Examples of org.jfree.chart.title.LegendTitle

org.jfree.chart.title.LegendTitle
A chart title that displays a legend for the data in the chart.
The title can be populated with legend items manually, or you can assign a reference to the plot, in which case the legend items will be automatically created to match the dataset(s).
