polygons not showing on screen

[mike Vigor]

So this is my very first attempt at a gui..
I need to first have a grid which I'm calling a ship populated with hexagons...
I've written this code from looking at the tutorials but upon clicking run the polygons don't show..
don't mind the class nesting...a necessary evil for now to help me understand the concepts of gui...

public class Main extends Application
{   
	private static final int hexSize = 50;
	private static final int rootHeight = 800;
	private static final int rootWidth = 800;
	private static final Integer yCoord = 14;
	private static final Integer xCoord = 26;
	private Sector ship [][]= new Sector [14][26];
	public Scene scene ;
	
	private Parent createContent()
	{
		Pane root = new Pane();
		root.setPrefSize(rootHeight,rootWidth);
		for(int y = 0; y < yCoord; y++)
		{
			for(int x = 0; x < xCoord; x++)
			{
				Sector sector = new Sector(yCoord.toString().concat(xCoord.toString()));
				ship[y][x]= sector;
				root.getChildren().add(sector);
			}
		}
		
		for(int y = 0; y < yCoord; y++)
		{
			for(int x = 0; x < xCoord; x++)
			{
				Sector sector = ship[y][x];
				sector.text.setText(yCoord.toString().concat(xCoord.toString()));
			}
		}
		
	    return root;
	}
	
	public class Sector extends StackPane
	{
	 private Polygon Hex;
	 private Text text = new Text ();
	 
	 public Sector(String name)
	 {   
		 double ax = 0.0, ay=0.0, bx= 20.0, by = 40.0, cx = 60.0,cy = 40.0;
		 double dx= 80.0, dy = 0.0, ex =60.0, ey = -40.0, fx = 20.0, fy =-40.0;
		 
		 Hex = new Polygon();
		 Hex.getPoints().addAll(new Double[]{
				 0.0, 0.0,
				 20.0, 40.0,
				 60.0, 40.0,
				 80.0, 0.0,
				 60.0, -40.0,
				 20.0, -40.0});
		 Hex.setStroke(Color.RED);
		 text.setText(name);
		 text.setFont(Font.font(12));
		 text.setVisible(true);
		 text.setFill(Color.BLACK);
		 
		 getChildren().addAll(Hex, text);
		 
		 setTranslateX(ax * hexSize); setTranslateY(ay * hexSize); setTranslateY(bx * hexSize); setTranslateY(by * hexSize);
		 setTranslateX(cx * hexSize); setTranslateY(cy * hexSize); setTranslateY(dx * hexSize); setTranslateY(dy * hexSize);
		 setTranslateX(ex * hexSize); setTranslateY(ey * hexSize); setTranslateY(fx * hexSize); setTranslateY(fy * hexSize);
		 
	}
  }
	
	@Override
	public void start(Stage stage) 
	{
		scene = new Scene(createContent());
		stage.setScene(scene);
		stage.show();
		
	}
	
	public static void main(String[] args) {launch(args);	}
}

Kindly read this.

Can you tell us what these lines are meant to do?

         setTranslateX(ax * hexSize); setTranslateY(ay * hexSize); setTranslateY(bx * hexSize); setTranslateY(by * hexSize);
         setTranslateX(cx * hexSize); setTranslateY(cy * hexSize); setTranslateY(dx * hexSize); setTranslateY(dy * hexSize);
         setTranslateX(ex * hexSize); setTranslateY(ey * hexSize); setTranslateY(fx * hexSize); setTranslateY(fy * hexSize);

If I remove them, I get a hex in the top left corner of the screen.
