Scatter Charts

Charts that display a set of unconnected data points.

Scatter charts display a set of unconnected data points. The name refers to given X and Y coordinates, so the DataSeries or DataProviderSeries are usually the most meaningful data series types for scatter charts.

Scatter Chart

The chart type of a scatter chart is ChartType.SCATTER. Its options can be configured in a PlotOptionsScatter object, although it doesn’t have any chart-type-specific options.

Source code
Java
Chart chart = new Chart(ChartType.SCATTER);

// Modify the default configuration a bit
Configuration conf = chart.getConfiguration();
conf.setTitle("Random Sphere");
conf.getLegend().setEnabled(false); // Disable legend
conf.getxAxis().setTitle("X");
conf.getyAxis().setTitle("Y");
conf.getxAxis().setMax(1);
conf.getxAxis().setMin(-1);
conf.getyAxis().setMax(1);
conf.getyAxis().setMin(-1);

PlotOptionsScatter options = new PlotOptionsScatter();
// ... Give general plot options here ...
conf.setPlotOptions(options);

DataSeries series = new DataSeries();
for (int i=0; i<300; i++) {
    double lng = Math.random() * 2 * Math.PI;
    double lat = Math.random() * Math.PI - Math.PI/2;
    double x   = Math.cos(lat) * Math.sin(lng);
    double y   = Math.sin(lat);

    DataSeriesItem point = new DataSeriesItem(x,y);
    series.add(point);
}
conf.addSeries(series);

The result is shown in Scatter Chart.
