JavaFX Tutorial - JavaFX Area Chart








The area chart is another type of a two-axis chart.

Creating an Area Chart

To create a area chart use the AreaChart object and create one or more series of data by using the XYChart.Series class, and assign the data to the chart.

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.chart.AreaChart;
import javafx.scene.chart.CategoryAxis;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.XYChart;
import javafx.stage.Stage;
 
public class Main extends Application {
 
    public static void main(String[] args) {
        launch(args);
    }
     
    @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("");
        Group root = new Group();
         
        final CategoryAxis xAxis = new CategoryAxis();
        final NumberAxis yAxis = new NumberAxis();
         
        xAxis.setLabel("Month");
        yAxis.setLabel("Value");
         
        final AreaChart<String,Number> areaChart = new AreaChart<String,Number>(xAxis,yAxis);
 
        areaChart.setTitle("AreaChart");
        XYChart.Series series = new XYChart.Series();
        series.setName("XYChart.Series");
         
        series.getData().add(new XYChart.Data("January", 100));
        series.getData().add(new XYChart.Data("February", 200));
        series.getData().add(new XYChart.Data("March", 50));
         
        areaChart.getData().add(series);
             
        root.getChildren().add(areaChart);
 
        primaryStage.setScene(new Scene(root, 500, 400));
        primaryStage.show();
    }
     
}

The code above generates the following result.
