obj - the object (null permitted).
Returns:
A boolean.

findDomainBounds

public Range findDomainBounds(XYDataset dataset)
Returns the lower and upper bounds (range) of the x-values in the specified dataset.
Specified by:
findDomainBounds in interface XYItemRenderer
Overrides:
findDomainBounds in interface AbstractXYItemRenderer
Parameters:
dataset - the dataset (null permitted).
Returns:
The range (null if the dataset is null or empty).

findRangeBounds

public Range findRangeBounds(XYDataset dataset)
Returns the range of values the renderer requires to display all the items from the specified dataset.
Specified by:
findRangeBounds in interface XYItemRenderer
Overrides:
findRangeBounds in interface AbstractXYItemRenderer
Parameters:
dataset - the dataset (null permitted).
Returns:
The range (null if the dataset is null or empty).
