Replace your createDataset() with something like this:

private static CategoryDataset createDataset() {
    DefaultCategoryDataset dataset = new DefaultCategoryDataset();
    dataset.addValue(40.0,"Expediture","House");
    dataset.addValue(30.0,"Expediture","Office Rent");
    dataset.addValue(-20.5,"Expediture","Food");
    dataset.addValue(30.0,"Expediture","Other");
    dataset.addValue(6.0,"Expediture","Etc");
    return dataset;
}
