public NumberAxis(double lowerBound, double upperBound, double tickUnit)
Create a non-auto-ranging NumberAxis with the given upper bound, lower bound and tick unit.
Parameters:
- lowerBound - The lower bound for this axis, ie min plottable value
- upperBound - The upper bound for this axis, ie max plottable value
- tickUnit - The tick unit, ie space between tickmarks
Example:
package javafx21; 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; /** * * @web http://java-buddy.blogspot.com/ */ public class Charts extends Application { /** * @param args the command line arguments */ public static void main(String[] args) { launch(args); } @Override public void start(Stage primaryStage) { primaryStage.setTitle("java-buddy.blogspot.com"); Group root = new Group(); //final NumberAxis xAxis = new NumberAxis(); //Use 3 parameter constructor to define the min, max and space of the axis final NumberAxis xAxis = new NumberAxis(1, 12, 1); final NumberAxis yAxis = new NumberAxis(); final StackedAreaChart<Number,Number> stackedAreaChart = new StackedAreaChart<>(xAxis,yAxis); final XYChart.Series<Number,Number> series1 = new XYChart.Series<>(); xAxis.setLabel("Month"); yAxis.setLabel("Value"); stackedAreaChart.setTitle("StackedAreaChart"); //Series 1 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(3, 50)); series1.getData().add(new XYChart.Data(4, 75)); series1.getData().add(new XYChart.Data(5, 110)); series1.getData().add(new XYChart.Data(6, 300)); series1.getData().add(new XYChart.Data(7, 111)); series1.getData().add(new XYChart.Data(8, 30)); series1.getData().add(new XYChart.Data(9, 75)); series1.getData().add(new XYChart.Data(10, 55)); series1.getData().add(new XYChart.Data(11, 225)); series1.getData().add(new XYChart.Data(12, 99)); //Series 2 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(3, 260)); series2.getData().add(new XYChart.Data(4, 100)); //series2.getData().add(new XYChart.Data(5, 100)); series2.getData().add(new XYChart.Data(6, 100)); series2.getData().add(new XYChart.Data(7, 0)); //series2.getData().add(new XYChart.Data(8, 0)); series2.getData().add(new XYChart.Data(9, 0)); series2.getData().add(new XYChart.Data(10, 100)); //series2.getData().add(new XYChart.Data(11, 150)); series2.getData().add(new XYChart.Data(12, 200)); // stackedAreaChart.getData().addAll(series1, series2); root.getChildren().addAll(stackedAreaChart); primaryStage.setScene(new Scene(root, 500, 400)); primaryStage.show(); } }
