Create Scatter Chart Using JFreeChart

Create Scatter Chart Using JFreeChart explains about creating a simple scatter chart using JFreechart API

A scatter plot (also called a scatterplot, scatter graph, scatter chart, scattergram, or scatter diagram) is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are color-coded, one additional variable can be displayed. The data are displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis.

	JFreeChart chart = ChartFactory.createScatterPlot(chartTitle, "X-Axis", "Y-Axis", createDataset(),
		PlotOrientation.VERTICAL, true, true, true);

	// Changes background color
	XYPlot plot = (XYPlot) chart.getPlot();
	plot.setBackgroundPaint(new Color(255, 228, 196));

	// Adding chart into a chart panel
	ChartPanel chartPanel = new ChartPanel(chart);

	// settind default size
	chartPanel.setPreferredSize(new java.awt.Dimension(500, 270));

	// add to contentPane
