2 Grafik / Chart Dengan JFreeChart Pada Java

Hal yang pertama kali dilakukan yaitu membuat sebuah class yang berfungsi untuk membuat chart/grafik
Pada kali ini saya akan memberi nama class tersebut class DualAxisDemo1


package demo;

import java.awt.Color;
import java.awt.Dimension;
import javax.swing.JPanel;
import org.jfree.chart.*;
import org.jfree.chart.axis.*;
import org.jfree.chart.block.*;
import org.jfree.chart.labels.StandardCategoryToolTipGenerator;
import org.jfree.chart.plot.*;
import org.jfree.chart.renderer.category.LineAndShapeRenderer;
import org.jfree.chart.title.CompositeTitle;
import org.jfree.chart.title.LegendTitle;
import org.jfree.data.category.CategoryDataset;
import org.jfree.data.category.DefaultCategoryDataset;
import org.jfree.ui.*;

public class DualAxisDemo1 extends ApplicationFrame
{

public DualAxisDemo1(String s)
{
super(s);
JFreeChart jfreechart = createChart();
ChartPanel chartpanel = new ChartPanel(jfreechart);
chartpanel.setPreferredSize(new Dimension(500, 270));
setContentPane(chartpanel);
}

private static CategoryDataset createDataset1()
{
String s = "S1";
String s1 = "S2";
String s2 = "S3";
String s3 = "Category 1";
String s4 = "Category 2";
String s5 = "Category 3";
String s6 = "Category 4";
String s7 = "Category 5";
String s8 = "Category 6";
String s9 = "Category 7";
String s10 = "Category 8";
DefaultCategoryDataset defaultcategorydataset = new DefaultCategoryDataset();
defaultcategorydataset.addValue(1, s, s3);
defaultcategorydataset.addValue(2, s, s4);
defaultcategorydataset.addValue(3, s, s5);
defaultcategorydataset.addValue(4, s, s6);
defaultcategorydataset.addValue(5D, s, s7);
defaultcategorydataset.addValue(7D, s, s8);
defaultcategorydataset.addValue(7D, s, s9);
defaultcategorydataset.addValue(8D, s, s10);
defaultcategorydataset.addValue(5D, s1, s3);
defaultcategorydataset.addValue(7D, s1, s4);
defaultcategorydataset.addValue(6D, s1, s5);
defaultcategorydataset.addValue(8D, s1, s6);
defaultcategorydataset.addValue(4D, s1, s7);
defaultcategorydataset.addValue(4D, s1, s8);
defaultcategorydataset.addValue(2D, s1, s9);
defaultcategorydataset.addValue(1.0D, s1, s10);
defaultcategorydataset.addValue(4D, s2, s3);
defaultcategorydataset.addValue(3D, s2, s4);
defaultcategorydataset.addValue(2D, s2, s5);
defaultcategorydataset.addValue(3D, s2, s6);
defaultcategorydataset.addValue(6D, s2, s7);
defaultcategorydataset.addValue(3D, s2, s8);
defaultcategorydataset.addValue(4D, s2, s9);
defaultcategorydataset.addValue(3D, s2, s10);
return defaultcategorydataset;
}

private static CategoryDataset createDataset2()
{
String s = "S4";
String s1 = "Category 1";
String s2 = "Category 2";
String s3 = "Category 3";
String s4 = "Category 4";
String s5 = "Category 5";
String s6 = "Category 6";
String s7 = "Category 7";
String s8 = "Category 8";
DefaultCategoryDataset defaultcategorydataset = new DefaultCategoryDataset();
defaultcategorydataset.addValue(15D, s, s1);
defaultcategorydataset.addValue(24D, s, s2);
defaultcategorydataset.addValue(31D, s, s3);
defaultcategorydataset.addValue(25D, s, s4);
defaultcategorydataset.addValue(56D, s, s5);
defaultcategorydataset.addValue(37D, s, s6);
defaultcategorydataset.addValue(77D, s, s7);
defaultcategorydataset.addValue(18D, s, s8);
return defaultcategorydataset;
}

private static JFreeChart createChart()
{
JFreeChart jfreechart = ChartFactory.createBarChart("Dual Axis Chart", "Category", "Value", createDataset1(), PlotOrientation.VERTICAL, false, true, false);
jfreechart.setBackgroundPaint(Color.white);
CategoryPlot categoryplot = (CategoryPlot)jfreechart.getPlot();
categoryplot.setBackgroundPaint(new Color(238, 238, 255));
categoryplot.setDomainAxisLocation(AxisLocation.BOTTOM_OR_RIGHT);
CategoryDataset categorydataset = createDataset2();
categoryplot.setDataset(1, categorydataset);
categoryplot.mapDatasetToRangeAxis(1, 1);
CategoryAxis categoryaxis = categoryplot.getDomainAxis();
categoryaxis.setCategoryLabelPositions(CategoryLabelPositions.DOWN_45);
NumberAxis numberaxis = new NumberAxis("Secondary");
categoryplot.setRangeAxis(1, numberaxis);
LineAndShapeRenderer lineandshaperenderer = new LineAndShapeRenderer();
lineandshaperenderer.setToolTipGenerator(new StandardCategoryToolTipGenerator());
categoryplot.setRenderer(1, lineandshaperenderer);
categoryplot.setDatasetRenderingOrder(DatasetRenderingOrder.FORWARD);
LegendTitle legendtitle = new LegendTitle(categoryplot.getRenderer(0));
legendtitle.setMargin(new RectangleInsets(2D, 2D, 2D, 2D));
legendtitle.setBorder(new BlockBorder());
LegendTitle legendtitle1 = new LegendTitle(categoryplot.getRenderer(1));
legendtitle1.setMargin(new RectangleInsets(2D, 2D, 2D, 2D));
legendtitle1.setBorder(new BlockBorder());
BlockContainer blockcontainer = new BlockContainer(new BorderArrangement());
blockcontainer.add(legendtitle, RectangleEdge.LEFT);
blockcontainer.add(legendtitle1, RectangleEdge.RIGHT);
blockcontainer.add(new EmptyBlock(2000D, 0.0D));
CompositeTitle compositetitle = new CompositeTitle(blockcontainer);
compositetitle.setPosition(RectangleEdge.BOTTOM);
jfreechart.addSubtitle(compositetitle);
return jfreechart;
}

public static JPanel createDemoPanel()
{
JFreeChart jfreechart = createChart();
return new ChartPanel(jfreechart);
}
}

Selanjutnya yaitu tinggal menjalankannya melalui class main

package demo;

import org.jfree.ui.RefineryUtilities;
public class Main {
public static void main(String args[])
{
DualAxisDemo1 dualaxisdemo1 = new DualAxisDemo1("Dual Axis Demo 1");
dualaxisdemo1.pack();
RefineryUtilities.centerFrameOnScreen(dualaxisdemo1);
dualaxisdemo1.setVisible(true);
}
}

Hasilnya akan seperti ini :


Selamat Mencoba :D
