Re: scatter plots

Ok, I guess I get to answer my own question. You add data to a 
ScatterPlotDataSet. I finally figured out that the createScatterPlotDataSet 
method in the ScatterPlotTestDriver was not really set up to create multiple 
datasets. This change to that method will create random data for any 
numberOfDataSets.

 private ScatterPlotDataSet createScatterPlotDataSet( int numberOfDataSets,
    int numberOfValuesToCreate, int xMinValue, int xMaxValue, int yMinValue,
    int yMaxValue ) throws ChartDataException
 {
 ScatterPlotDataSet scatterPlotDataSet= new 
ScatterPlotDataSet( this.getScatterPlotProperties( numberOfDataSets ) );
  Point2D.Double[] points;
  for( int i=0; i < numberOfDataSets; i++ ) {
   points= TestDataGenerator.getRandomPoints( numberOfValuesToCreate, 
xMinValue, xMaxValue, yMinValue, yMaxValue );
   Paint paint = TestDataGenerator.getRandomPaint();
   String[] legendLabels = TestDataGenerator.getRandomStrings( 1, 12, false );
   scatterPlotDataSet.addDataPoints( points, paint, legendLabels[ 0 ]  );
  }
  return scatterPlotDataSet;
 }
