Returns: The highest x-value represented in this dataset.
Returns: The highest y-value represented in this dataset.
Returns: The lowest x-value represented in this dataset.
Returns: The lowest y-value represented in this dataset.
Returns: The number of x-values (always > 0).
Parameters: xIndex the xIndex.
Returns: The x-value.
Returns: The number of y-values (always > 0).
Parameters: yIndex the yIndex.
Returns: The y-value.

object to be allocated...
for this reason, it is generally preferable to use the
HeatMapDataset method unless you *know* that the dataset
implementation stores the z-values using objects.
Parameters: xIndex the position of the x sample in the dataset. yIndex the position of the y sample in the dataset.
Returns: The z-value (possibly null
).
Parameters: xIndex the position of the x sample in the dataset. yIndex the position of the y sample in the dataset.
Returns: The z-value.
