[jCharts-developers] ScatterPlot with two set of values

[KUMARARAJA S. <SKu...@co...>]

Hi,

=20

We need to draw a graph with plots of two different value sets having
different shapes and colors for those two value sets.

The present method supports only one dataset.

=20

                        double maxX=3D0,maxY=3D0,minX=3D0,minY=3D0;

                        Point2D.Double[] points =3D new
Point2D.Double[TotItems];

=20

                        for (int iCount=3D0;iCount<TotItems;iCount++ )

                        {

                                    points[iCount] =3D
ScatterPlotDataSet.createPoint2DDouble();

=20
points[iCount].setLocation(xAxis[iCount], yAxis[iCount]);

                                    if (xAxis[iCount] > maxX)
maxX=3DxAxis[iCount];

                                    if (yAxis[iCount] > maxY)
maxY=3DyAxis[iCount];

                                    if (yAxis[iCount] < minY)
minY=3DyAxis[iCount];

                        }

                       =20

                        Stroke[] strokes =3D new Stroke[]{new
BasicStroke()};

                        Shape[] shapes =3D new Shape[]{new Polygon( new
int[]{0, 5, 10, 5}, new int[]{5, 0, 5, 10}, 4 )};

=20

                        ScatterPlotDataSet scatterPlotDataSet =3D new
ScatterPlotDataSet( new ScatterPlotProperties( strokes, shapes ) );

                        scatterPlotDataSet.addDataPoints( points,
Color.blue, null );

=20

                        ScatterPlotDataSeries scatterPlotDataSeries =3D
new ScatterPlotDataSeries( scatterPlotDataSet,xAxisTitle,yAxisTitle,null
);

                        DataAxisProperties xAxisProperties =3D new
DataAxisProperties();

=20

/*********The DataSeries created as in the above code is passed as in
the below code.**************/

=20

                        ScatterPlotAxisChart scatterPlotAxisChart =3D =
new
ScatterPlotAxisChart(
scatterPlotDataSeries,chartProperties,axisProperties,legendProperties,wi
dth*2,height*2 );

=20

                        bufferedImage =3D new BufferedImage(
scatterPlotAxisChart.getImageWidth(),
scatterPlotAxisChart.getImageHeight(), BufferedImage.TYPE_INT_RGB );

                        scatterPlotAxisChart.setGraphics2D(
bufferedImage.createGraphics() );

                        scatterPlotAxisChart.render();

=20

Pls let us know how this can be achieved.

Hey! shalini

u check out through jfreecharts >>
tht's also another way to achive all this >> bar charts, stacked bar charts,
pie charts and time charts

if u need a jar then i am having >> let me know >> even u can get that from
google!!!

bye!

thanks and regards
