The current version supports bar charts, line charts, pie charts and xy plots (including time series data).JFreeChart coordinates several objects to achieve its aim of being able to draw a chart on a Java 2D graphics device: a list of Title objects (which often includes the chart's legend), a Plot and a Dataset (the plot in turn manages a domain axis and a range axis).You should use a ChartPanel to display a chart in a GUI.The ChartFactory class contains static methods for creating 'ready-made' charts.
