Usage

From source file:Main.java

public static void addMarker(final XYChart<?, ?> chart, final StackPane chartWrap) {
    final Line valueMarker = new Line();
    final Node chartArea = chart.lookup(".chart-plot-background");

    chartArea.setOnMouseMoved(new EventHandler<MouseEvent>() {
        @Override//from  ww w  .j a  v a2  s .c o  m
        public void handle(MouseEvent event) {
            Point2D scenePoint = chart.localToScene(event.getSceneX(), event.getSceneY());
            Point2D position = chartWrap.sceneToLocal(scenePoint.getX(), scenePoint.getY());

            Bounds chartAreaBounds = chartArea.localToScene(chartArea.getBoundsInLocal());
            valueMarker.setStartY(0);
            valueMarker.setEndY(chartWrap.sceneToLocal(chartAreaBounds).getMaxY()
                    - chartWrap.sceneToLocal(chartAreaBounds).getMinY());

            valueMarker.setStartX(0);
            valueMarker.setEndX(0);
            valueMarker.setTranslateX(position.getX() - chartWrap.getWidth() / 2);

            double ydelta = chartArea.localToScene(0, 0).getY() - chartWrap.localToScene(0, 0).getY();
            valueMarker.setTranslateY(-ydelta * 2);
        }
    });

    chartWrap.getChildren().add(valueMarker);
}
