• AreaChart X Axis and Y Axis
• Creating an AreaChart
• AreaChart Data Series
• Adding an AreaChart to the Scene Graph

The JavaFX AreaChart can draw area charts inside your JavaFX applications. An area chart is a line chart where the area below the lines are painted with color. The JavaFX AreaChart component is represented by the class javafx.scene.chart.AreaChart .

AreaChart X Axis and Y Axis

A JavaFX AreaChart draws an area chart. An area chart is a two-dimensional graph, meaning the graph has an X axis and a Y axis. Area charts typically have two numerical axes. A numerical axis is represented by the JavaFX class javafx.scene.chart.NumberAxis .

You need to define the X axis and Y axis used by a AreaChart. Here is an example of creating two JavaFX NumberAxis instances:

NumberAxis xAxis = new NumberAxis();
xAxis.setLabel("No of employees");

NumberAxis yAxis = new NumberAxis();
yAxis.setLabel("Revenue per employee");

Creating an AreaChart

You create a JavaFX AreaChart component by creating an instance of the AreaChart class. You need to pass an X axis and Y axis to the AreaChart constructor. Here is a JavaFX AreaChart instantiation example:

NumberAxis xAxis = new NumberAxis();
xAxis.setLabel("No of employees");

NumberAxis yAxis = new NumberAxis();
yAxis.setLabel("Revenue per employee");

AreaChart areaChart = new AreaChart(xAxis, yAxis);

AreaChart Data Series

To get a JavaFX AreaChart component to display anything, you must provide it with a data series. A data series is a list of data points. Each data point contains an X value and a Y value. Here is an example of creating a data series and adding it to a AreaChart component:

XYChart.Series dataSeries1 = new XYChart.Series();
dataSeries1.setName("2014");

dataSeries1.getData().add(new XYChart.Data( 1, 567));
dataSeries1.getData().add(new XYChart.Data( 5, 612));
dataSeries1.getData().add(new XYChart.Data(10, 800));
dataSeries1.getData().add(new XYChart.Data(20, 780));
dataSeries1.getData().add(new XYChart.Data(40, 810));
dataSeries1.getData().add(new XYChart.Data(80, 850));

areaChart.getData().add(dataSeries1);

First an XYChart.Series instance is created and given a name. Second, 6 XYChart.Data instances are added to the XYChart.Series object. Third, the XYChart.Series object is added to a AreaChart object.

It is possible to add multiple data series to the AreaChart . Just repeat the above code for additional data series.

Adding an AreaChart to the Scene Graph

To make a JavaFX AreaChart visible you must add it to the JavaFX scene graph. This means adding the AreaChart to a Scene object or add the AreaChart to a layout component which is added to a Scene object.

Here is an example that adds an AreaChart to the JavaFX scene graph:

package com.jenkov.javafx.charts;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.chart.AreaChart;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.XYChart;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class AreaChartExperiments extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        primaryStage.setTitle("AreaChart Experiments");

        NumberAxis xAxis = new NumberAxis();
        xAxis.setLabel("No of employees");

        NumberAxis yAxis = new NumberAxis();
        yAxis.setLabel("Revenue per employee");

        AreaChart areaChart = new AreaChart(xAxis, yAxis);

        XYChart.Series dataSeries1 = new XYChart.Series();
        dataSeries1.setName("2014");

        dataSeries1.getData().add(new XYChart.Data( 1, 567));
        dataSeries1.getData().add(new XYChart.Data( 5, 612));
        dataSeries1.getData().add(new XYChart.Data(10, 800));
        dataSeries1.getData().add(new XYChart.Data(20, 780));
        dataSeries1.getData().add(new XYChart.Data(40, 810));
        dataSeries1.getData().add(new XYChart.Data(80, 850));

        areaChart.getData().add(dataSeries1);

        VBox vbox = new VBox(areaChart);

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

        primaryStage.setScene(scene);
        primaryStage.setHeight(300);
        primaryStage.setWidth(1200);

        primaryStage.show();
    }


    public static void main(String[] args) {
        Application.launch(args);
    }
}

The application resulting from running this application would look similar to this:
