Hello!
I'm new to JCharts.
I'm trying to modify the "ScatterPlotChartServlet" example to do what I 
need.

The actual code in "ScatterPlotChartServlet" looks like the following:

   private ScatterPlotDataSet createScatterPlotDataSet() {
       Point2D.Double[] points = new Point2D.Double[ 20 ];
       Point2D.Double[] points2 = new Point2D.Double[ 20 ];
       for( int x = 0; x < 20; x++ ) {
           //--- y = x2
           points[ x ] = ScatterPlotDataSet.createPoint2DDouble();
           points[ x ].setLocation( x, Math.pow(x,2 ) );        }
       ScatterPlotDataSet scatterPlotDataSet = new ScatterPlotDataSet( 
this.createScatterPlotProperties() );
       scatterPlotDataSet.addDataPoints( points, Color.red, 
"Proprietary" );
       return scatterPlotDataSet;
   }
    Me, I'd like to draw 3 graphs, for instance  :
y=Math.pow(x,2)
y=Math.pow(x,3)
y=Math.sin(Math.PI*x)
on the SAME chart.

My question is: How can I modify the code of the 
"ScatterPlotChartServlet" above to have 3 graphs on the SAME chart?
creating two others points2[] and points3[]  objects for the 2 remaining 
graphs did not help.

Thanks.

Arcadius.
