Extending StandardXYItemLabelGenerator is often a useful approach, but the supplied constructors may suffice. For this generator, the MessageFormat ArgumentIndex values correspond to the series name, domain and range.

NumberFormat format = NumberFormat.getNumberInstance();
format.setMaximumFractionDigits(2); // etc.
XYItemLabelGenerator generator =
    new StandardXYItemLabelGenerator("{0} {1} {2}", format, format);
renderer.setBaseItemLabelGenerator(generator);
renderer.setBaseItemLabelsVisible(true);

In addition, you can control individual series labeling with

renderer.setSeriesItemLabelsVisible(true);
