    public class XYPlot

extends Plot
implements ValueAxisPlot, Zoomable, RendererChangeListener, java.lang.Cloneable, org.jfree.util.PublicCloneable, java.io.Serializable

A general class for plotting data in the form of (x, y) pairs. This plot can use data from any class that implements the `XYDataset` interface.

`XYPlot` makes use of an `XYItemRenderer` to draw each point on the plot. By using different renderers, various chart types can be produced.

The `ChartFactory` class contains static methods for creating pre-configured charts.
