Look at the second label when running this test code. Trying to right-align Labels is impossible.

package rightalignedlabels;

import javafx.scene.Scene;
import javafx.scene.control.ContentDisplay;

import javafx.scene.shape.Arc;

public class RightAlignedLabels extends Application {

@Override
public void start(Stage primaryStage) {
VBox vbox = new VBox();
vbox.setAlignment(Pos.CENTER_RIGHT);
vbox.setFillWidth(false);
vbox.setStyle("-fx-border-color: purple; -fx-border-width: 1;");
for (int i = 0; i < 4; i++) {
doLabelBox(i, vbox);
}

Parent group = new Group(vbox);
group.setScaleX(5.0);
group.setScaleY(5.0);

BorderPane root = new BorderPane();
root.setCenter(group);

Scene scene = new Scene(root);

primaryStage.setTitle("Right-aligned Labels look bad");
primaryStage.setScene(scene);
primaryStage.setWidth(550);
primaryStage.setHeight(500);
primaryStage.show();
}


public static void main(String[] args) {
launch(args);
}

private static String alphabet = "cdefghijklmno";//pqrstuvwxyz";
private void doLabelBox(int i, VBox vbox) {
HBox hbox = new HBox();
hbox.setAlignment(Pos.BASELINE_RIGHT);
hbox.setStyle("-fx-border-color: green; -fx-border-width: 1;");
Arc arc = new Arc();
arc.setRadiusX(4);
arc.setRadiusY(4);
arc.setStartAngle(-90);

Label label = new Label("("+alphabet.substring(i)+")", arc);

label.setTranslateX(8);
hbox.getChildren().add(label);
vbox.getChildren().add(hbox);
}
