public AreaPlot() {
	// Generate data
	DataTable data = new DataTable(Double.class, Double.class, Double.class, Double.class);
	for (double x = 0.0; x < 50; x ++) {
		double y1 = Double.NaN, y2 = Double.NaN, y3 = Double.NaN;
		y1 = random.nextGaussian();
		y2 = random.nextGaussian();
		y3 = random.nextGaussian();
		data.add(x, y1, y2, y3);
	}

	// Create data series
	DataSeries data1 = new DataSeries("series 1", data, 0, 1);
	DataSeries data2 = new DataSeries("series 2", data, 0, 2);
	DataSeries data3 = new DataSeries("series 3", data, 0, 3);

	// Create new xy-plot
	XYPlot plot = new XYPlot(data1, data2, data3);
	plot.setLegendVisible(true);
	plot.setInsets(new Insets2D.Double(20.0, 40.0, 20.0, 20.0));

	// Format data series
	formatFilledArea(plot, data1, COLOR2);
	formatFilledArea(plot, data2, COLOR1);
	formatLineArea(plot, data3, GraphicsUtils.deriveDarker(COLOR1));

	// Add plot to Swing component
	add(new InteractivePanel(plot));
