I am trying to add a new item or label in the legend, this item is not available in dataset. Which method should be used to add this item to legend?
From the jfree forum :
Adding Legends on Bar Chart for custom colors:
LegendItemCollection chartLegend = new LegendItemCollection();
Shape shape = new Rectangle(10, 10);
chartLegend.add(new LegendItem("label1", null, null, null, shape, Color.red));
chartLegend.add(new LegendItem("label2", null, null, null, shape, Color.blue));
plot.setFixedLegendItems(chartLegend);
