DefaultHeatMapDataset(int xSamples, int ySamples, double minX, double maxX, double minY, double maxY) Creates a new dataset where all the z-values are initially 0. |
void | addChangeListener(DatasetChangeListener listener) Registers an object to receive notification of changes to the dataset. |
Object | clone() Returns an independent copy of this dataset. |
boolean | equals(Object obj) Tests this dataset for equality with an arbitrary object. |
Class> | getClass() Returns the runtime class of this Object . |
double | getMaximumXValue() Returns the highest x-value represented in this dataset. |
double | getMaximumYValue() Returns the highest y-value represented in this dataset. |
double | getMinimumXValue() Returns the lowest x-value represented in this dataset. |
double | getMinimumYValue() Returns the lowest y-value represented in this dataset. |
int | getXSampleCount() Returns the number of x values across the width of the dataset. |
int | getYSampleCount() Returns the number of y values (or samples) for the dataset. |
double | getZValue(int xIndex, int yIndex) Returns the z-value at the specified sample position in the dataset. |
void | setZValue(int xIndex, int yIndex, double z) Updates a z-value in the dataset and sends a DatasetChangeEvent to all registered listeners. |
void | setZValue(int xIndex, int yIndex, double z, boolean notify) Updates a z-value in the dataset and, if requested, sends a DatasetChangeEvent to all registered listeners. |
