How to remove the legend of 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.
Making the legend invisible
The PieChart class has a property named legendVisible (inherited from the class Chart). It is of type boolean and, you can set the value to it using the setLegendVisible() method.
By default, the value of the legendVisible property is true, if you set it to false, the legend will be invisible.
Example
import javafx.application.Application; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.scene.Scene; import javafx.stage.Stage; import javafx.scene.chart.PieChart; import javafx.scene.layout.StackPane; public class PieChartExample 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); //Making the legend invisible pieChart.setLegendVisible(false); //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); } }
