that it's possible to push normed values outside of the standard 0, 1 range by applying a sufficiently large offset.

Constructor Detail

NormedXYSeries

public NormedXYSeries(XYSeries rawData)

Normalizes yVals only, auto calculating min/max.

Parameters:

rawData -

NormedXYSeries

public NormedXYSeries(XYSeries rawData,
                      NormedXYSeries.Norm x,
                      NormedXYSeries.Norm y)

Parameters:

rawData - The XYSeries to be normalized.

x - Normalization to apply to xVals. Set to null to disable normalization on the x axis.

y - Normalization to apply to yVals. Set to null to disable normalization on the y axis.

Method Detail
