XYLine Chart

In this section we are providing you an example to create a XYLine Chart.

Description of Program

For creating a XYLine Chart we have to define a set of x,y coordinates by using an object of XYSeries class. Then we add the data in this object that will show in our XYLine chart. After adding the data we make the object of XYDataset of XYSeriesCollection type and add XYSeries object in the dataset.

Description of Code

XYSeries series = new XYSeries("Average Weight");
For defining a set of x,y coordinates we use an object of XYSeries class.

Then we add the data in the XYSeries object by invoking add() method.
series.add(20.0, 50.0);

    XYDataset xyDataset = new XYSeriesCollection(series);
Now we have to create the object of XYDataset type of XYSeriesCollection and add the XYSeries object in the dataset.

    JFreeChart chart = ChartFactory.createXYLineChart("XYLine Chart using JFreeChart", "Age", "Weight", xyDataset, PlotOrientation.VERTICAL, true, true, false);
After creating the dataset we create the XYLine Chart by invoking the createXYLineChart() method. This method is a static method of ChartFactory class and its returns the object of JFreeChart type.This method syntax is:

Public static JFreeChart createXYLineChart(java.lang.String title, java.lang.String xAxisLabel, java.lang.String yAxisLabel, XYDataset dataset, PlotOrientation orientation, boolean legend, boolean tooltips, boolean urls)

    ChartFrame frame1=new ChartFrame("XYLine Chart",chart);
After this we create the object of ChartFrame. It used to display a chart.

Here is the code of the Program :


import org.jfree.chart.*;

import org.jfree.chart.plot.PlotOrientation;

import org.jfree.data.category.DefaultCategoryDataset;

import org.jfree.data.general.DefaultPieDataset;

import org.jfree.data.xy.*;

import org.jfree.data.*;



public class xyLine{

public static void main(String arg[]){

  XYSeries series = new XYSeries("Average Weight");

  series.add(20.0, 20.0);

  series.add(40.0, 25.0);

  series.add(55.0, 50.0);

  series.add(70.0, 65.0);

  XYDataset xyDataset = new XYSeriesCollection(series);

  JFreeChart chart = ChartFactory.createXYLineChart

  ("XYLine Chart using JFreeChart", "Age", "Weight",

 xyDataset, PlotOrientation.VERTICAL, true, true, false);

  ChartFrame frame1=new ChartFrame("XYLine Chart",chart);

  frame1.setVisible(true);

  frame1.setSize(300,300);

  }

}
