Hide labels on jfreechart/PiePlot3D piechart

I'm trying to get the jfreechart PieChart3D to hide labels. I can't find anything in the documentation.

Anyone know how to do this?

<% response.setContentType("image/png"); %><%@page import="org.jfree.data.general.*"%><%@page import="org.jfree.chart.*"%><%@page import="org.jfree.chart.plot.*"%><%@page import="java.awt.Color" %><%

            DefaultPieDataset ds = (DefaultPieDataset)session.getAttribute("usagePieOutputDataset");

            JFreeChart chart = ChartFactory.createPieChart3D
            (
                null,   // Title
                ds,     // Dataset
                false,  // Show legend
                false,  // Use tooltips
                false   // Configure chart to generate URLs?
            );

            chart.setBackgroundPaint(Color.WHITE);
            chart.setBorderVisible(false);

            PiePlot3D plot = ( PiePlot3D )chart.getPlot();
            plot.setDepthFactor(0.0);
            plot.setLabelOutlinePaint(Color.LIGHT_GRAY);
            plot.setLabelFont(new java.awt.Font("Arial",  java.awt.Font.BOLD, 10));


            ChartUtilities.writeChartAsPNG(response.getOutputStream(), chart, 150, 144);
    %>

Solution

  • This will hide all labels:

    plot.setLabelGenerator(null); //null means no labels
