  com.approximatrix.charting.model.MultiScatterDataModel.DataSet

Enclosing class:

MultiScatterDataModel

private class MultiScatterDataModel.DataSet
extends java.lang.Object

Implements a complete data set model that holds and manages X and Y values separately

Author:

armstrong

Field Summary

private java.util.ArrayList<java.lang.Double>	xvalues The data set's independent values
private java.util.ArrayList<java.lang.Double>	yvalues The data set's dependent values

Constructor Summary

MultiScatterDataModel.DataSet()
Initializes internal ArrayLists without setting any data

MultiScatterDataModel.DataSet(double[][] xy)
Creates a new data set from a single array containing both x and y values

MultiScatterDataModel.DataSet(double[] x, double[] y)
Creates a new data set from two vectors containing x and y values

Method Summary

double	getMaxX() Returns the largest independent value in the data set
double	getMaxY() Returns the largest dependent value in the data set
double	getMinX() Returns the smallest independent value in the data set
double	getMinY() Returns the smallest dependent value in the data set
double	getX(int i) Returns the specified independent value
double	getY(int i) Returns the specified dependent value
void	setXValue(double value, int i) Sets a single independent value at a specified location
void	setXValues(double[] inputs) Sets the independent values for this data set
void	setXYValues(double[][] inputs) Sets the independent and dependent values simultaneously
void	setYValue(double value, int i) Sets a single dependent value at a specified location
void	setYValues(double[] inputs) Sets the dependent values for this data set
int	size() Returns the number of entries in the data set
