JFreeChart – 3D Pie/Bar Chart

The 3D charts are the ones, which appear in a three-dimensional format. You can use these charts to provide better display and clear information. A 3D Pie chart is same as the pie chart additionally with a nice 3D effect. A 3D effect can achieved by adding a little extra code which will take care of creating 3D effect in a pie chart.

3D Pie chart

Consider the following example to depict mobile sale with the help of a 3D pie chart. Following is a list of different mobile brands and their sale (units per day).

Following is the code to create 3D Pie Chart from the above given information. This code helps you embed a pie chart in any AWT based application.

import java.io.*; 
import org.jfree.chart.ChartFactory; 
import org.jfree.chart.JFreeChart; 
import org.jfree.chart.plot.PiePlot3D; 
import org.jfree.data.general.DefaultPieDataset; 
import org.jfree.chart.ChartUtilities;

public class PieChart3D 
{
   public static void main( String[ ] args )throws Exception 
   {
      DefaultPieDataset dataset = new DefaultPieDataset( );             
      dataset.setValue( "IPhone 5s" , new Double( 20 ) );             
      dataset.setValue( "SamSung Grand" , new Double( 20 ) );             
      dataset.setValue( "MotoG" , new Double( 40 ) );             
      dataset.setValue( "Nokia Lumia" , new Double( 10 ) ); 

      JFreeChart chart = ChartFactory.createPieChart3D( 
         "Mobile Sales" ,  // chart title                   
         dataset ,         // data 
         true ,            // include legend                   
         true, 
         false);

      final PiePlot3D plot = ( PiePlot3D ) chart.getPlot( );             
      plot.setStartAngle( 270 );             
      plot.setForegroundAlpha( 0.60f );             
      plot.setInteriorGap( 0.02 );             
      int width = 640; /* Width of the image */             
      int height = 480; /* Height of the image */                             
      File pieChart3D = new File( "pie_Chart3D.jpeg" );                           
      ChartUtilities.saveChartAsJPEG( pieChart3D , chart , width , height );   
   }
}

Let us keep the above Java code in PieChart3D.java file, and then compile and run it from command prompt as follows :

$javac PieChart3D.java 
$java PieChart3D

If everything is fine , it will compile and run to create JPEG image file named PieChart3D.jpeg having the following 3D Pie Chart :

3D Bar Chart

A 3D Bar chart is same as the bar chart additionally with a nice 3D effect. A 3D effect can achieved by adding a little extra code which will take care of creating 3D effect in a bar chart. Consider the following example that depicts various car statistics with the help of a 3D bar chart. Following is a list of car brands along with their different characteristics, which we will show using a bar chart :

Following code creates 3D Bar Chart from the above given information. This code helps you embed a bar chart in any AWT based application.

import java.io.*; 
import org.jfree.chart.ChartFactory; 
import org.jfree.chart.JFreeChart; 
import org.jfree.chart.plot.PlotOrientation; 
import org.jfree.data.category.DefaultCategoryDataset; 
import org.jfree.chart.ChartUtilities; 

public class BarChart3D
{
   public static void main( String[ ] args )throws Exception 
   {
      final String fait = "FAIT";              
      final String audi = "AUDI";              
      final String ford = "FORD";              
      final String speed = "Speed";              
      final String popular = "Popular";              
      final String mailage = "Mailage";              
      final String userrating = "User Rating";              
      final String safty = "safty";        
      final DefaultCategoryDataset dataset = new DefaultCategoryDataset( ); 

      dataset.addValue( 1.0 , fait , speed );              
      dataset.addValue( 4.0 , fait , popular );              
      dataset.addValue( 3.0 , fait , userrating );              
      dataset.addValue( 5.0 , fait , mailage );              
      dataset.addValue( 5.0 , fait , safty );              
      dataset.addValue( 5.0 , audi , speed );              
      dataset.addValue( 7.0 , audi , popular );              
      dataset.addValue( 6.0 , audi , userrating );              
      dataset.addValue( 10.0 , audi , mailage );              
      dataset.addValue( 4.0 , audi , safty ); 
      dataset.addValue( 4.0 , ford , speed );              
      dataset.addValue( 3.0 , ford , popular );              
      dataset.addValue( 2.0 , ford , userrating );              
      dataset.addValue( 3.0 , ford , mailage );              
      dataset.addValue( 6.0 , ford , safty );                 
      JFreeChart barChart = ChartFactory.createBarChart3D(
         "Car Usage Statistics",             
         "Category",             
         "Score",             
         dataset,            
         PlotOrientation.VERTICAL,             
         true, true, false);
         
      int width = 640; /* Width of the image */              
      int height = 480; /* Height of the image */                              
      File barChart3D = new File( "barChart3D.jpeg" );                            
      ChartUtilities.saveChartAsJPEG( barChart3D, barChart, width, height);
   }
}

Let us keep the above Java code in BarChart3D.java file, and then compile and run it from command prompt as follows :

$javac BarChart3D.java 
$java BarChart3

If everything is fine with your environment, it will compile and run to create JPEG image file BarChart3D.jpeg having the following 3D Bar Chart:
