How to change color of particular sub-task in JFreeChart Gantt Chart?
I have a Gantt Chart with 5 tasks. Each task is divided into 3 sub-tasks. I need to define different color for each sub-task, e.g. Sub-task1: "light blue", Sub-task2: "blue", Sub-task3: "dark blue". I tried to google some examples, but I didn't find any full working example. Thanks.

Update#1:
I'm using IntervalCategoryDataset for the dataset. 

    IntervalCategoryDataset dataset = createDataset(data);

    final Task t = new Task("Resource " + i, date(time11), date(time14));
    t.addSubtask(new Task("Resource " + i, date(time11), date(time12)));
    t.addSubtask(new Task("Resource " + i, date(time12), date(time13)));
    t.addSubtask(new Task("Resource " + i, date(time13), date(time14)));
