Labels

[jaypee]

Currently I'm using this to add labels to my chart:

Code: Select all

                    plot.getRenderer().setSeriesPaint(0, Color.blue);
                    plot.getRenderer().setItemLabelGenerator(new StandardCategoryItemLabelGenerator());
                    plot.getRenderer().setItemLabelFont(new Font("Arial",Font.PLAIN,8));
                    plot.getRenderer().setItemLabelsVisible(true);
                    plot.getRenderer().setItemLabelPaint(Color.MAGENTA);

but with these, it puts labels on all the points.
Is there a way to put labels only on the points I specify?

hmmm it looks like we're looking for the same thing.
will keep you informed if I find...

One way would be to implement your own label generator that only returns a label for the items you want (this means the generator will have to have some mechanism for determining which items should have labels, perhaps a look-up table).

Thanks

What methods do I need to override?

Code: Select all

   
public class MyPieSectionLabelGenerator implements PieSectionLabelGenerator {

      public String generateSectionLabel(PieDataset dataset, Comparable key) {
         return ...;
      }
      
      public AttributedString generateAttributedSectionLabel(PieDataset dataset, Comparable key) {            
          return null;
      }
   }

For CategoryDataset you should extend the StandardCategoryItemLabelGenerator and overwrite the generateLabels() method.
