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).
S.N. | Mobile Brands | Sales (UNITS per day) |
---|---|---|
1 | Iphone 5S | 20 |
2 | Samsung Grand | 20 |
3 | MOTO G | 40 |
4 | Nokia Lumia | 10 |
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 :
Car | Speed | User Rating | Millage | Safety |
---|---|---|---|---|
FIAT | 1.0 | 3.0 | 5.0 | 5.o |
AUDI | 5.0 | 6.0 | 10.0 | 4.0 |
FORD | 4.0 | 2.0 | 3.0 | 6.0 |
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:
