Creating a Line Chart
To create a line chart, at a minimum, you must define two axes, create the LineChart object by instantiating the LineChart class, create one or more series of data by using the XYChart.Series class, and assign the data to the chart. Example 32-1 implements these tasks.
Example 32-1 Simple Line Chart
import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.chart.LineChart; import javafx.scene.chart.NumberAxis; import javafx.scene.chart.XYChart; import javafx.stage.Stage; public class LineChartSample extends Application { @Override public void start(Stage stage) { stage.setTitle("Line Chart Sample"); //defining the axes final NumberAxis xAxis = new NumberAxis(); final NumberAxis yAxis = new NumberAxis(); xAxis.setLabel("Number of Month"); //creating the chart final LineChart<Number,Number> lineChart = new LineChart<Number,Number>(xAxis,yAxis); lineChart.setTitle("Stock Monitoring, 2010"); //defining a series XYChart.Series series = new XYChart.Series(); series.setName("My portfolio"); //populating the series with data series.getData().add(new XYChart.Data(1, 23)); series.getData().add(new XYChart.Data(2, 14)); series.getData().add(new XYChart.Data(3, 15)); series.getData().add(new XYChart.Data(4, 24)); series.getData().add(new XYChart.Data(5, 34)); series.getData().add(new XYChart.Data(6, 36)); series.getData().add(new XYChart.Data(7, 22)); series.getData().add(new XYChart.Data(8, 45)); series.getData().add(new XYChart.Data(9, 43)); series.getData().add(new XYChart.Data(10, 17)); series.getData().add(new XYChart.Data(11, 29)); series.getData().add(new XYChart.Data(12, 25)); Scene scene = new Scene(lineChart,800,600); lineChart.getData().add(series); stage.setScene(scene); stage.show(); } public static void main(String[] args) { launch(args); } }
