JavaScript / jQuery library for gantt like chart
===

I need to create a stacked bar chart showing the engine status in a day. Here is the example of what I would like to have: 


![enter image description here][1]

It looks like a gantt chart, but probably much simpler than a normal gantt chart. **I am badly looking for a JavaScript/jQuery charting library which supports this kind of chart.** I know lots of gantt chart library available, but wondering which library have the option/setting for the chart I want. 

My data would be in this format: 

    [
    	{
    		"day": "2009-07-13",
    		"work": ["11:16:35-12:03:12", "12:32:48-13:26:28", "13:39:09-13:39:12", "13:41:03-13:41:05", "14:18:09-24:00:00"]
    	}, {
    		"day": "2009-07-14",
    		"work": ["00:00:00-07:22:25", "07:22:25-07:22:28", "10:10:04-10:10:31", "10:10:32-10:15:33", "10:18:07-10:21:19", "11:04:49-11:06:15", "11:12:50-11:19:05", "11:19:11-11:19:19", "11:45:50-11:51:42", "11:51:43-11:53:55", "14:03:13-14:13:04", "14:23:55-14:31:28", "14:31:28-14:38:00", "14:38:00-14:49:04", "16:34:56-16:44:33", "16:46:37-16:48:10", "16:48:11-24:00:00"]
    	}, {
    		"day": "2009-07-15",
    		"work": ["00:00:00-08:16:23", "09:57:57-10:15:05"]
    	}, {
    		"day": "2009-07-16",
    		"work": ["10:02:40-10:05:56", "10:07:16-10:09:26", "10:09:27-10:09:28", "13:18:31-24:00:00"]
    	}, {
    		"day": "2009-07-17",
    		"work": ["00:00:00-08:56:41", "16:07:58-16:08:23"]
    	}, {
    		"day": "2009-07-20",
    		"work": ["14:44:47-14:48:35", "15:09:14-16:47:06", "16:47:05-16:47:10", "16:47:13-16:47:15", "16:47:16-16:47:20"]
    	}, {
    		"day": "2009-07-21",
    		"work": ["10:52:51-16:37:07"]
    	}, {
    		"day": "2009-07-24",
    		"work": ["14:54:38-16:03:07", "16:16:23-16:35:14", "16:35:17-16:41:22", "16:43:37-23:56:37"]
    	}, {
    		"day": "2009-07-25",
    		"work": ["20:36:34-21:24:28", "21:24:43-23:45:53"]
    	}, {
    		"day": "2009-07-26",
    		"work": ["13:46:59-18:09:09"]
    	}, {
    		"day": "2009-07-28",
    		"work": ["13:48:30-13:51:10", "13:51:18-13:51:27", "13:52:17-14:57:31"]
    	}, {
    		"day": "2009-07-29",
    		"work": ["14:50:15-14:50:16", "15:36:17-15:43:51", "15:53:31-16:29:30", "16:57:50-23:07:28"]
    	}, {
    		"day": "2009-07-30",
    		"work": ["11:25:29-11:41:32", "16:06:37-16:33:09", "21:14:04-21:20:18", "21:53:57-22:18:59"]
    	}
    ]

The `work` attribute time slot is when the engine is working, the slots between `work` time slots is when the engine is off. 

Have been looking for this for long. Any suggestion would be greatly appreaciated!
