Question

How to join the two axis line at the orgin in jfree line chart...

I've tried by using this code sample

final DefaultCategoryDataset lineDataset = new DefaultCategoryDataset();
        lineDataset.addValue(10, "Dep", "2009");
        lineDataset.addValue(11, "Dep", "2010");
        lineDataset.addValue(10, "Dep", "2011");
        lineDataset.addValue(10, "Dep", "2012");

        lineDataset.addValue(7, "Dia", "2009");
        lineDataset.addValue(7, "Dia", "2010");
        lineDataset.addValue(7, "Dia", "2011");
        lineDataset.addValue(7, "Dia", "2012");

        lineDataset.addValue(3, "HD", "2009");
        lineDataset.addValue(3, "HD", "2010");
        lineDataset.addValue(3, "HD", "2011");
        lineDataset.addValue(3, "HD", "2012");

        lineDataset.addValue(16, "HBP", "2009");
        lineDataset.addValue(15, "HBP", "2010");
        lineDataset.addValue(18, "HBP", "2011");
        lineDataset.addValue(17, "HBP", "2012");

        lineDataset.addValue(16, "HC", "2009");
        lineDataset.addValue(15, "HC", "2010");
        lineDataset.addValue(16, "HC", "2011");
        lineDataset.addValue(16, "HC", "2012");

        lineDataset.addValue(6, "LBP", "2009");
        lineDataset.addValue(7, "LBP", "2010");
        lineDataset.addValue(6, "LBP", "2011");
        lineDataset.addValue(6, "LBP", "2012");

        final JFreeChart chart = ChartFactory.createLineChart(
                "", // chart title
                "", // domain axis label
                "", // range axis label

                false, // tooltips
                false // urls
        );

        chart.setBackgroundPaint(Color.WHITE);
        final CategoryPlot plot = (CategoryPlot) chart.getPlot();
        plot.setBackgroundPaint(Color.WHITE);
        plot.setOutlineVisible(false);
        plot.setRangeGridlinePaint(Color.white);

        final CategoryAxis categoryAxis = plot.getDomainAxis();
        categoryAxis.setAxisLineVisible(true);

        categoryAxis.setLowerMargin(-0.1);

        categoryAxis.setTickLabelPaint(Color.decode("#222222"));
        chart.setPadding(new RectangleInsets(0, -8, 0, 0));

        final NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
        rangeAxis.setVisible(true);

        Shape circle = new Ellipse2D.Double(-3, -3, 6, 6);

//        renderer.setBaseItemLabelGenerator(new CustomLabelGenerator());
        renderer.setItemLabelAnchorOffset(-5);

        try {

            bi = chart.createBufferedImage(300, 100);

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            ImageIO.write(bi, "png", baos);
            byte[] byteArray = baos.toByteArray();

Add the line:

plot.setAxisOffset(new RectangleInsets(0,0,0,0));

to your code after

final CategoryPlot plot = (CategoryPlot) chart.getPlot();

Thankyou it works.... And another one, the axis is in the front of the point, is any other option to get the axis line to the back of the point? – Hariprasath Feb 11 '14 at 04:16
@Hariprasath Do you mean that the axis is plotted on top of the circle or that the circle is clipped off? You may be better asking new question. – GrahamA Feb 12 '14 at 15:47
