How to change the position of the legend in a PieChart in JavaFX?
In the pie chart, we represent the data values as slices of a circle. Each slice is differentiated from other (typically by color). In JavaFX, you can create a pie chart by instantiating the javafx.scene.chart.PieChart class.
By default, a JavaFX pie chart contains labels of the slices and a legend − a bar with colors specifying the category represented by each color.
Changing the position of the Legend −
The PieChart class has a property named legendSide (inherited from the Chart class). This specifies the position of the legend in the chart (left, right, top-bottom). You can set the value to this property using the setLegendSide() method. This method accepts one of the following values as a parameter −
Side.BOTTOM
Side.TOP
Side.LEFT
Side.RIGHT
You can change the position of the legend in a chart, by invoking the setLegendSide() method by passing the appropriate value as a parameter.
Example
import javafx.application.Application; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.geometry.Side; import javafx.scene.Scene; import javafx.stage.Stage; import javafx.scene.chart.PieChart; import javafx.scene.layout.StackPane; public class PieChart_LegendPosition extends Application { @Override public void start(Stage stage) { //Creating a Pie chart PieChart pieChart = new PieChart(); //Setting data ObservableList data = FXCollections.observableArrayList( new PieChart.Data("Work", 10), new PieChart.Data("Chores", 2), new PieChart.Data("Sleep", 8), new PieChart.Data("Others", 4)); pieChart.setData(data); //Setting the legend on the left side of the chart pieChart.setLegendSide(Side.LEFT); //Creating a stack pane to hold the pie chart StackPane pane = new StackPane(pieChart); pane.setStyle("-fx-background-color: BEIGE"); //Setting the Scene Scene scene = new Scene(pane, 595, 300); stage.setTitle("Pie Chart"); stage.setScene(scene); stage.show(); } public static void main(String args[]){ launch(args); } }
