Constructor Detail

### NonGridContourDataset

    public NonGridContourDataset()

  Deprecated.
  Default constructor.

### NonGridContourDataset

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

  Deprecated.
  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.

### NonGridContourDataset

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

  Deprecated.
  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

Method Detail

### buildGrid

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

  Deprecated.
  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

### distance

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

  Deprecated.
  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.
