How to adjust the xand y axis line in jfreecharts

Question

In my jfree line chart the x and y axis line is drawn seperated.. I need to get both the axis meet at the orgin. Here is the Actual Image im getting from jfree line chart

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

Add the line:

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

to your code after

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