How to draw and copy a line?

Question

I would like to draw a line in a XYLineChart and then copy this line, in order to get this result
[http://s14.postimage.org/4cip47ult/A02519.png]
First left mouse click on point 1, then second mouse click on point 2: my goal is to have now a copy (clone) of this line (same lenght, same slope) that I can place anywhere on the chart, in this example by a third left mouse click on point 3.
How to do this?
Here is the code to draw a line on the chart
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.chart.CategoryAxis;
import javafx.scene.chart.LineChart;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.XYChart;
import javafx.scene.control.Label;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Line;
import javafx.scene.shape.LineTo;
import javafx.scene.shape.MoveTo;
import javafx.scene.shape.Path;
import javafx.stage.Stage;
public class Lines extends Application {
Path path;
public static void main(String[] args) {
    launch(args);
@Override
public void start(Stage stage) {
    final CategoryAxis xAxis = new CategoryAxis();
    final NumberAxis yAxis = new NumberAxis(0.5, 9.5, 0.1);
    yAxis.setTickUnit(1);
    //yAxis.setPrefWidth(35);
    yAxis.setMinorTickCount(10);
    yAxis.setTickLabelFormatter(new NumberAxis.DefaultFormatter(yAxis) {
        @Override
        public String toString(Number object) {
            String label;
            label = String.format("%7.2f", object.floatValue());
            return label;
    final LineChart<String, Number> lineChart = new LineChart<String, Number>(xAxis, yAxis);
    lineChart.setCreateSymbols(false);
    lineChart.setAlternativeRowFillVisible(false);
    lineChart.setLegendVisible(false);
    XYChart.Series series1 = new XYChart.Series();
    series1.getData().add(new XYChart.Data("Jan", 1));
    series1.getData().add(new XYChart.Data("Feb", 4.5));
    series1.getData().add(new XYChart.Data("Mar", 2.5));
    series1.getData().add(new XYChart.Data("Apr", 6.5));
    series1.getData().add(new XYChart.Data("May", 4.5));
    series1.getData().add(new XYChart.Data("Jun", 8.5));
    series1.getData().add(new XYChart.Data("Jul", 6.5));
    BorderPane bp = new BorderPane();
    bp.setCenter(lineChart);
    Scene scene = new Scene(bp, 800, 600);
    lineChart.setAnimated(false);
    lineChart.getData().addAll(series1);
    Lines.MouseHandler mh = new Lines.MouseHandler( bp );
    bp.setOnMouseClicked( mh );
    bp.setOnMouseMoved( mh );
    stage.setScene(scene);
    path = new Path();
    path.setStrokeWidth(1);
    path.setStroke(Color.BLACK);
    scene.setOnMouseDragged(mh);
    scene.setOnMousePressed(mh);
    bp.getChildren().add(path);
    stage.setScene(scene);
    stage.show();
class MouseHandler implements EventHandler< MouseEvent > {
private boolean gotFirst    = false;
private Line    line;
private Pane    pane;
private double  x1, y1, x2, y2;
public MouseHandler( Pane pane ) {
    this.pane = pane;
@Override
public void handle( MouseEvent event ) {
    if( event.getEventType() == MouseEvent.MOUSE_CLICKED ) {
        if( !gotFirst ) {
            x1 = x2 = event.getX();
            y1 = y2 = event.getY();
            line = new Line( x1, y1, x2, y2 );
            pane.getChildren().add( line );
            gotFirst = true;
        else {
            line = null;
            gotFirst = false;
        else {
            if( line != null ) {
                x2 = event.getX();
                y2 = event.getY();
                // update line
                line.setEndX( x2 );
                line.setEndY( y2 );
  }Thanks all.

Sorry for the simplistic question - but where are the photos you are intending to add going to be coming from?
If it is the pictures you take - then it almost seems like you need to first upload them to a cloud service like OneDrive or iCloud and then provide the URL to Google Maps
