Box and whisper not plotting the lines for some values Out of 5 lines I see only one sometimes. Please tell me the scenario where I get the far or low triangles
  DefaultBoxAndWhiskerCategoryDataset dataset = new DefaultBoxAndWhiskerCategoryDataset();
    List<Double> values = new ArrayList();
    values.add(14);
    values.add(14);
    values.add(14);
    values.add(14);
    dataset.add(values, "","");
    BoxAndWhiskerRenderer r = new BoxAndWhiskerRenderer();
    CategoryPlot plot = new CategoryPlot(dataset, new CategoryAxis("x"),
            new NumberAxis("y"), r);
    JFreeChart chart = new JFreeChart(plot);
Mean is same as q1 so it's not coming
