How to move Line, Grid and X Ticks together?

Question

The code below plots a XYLineChart: by left mouse click and drag the plotted line can be translated left/right.
package javafxapplication3;
import javafx.application.Application;
import javafx.beans.property.SimpleDoubleProperty;
import javafx.event.EventHandler; 
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.XYChart;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.chart.LineChart;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.BorderPane;
public class GridMove extends Application {
BorderPane pane;
XYChart.Series series1 = new XYChart.Series();
SimpleDoubleProperty rectinitX = new SimpleDoubleProperty();
SimpleDoubleProperty rectX = new SimpleDoubleProperty();
SimpleDoubleProperty rectY = new SimpleDoubleProperty();
@Override
public void start(Stage stage) {
final NumberAxis xAxis = new NumberAxis(1, 12, 1);
final NumberAxis yAxis = new NumberAxis(0.53000, 0.53910, 0.0005);
xAxis.setAnimated(false);
yAxis.setAnimated(false);
yAxis.setTickLabelFormatter(new NumberAxis.DefaultFormatter(yAxis) {
    @Override
    public String toString(Number object) {
        return String.format("%7.5f", object);
final LineChart<Number, Number> lineChart = new LineChart<Number, Number>(xAxis, yAxis);
lineChart.setCreateSymbols(false);
lineChart.setAlternativeRowFillVisible(false);
lineChart.setAnimated(false);
lineChart.setLegendVisible(false);
series1.getData().add(new XYChart.Data(1, 0.53185));
series1.getData().add(new XYChart.Data(2, 0.532235));
series1.getData().add(new XYChart.Data(3, 0.53234));
series1.getData().add(new XYChart.Data(4, 0.538765));
series1.getData().add(new XYChart.Data(5, 0.53442));
series1.getData().add(new XYChart.Data(6, 0.534658));
series1.getData().add(new XYChart.Data(7, 0.53023));
series1.getData().add(new XYChart.Data(8, 0.53001));
series1.getData().add(new XYChart.Data(9, 0.53589));
series1.getData().add(new XYChart.Data(10, 0.53476));
pane = new BorderPane();
pane.setCenter(lineChart);
Scene scene = new Scene(pane, 800, 600);
lineChart.getData().addAll(series1);
stage.setScene(scene);        
scene.setOnMouseClicked(mouseHandler);
scene.setOnMouseDragged(mouseHandler);
scene.setOnMouseEntered(mouseHandler);
scene.setOnMouseExited(mouseHandler);
scene.setOnMouseMoved(mouseHandler);
scene.setOnMousePressed(mouseHandler);
scene.setOnMouseReleased(mouseHandler);
stage.show();
EventHandler<MouseEvent> mouseHandler = new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent mouseEvent) {
    if (mouseEvent.getEventType() == MouseEvent.MOUSE_PRESSED) {            
        rectinitX.set(mouseEvent.getX());
    else if (mouseEvent.getEventType() == MouseEvent.MOUSE_DRAGGED || mouseEvent.getEventType() == MouseEvent.MOUSE_MOVED) {
        LineChart<Number, Number> lineChart = (LineChart<Number, Number>) pane.getCenter();
        NumberAxis xAxis = (NumberAxis) lineChart.getXAxis();
        double Tgap = xAxis.getWidth()/(xAxis.getUpperBound() - xAxis.getLowerBound());
        double newXlower=xAxis.getLowerBound(), newXupper=xAxis.getUpperBound();            
        double Delta=0.3;
        if(mouseEvent.getEventType() == MouseEvent.MOUSE_DRAGGED){
        if(rectinitX.get() < mouseEvent.getX()){   
            newXlower=xAxis.getLowerBound()-Delta;
            newXupper=xAxis.getUpperBound()-Delta;
    else if(rectinitX.get() > mouseEvent.getX()){   
            newXlower=xAxis.getLowerBound()+Delta;
            newXupper=xAxis.getUpperBound()+Delta;
        xAxis.setLowerBound( newXlower );
        xAxis.setUpperBound( newXupper );                       
        rectinitX.set(mouseEvent.getX());                                
    public static void main(String[] args) {
        launch(args);
}My question is: now by moving the Line left/right, Grid and X Ticks does not move: so, how to translate Line, Grid and X Ticks together?
Any help really appreciated!
Thanks
Edit: nobody willing to help?

Some code improvements, now grid and line moves together. It only remains to move X axis ticks along with line and grid, and vertical grid lines are missing outside line range values
