Interface CategoryItemLabelGenerator

All Known Implementing Classes:

IntervalCategoryItemLabelGenerator, StandardCategoryItemLabelGenerator

public interface CategoryItemLabelGenerator

A category item label generator is an object that can be assigned to a CategoryItemRenderer and that assumes responsibility for creating text items to be used as labels for the items in a CategoryPlot.

To assist with cloning charts, classes that implement this interface should also implement the PublicCloneable interface.

Method Detail

generateRowLabel

java.lang.String generateRowLabel(CategoryDataset dataset,
                                  int row)

Generates a label for the specified row.

Parameters:

dataset - the dataset (null not permitted).

row - the row index (zero-based).

Returns:

The label.

generateColumnLabel

java.lang.String generateColumnLabel(CategoryDataset dataset,
                                     int column)

Generates a label for the specified row.

Parameters:

dataset - the dataset (null not permitted).

column - the column index (zero-based).

Returns:

The label.

generateLabel

java.lang.String generateLabel(CategoryDataset dataset,
                               int row,
                               int column)

Generates a label for the specified item. The label is typically a formatted version of the data value, but any text can be used.

Parameters:

dataset - the dataset (null not permitted).

row - the row index (zero-based).

column - the column index (zero-based).

Returns:

The label (possibly null).
