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.
AA.
