Class JFreeChart
Tab mode
public class JFreeChart
implements Drawable, TitleChangeListener, PlotChangeListener, Serializable, Cloneable
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 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.

Constructor Detail
JFreeChart
public JFreeChart ( Plot plot )
Creates a new chart based on the supplied plot. The chart will have a legend added automatically, but no title (although you can easily add one later).

Parameters
TypeNameDescription
Plot plot the plot (null not permitted).
Wiki javadoc Use textile entry format.

JFreeChart
public JFreeChart ( String title, Plot plot )
Creates a new chart with the given title and plot. A default font (@link DEFAULT_TITLE_FONT) is used for the title, and the chart will have a legend added automatically.

Note that the ChartFactory class contains a range of static methods that will return ready-made charts, and often this is a more convenient way to create charts than using this constructor.
