scatter plots

Hi,

Could anybody tell me whats wrong with the following code to plot a scatter plot. It doesnt show the data points. The title, legends and axis titles diplay correclty though.

Thanks
Deepa


public void scatterChartDraw(BaseXWPropertyMap view, ChartDataSet cData, BaseXWPropertyMap style) throws ChartDataException, PropertyException
 {
  
    
  String[] xAxisLabels = { "1998", "1999", "2000", "2001",
                                     "2002", "2003", "2004" };
   String xAxisTitle = "Years";
   String yAxisTitle = "Problems";
   String title = "Microsoft at Work";
   DataSeries dataSeries = new DataSeries(xAxisLabels, xAxisTitle,
     yAxisTitle, title );
   
   double[][] data = new double[][]{ {250, 45, 36, 66, 145, 80, 55} };
   String[] legendLabels = { "Bugs" };
   Paint[] paints = {Color.pink};
   
   Stroke[] strokes = { ScatterPlotProperties.DEFAULT_LINE_STROKE };
   Shape[]  shapes = { PointChartProperties.SHAPE_DIAMOND};
   ScatterPlotProperties properties =
    new ScatterPlotProperties(strokes, shapes);
   
   AxisChartDataSet axisChartDataSet =
    new AxisChartDataSet(data, legendLabels, paints,
      ChartType.SCATTER_PLOT, properties );
   dataSeries.addIAxisPlotDataSet (axisChartDataSet);
   
   ChartProperties chartProperties   = new ChartProperties();
   chartProperties.setBackgroundPaint((Paint) Color.yellow); 
   chartProperties.setBorderStroke( (ChartStroke) ChartStroke.DEFAULT_AXIS ); 
   
   AxisProperties axisProperties     = new AxisProperties();
   LegendProperties legendProperties = new LegendProperties();
   
   AxisChart axisChart= new AxisChart(dataSeries, chartProperties,
     axisProperties, legendProperties,
    width, height);
 
   this.exportImage( axisChart, filePath );
  

 }
