JavaFX教程 - JavaFX区域图
区域图是另一种类型的双轴图表。
import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.chart.NumberAxis; import javafx.scene.chart.StackedAreaChart; 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) { Group root = new Group(); final NumberAxis xAxis = new NumberAxis(1, 12, 1); final NumberAxis yAxis = new NumberAxis(); final StackedAreaChart<Number,Number> stackedAreaChart = new StackedAreaChart<Number,Number>(xAxis,yAxis); final XYChart.Series<Number,Number> series1 = new XYChart.Series<Number,Number>(); xAxis.setLabel("Month"); yAxis.setLabel("Value"); stackedAreaChart.setTitle("StackedAreaChart"); series1.setName("XYChart.Series 1"); series1.getData().add(new XYChart.Data(1, 100)); series1.getData().add(new XYChart.Data(2, 200)); series1.getData().add(new XYChart.Data(10, 150)); XYChart.Series<Number,Number> series2 = new XYChart.Series(); series2.setName("XYChart.Series 2"); series2.getData().add(new XYChart.Data(1, 50)); series2.getData().add(new XYChart.Data(2, 200)); series2.getData().add(new XYChart.Data(10, 260)); stackedAreaChart.getData().addAll(series1, series2); root.getChildren().addAll(stackedAreaChart); primaryStage.setScene(new Scene(root, 500, 400)); primaryStage.show(); } }

创建区域图
要创建区域图,请使用AreaChart对象和使用XYChart.Series类创建一个或多个数据系列,并将数据分配给图表。
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(); } }
