JavaFX Pie Chart

In the JavaFX application, in order to create Pie Chart, the PieChart class is used. The Pie Chart allows us to plot data along with the sectors of the circle. All methods needed for this purpose are present in the javafx.scene.chart.PieChart class.

The constructor of Pie Chart:

1. PieChart():

It is used to create the empty Pie Chart.

2. PieChart(ObseravableList newlist):

It is used to create Pie Chart with specified new data.

Charts in JavaFX applications- Pie Chart showing constituents of air gases:

Example:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.chart.PieChart;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;


public class ChartUI extends Application {  


    @Override  
    public void start(Stage primaryStage) throws Exception 
    {  
      PieChart pieChart = new PieChart();


          PieChart.Data slice1 = new PieChart.Data("Oxygen ", 20);
          PieChart.Data slice2 = new PieChart.Data("Other Gases"  , 1);
          PieChart.Data slice3 = new PieChart.Data("Nitrogen" , 79);


          pieChart.getData().add(slice1);
          pieChart.getData().add(slice2);
          pieChart.getData().add(slice3);


          VBox vbox = new VBox(pieChart);


          Scene scene = new Scene(vbox, 400, 200);


          primaryStage.setScene(scene);  
           primaryStage.setTitle(" JavaFX Chart - Pie Chart Example");  
           primaryStage.show();  
        }
    public static void main(String[] args) {
        Application.launch(args);
    }
}

Output:

In order to create the Pie Chart in JavaFX, we have to import all the required libraries such as javafx.application.Application, javafx.stage.Stage, javafx.scene.Scene, javafx.scene.chart.PieChart, javafx.scene.layout.VBox.

Then we have created one class named ChartUI extending the Application class. Also, we have to override the start method to provide implementation details. This method creates an object of Stage as primaryStage. For the container to hold a Pie Chart with constituents of air in different sectors, a PieChart object is created which is then passed to the Scene class object.

Pie Chart is created with the help of its constructor. Data for the pie chart is added using PieChart.Data is then added to the pie chart object.

The stage is prepared, the title is set and the show() method is called to display output. In order to run the application, the launch(args) method is invoked. In output Frame like container is displayed with the title, " JavaFX Chart – Pie Chart Example". Also, it displays a pie chart with different air constituents like Oxygen, Nitrogen, Other gases mentioned in different sectors.

Charts in JavaFX applications – Pie Chart showing measure of different language:

Example:

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.geometry.Side;
import javafx.scene.Scene;
import javafx.scene.chart.PieChart;
import javafx.scene.chart.PieChart.Data;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;


public class ChartUI extends Application {  


    @Override  
    public void start(Stage primaryStage) throws Exception 
    {  
      PieChart chart = new PieChart();  
      
      chart.setData(getChartData());  
      chart.setLegendSide(Side.LEFT);  
      chart.setTitle(" Indian Languages ");  
      chart.setClockwise(false);  
          
        StackPane root = new StackPane();  
          
        root.getChildren().add(chart);  
          
        Scene scene = new Scene(root,800,600);  
        primaryStage.setScene(scene);  
        primaryStage.setTitle("JavaFX Chart - Pie Chart Example");  
        primaryStage.show();  
          
    }  
      
    private ObservableList<Data> getChartData() {  
        ObservableList<Data> list = FXCollections.observableArrayList();  
        list.addAll(new PieChart.Data("Marathi", 30.8),  
                new PieChart.Data("Hindi", 11.8),  
                new PieChart.Data("English", 10.8),  
                new PieChart.Data("Tamil", 11.6),  
                new PieChart.Data("Telgu", 7.2),  
                new PieChart.Data("Gujarathi", 10.7),  
                new PieChart.Data("Bengali", 5.2) 
    );  
        return list;  
    }  
}

In order to create the Pie Chart in JavaFX, we have to import all the required libraries such as javafx.application.Application, javafx.stage.Stage, javafx.scene.Scene, javafx.scene.chart.PieChart, javafx.scene.layout.VBox, javafx.collections.FXCollections, javafx.collections.ObservableList, javafx.geometry.Side.

Then we have created one class named ChartUI extending the Application class. Also, we have to override the start method to provide implementation details. This method creates an object of Stage as primaryStage. For the container to hold Pie Chart with Indian languages in different sectors, a PieChart object is created which is then passed to the Scene class object.

Pie Chart is created with the help of its constructor. Data for the pie chart is added using the chart.setData() method. Also setTitle() and setLegendSide() method is used with pie chart.

The stage is prepared, the title is set and the show() method is called to display output. In order to run the application, the launch(args) method is invoked. In output Frame like container is displayed with the title, " JavaFX Chart – Pie Chart Example". Also, it displays a pie chart with different Indian languages in different sectors of the pie chart.
