Jfree Using custom names to categories - jfreechart

Question

I'm very new to Jfreechart, Please help me to get the solution for this, I'm using jfree to draw a graph for a categories which has specific code names like 563,258.855,etc... So i want to assign these values as labels to the domain axis, but by default it is assigning value1,value2,value3,etc... to categories.
But I wan to make it something like below
and here is my code,
final CategoryDataset dataset1 = DatasetUtilities.createCategoryDataset("Month to Date Occurences","value", data);
JFreeChart dualchart = ChartFactory.createBarChart(
"Top Ten Diagnostic Occurences", // chart title
"Category", // domain axis label
"Score", // range axis label
dataset1, // data
PlotOrientation.HORIZONTAL, // orientation
true, // include legend
true,
false
);
CategoryPlot plot = dualchart.getCategoryPlot();
plot.setRangeAxisLocation(AxisLocation.BOTTOM_OR_LEFT);
plot.setBackgroundPaint(Color.WHITE);
plot.setRangeGridlinePaint(Color.black);
BarRenderer renderer= (BarRenderer) plot.getRenderer();
renderer.setItemMargin(0.0);
CategoryAxis domainAxis = plot.getDomainAxis ();
domainAxis.setCategoryMargin(0.30); //distance between series
NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
rangeAxis.setRange(0.0, 100.0);
rangeAxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());
return dualchart;
Your suggestions are most welcome,
Thanks in advance.

You haven't included the code for dataset1 so it's hard to tell what the problem is but if you use something like this:
private static CategoryDataset createDataset() {
DefaultCategoryDataset dataset = new DefaultCategoryDataset();
dataset.addValue(15, "1", "451");
dataset.addValue(12, "1", "851");
dataset.addValue(10, "2", "362");
dataset.addValue(5, "2", "142");
return dataset;
}
You will get a chart like this:
