Constructor Detail

AbstractCategoryItemRenderer

protected AbstractCategoryItemRenderer()

Creates a new renderer with no tool tip generator and no URL generator. The defaults (no tool tip or URL generators) have been chosen to minimise the processing required to generate a default chart. If you require tool tips or URLs, then you can easily add the required generators.

Method Detail

getPassCount

public int getPassCount()

Returns the number of passes through the dataset required by the renderer. This method returns 1, subclasses should override if they need more passes.

Specified by:

getPassCount in interface CategoryItemRenderer

Returns:

The pass count.

getPlot

public CategoryPlot getPlot()

Returns the plot that the renderer has been assigned to (where null indicates that the renderer is not currently assigned to a plot).

Specified by:

getPlot in interface CategoryItemRenderer

Returns:

The plot (possibly null).

See Also:

setPlot(CategoryPlot)

setPlot

public void setPlot(CategoryPlot plot)

Sets the plot that the renderer has been assigned to. This method is usually called by the CategoryPlot, in normal usage you shouldn't need to call this method directly.

Specified by:

setPlot in interface CategoryItemRenderer

Parameters:

plot - the plot (null not permitted).

See Also:

getPlot()

getItemLabelGenerator

public CategoryItemLabelGenerator getItemLabelGenerator(int row,
                                                        int column)

Returns the item label generator for a data item. This implementation simply passes control to the getSeriesItemLabelGenerator(int) method. If, for some reason, you want a different generator for individual items, you can override this method.

Specified by:

getItemLabelGenerator in interface CategoryItemRenderer

Parameters:

row - the row index (zero based).

column - the column index (zero based).

Returns:

The generator (possibly null).
