Examples of org.jfree.chart.plot.XYPlot

org.jfree.chart.plot.XYPlot
A general class for plotting data in the form of (x, y) pairs. This plot can use data from any class that implements the {@link XYDataset} interface.
XYPlot makes use of an {@link XYItemRenderer} to draw each pointon the plot. By using different renderers, various chart types can be produced.
The {@link org.jfree.chart.ChartFactory} class contains static methods forcreating pre-configured charts.
