DVT Gauge error display tabular data

Question

Hi,
I have a dvt:gauge and is related to backing bean to get the tabular data.
    public List getGaugeData()
        ArrayList list = new ArrayList();
        String[] rowLabels  = new String[] {"London", "Paris", "New York"};
        String[] colLabels  = new String[] {"Quota", "Sales", "Margin", "Costs", "Units"};
        double [] [] values = new double[][]{
            {60, 90, 135},
            {50, -100, -150},
            {130, 140, 150},
            {70, 80, -130},
            {110, 120, 130}
        for (int c = 0; c < colLabels.length; c++)
         for (int r = 0; r < rowLabels.length; r++)
            list.add (new Object [] {colLabels[c], rowLabels[r],
                new Double (values [c][r])});
        return list;
    }the result is wrong, rather than to have 3 gauge i am getting a lot more.
If you a sample to give is much appreciated.
How to solve this problem.
Regards

Hi,
Data Specification - A Data Specification can be used to specify columns or rows of data to be used as the metric value, and threshold, minimum and maximum values. The following example shows how to use a Data Specification for a set of tabular data. This tabular data contains 5 columns and 2 rows. If Data Specification is not used, the following table will generate 10 Gauges that there will be a gauge for each value. Each column has its desired data specification as shown. Sales is assigned to be metric value, Quota is assigned to be the first threshold, etc. This will generate 2 Gauges, one for Boston and one for Chicago, both with metric, minimum, maximum and threshold values specified.
Desired Spec. Metric Minimum Maximum Threshold 1 Threshold 2
Name Sales Min Inventory Quota Target
Boston 40 0 100 30 50
Chicago 60 0 80 35 70

Too bad there is no sample.
