Gantt chart Label value display

[nsurendiran]

Hi all,

I am displaying a Gantt for parking slot Utilization in a particular day. So My Series values will be something like below...

Code: Select all

DateFormat sdf = new SimpleDateFormat("HH:mm");
try{
s1.add(new Task("PS1",new SimpleTimePeriod(sdf.parse("00:00"), sdf.parse("23:59"))));
s1.add(new Task("PS2",new SimpleTimePeriod(sdf.parse("02:00"), sdf.parse("13:20"))));
s1.add(new Task("PS3",new SimpleTimePeriod(sdf.parse("08:00"), sdf.parse("09:20"))));
s1.add(new Task("PS4",new SimpleTimePeriod(sdf.parse("15:00"), sdf.parse("18:45"))));	
 }catch(ParseException pe){
      pe.printStackTrace();
 }

The Gantt is displayed ok.

Now I need to display the Vehicle registration number on each Gantt. So I 've decided to use Labels. There I have a problem
I am using a LabelGenerator,

Code: Select all

public String generateLabel(CategoryDataset dataset, int series,
		int category) {
		Number value = dataset.getValue(series, category);
		System.out.println(series +","+ category+","+value);
	}

The above output statement gives something like below

0,0,-19800000
0,1,-19800000
0,2,-19800000
0,3,-19800000
0,4,-19800000
0,5,10560000
0,6,-19800000
0,7,-19800000
0,8,11640000
0,9,-19800000
0,10,-19800000

Can someone help me to understand the 3rd value in each line?

Also, I need to display the label on the Gantt, currently its displayed above the Gantt. How can I position the label to display the value on the Gantt?

Any help would be appreciated

Thanks

Hi,

Ant thoughts on my first question, on how can I uniquely identify each Gantt in my chart.
I have String in my DomainAxis/Category and Time values in the RangeAxis. Please help me in this regards.
