Public Constructors

public NonGridContourDataset ()

Default constructor.

public NonGridContourDataset (String seriesName, Object[] xData, Object[] yData, Object[] zData)

Constructor for NonGridContourDataset. Uses default values for grid dimensions and weighting.

Parameters

seriesName	the series name.
xData	the x values.
yData	the y values.
zData	the z values.

public NonGridContourDataset (String seriesName, Object[] xData, Object[] yData, Object[] zData, int numX, int numY, int power)

Constructor for NonGridContourDataset.

Parameters

seriesName	the series name.
xData	the x values.
yData	the y values.
zData	the z values.
numX	number grid cells in along the x-axis
numY	number grid cells in along the y-axis
power	exponent for inverse distance weighting

Protected Methods

protected void buildGrid (int numX, int numY, int power)

Builds a regular grid. Maps the non-grid data into the regular grid using an inverse distance between grid and non-grid points. Weighting of distance can be controlled by setting through the power parameter that controls the exponent used on the distance weighting (e.g., distance^power).

Parameters

numX	number grid points in along the x-axis
numY	number grid points in along the y-axis
power	exponent for inverse distance weighting

protected double distance (double xDataPt, double yDataPt, double xGrdPt, double yGrdPt)

Calculates the distance between two points.

Parameters

xDataPt	the x coordinate.
yDataPt	the y coordinate.
xGrdPt	the x grid coordinate.
yGrdPt	the y grid coordinate.

Returns

The distance between two points.
