Examples of JFreeChart

org.jfree.chart.JFreeChart
A chart class implemented using the Java 2D APIs. 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 {@link Title} objects(which often includes the chart's legend), a {@link Plot} and a{@link org.jfree.data.general.Dataset} (the plot in turn manages adomain axis and a range axis).
You should use a {@link ChartPanel} to display a chart in a GUI.
The {@link ChartFactory} class contains static methods for creating'ready-made' charts. @see ChartPanel @see ChartFactory @see Title @see Plot
