XY Line Chart
JFreeChart is a free and pure java chart library for
creating professional quality charts.
This requires the libraries
jfreechart-1.0.13.jar and
jcommon-1.0.8.jar
to be in classpath.
The following example shows creating a simple XY line chart.
package com.bethecoder.tutorials.jfree_charts.tests;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartFrame;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.xy.XYDataset;
import org.jfree.data.xy.XYSeries;
import org.jfree.data.xy.XYSeriesCollection;
public class XYLineChart {
public static void main ( String arg []) {
// Prepare the data set
XYSeries xySeries = new XYSeries ( "Number & Square Chart" ) ;
xySeries.add ( 1 , 1 ) ;
xySeries.add ( 2 , 4 ) ;
xySeries.add ( 3 , 9 ) ;
xySeries.add ( 4 , 16 ) ;
xySeries.add ( 5 , 25 ) ;
xySeries.add ( 6 , 36 ) ;
XYDataset xyDataset = new XYSeriesCollection ( xySeries ) ;
//Create the chart
JFreeChart chart = ChartFactory.createXYLineChart (
"Number & Square Chart" , "Number" , "Square" , xyDataset,
PlotOrientation.VERTICAL, true, true, false ) ;
//Render the frame
ChartFrame chartFrame = new ChartFrame ( "XYLine Chart" , chart ) ;
chartFrame.setVisible ( true ) ;
chartFrame.setSize ( 300 , 300 ) ;
}
}
It gives the following output,
