XYPlotXYBlockRenderer Field Summary final static  int DEFAULT_NUM_X      Default number of x values. final static  int DEFAULT_NUM_Y      Default number of y values. final static  int DEFAULT_POWER      Default power. Constructor Summary public   NonGridContourDataset()      Default constructor. public   NonGridContourDataset(String seriesName, Object[] xData, Object[] yData, Object[] zData)      Constructor for NonGridContourDataset. public   NonGridContourDataset(String seriesName, Object[] xData, Object[] yData, Object[] zData, int numX, int numY, int power)      Constructor for NonGridContourDataset. Method Summary protected  void buildGrid(int numX, int numY, int power)      Builds a regular grid. protected  double distance(double xDataPt, double yDataPt, double xGrdPt, double yGrdPt)      Calculates the distance between two points. Parameters:   xDataPt - the x coordinate. Parameters:   yDataPt - the y coordinate. Parameters:   xGrdPt - the x grid coordinate. Parameters:   yGrdPt - the y grid coordinate. Field Detail DEFAULT_NUM_X final static int DEFAULT_NUM_X(Code) Default number of x values. DEFAULT_NUM_Y final static int DEFAULT_NUM_Y(Code) Default number of y values. DEFAULT_POWER final static int DEFAULT_POWER(Code) Default power. Constructor Detail NonGridContourDataset public NonGridContourDataset()(Code) Default constructor. NonGridContourDataset public NonGridContourDataset(String seriesName, Object[] xData, Object[] yData, Object[] zData)(Code) Constructor for NonGridContourDataset. Uses default values for grid dimensions and weighting. Parameters:   seriesName - the series name. Parameters:   xData - the x values. Parameters:   yData - the y values. Parameters:   zData - the z values. NonGridContourDataset public NonGridContourDataset(String seriesName, Object[] xData, Object[] yData, Object[] zData, int numX, int numY, int power)(Code) Constructor for NonGridContourDataset. Parameters:   seriesName - the series name. Parameters:   xData - the x values. Parameters:   yData - the y values. Parameters:   zData - the z values. Parameters:   numX - number grid cells in along the x-axis Parameters:   numY - number grid cells in along the y-axis Parameters:   power - exponent for inverse distance weighting Method Detail buildGrid protected void buildGrid(int numX, int numY, int power)(Code) 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 Parameters:   numY - number grid points in along the y-axis Parameters:   power - exponent for inverse distance weighting distance protected double distance(double xDataPt, double yDataPt, double xGrdPt, double yGrdPt)(Code) Calculates the distance between two points. Parameters:   xDataPt - the x coordinate. Parameters:   yDataPt - the y coordinate. Parameters:   xGrdPt - the x grid coordinate. Parameters:   yGrdPt - the y grid coordinate. The distance between two points.
