Examples of org.jfree.chart.labels.StandardPieSectionLabelGenerator

org.jfree.chart.labels.StandardPieSectionLabelGenerator
A standard item label generator for plots that use data from a {@link PieDataset}.
For the label format, use {0} where the pie section key should be inserted, {1} for the absolute section value and {2} for the percent amount of the pie section, e.g. "{0} = {1} ({2})" will display as apple = 120 (5%).
