Class org.jfree.chart.labels.StandardCategoryItemLabelGenerator

Examples of org.jfree.chart.labels.StandardCategoryItemLabelGenerator.generateLabel()

org.jfree.chart.labels.StandardCategoryItemLabelGenerator.generateLabel()
Generates the label for an item in a dataset. Note: in the current dataset implementation, each row is a series, and each column contains values for a particular category. @param dataset the dataset (null not permitted). @param row the row index (zero-based). @param column the column index (zero-based). @return The label (possibly null).
