JavaFX charts, snapshots

I'm trying to get a snapshot of my java popup The Java window looks like:

But the snapshot looks like: http://www.directupload.net/file/d/3616/cx47ga2o_png.htm

I'm sorry for these links, but I'm not allowed to post pictures yet

Therefore, the automatic range is missing on the Y axis and the date is missing on the X axis Why not make my snapshot function global? Do you have any suggestions / ideas on how to solve this problem? I would appreciate any help

Code snapshot function:

public void saveAsPng(Scene scene) {
    WritableImage image = scene.snapshot(null);
    File file = new File("chart.png");
    try {
        ImageIO.write(SwingFXUtils.fromFXImage(image,null),"png",file);
    } catch (IOException ex) {
        Logger.getLogger(Server_Application.class.getName()).log(Level.SEVERE,null,ex);
    }
}

Call function:

@Override
public void start(Stage stage) throws Exception {
...
Parent root = FXMLLoader.load(getClass().getResource("MainPicture.fxml"));
Scene scene = new Scene(root);              
stage.setScene(scene);
stage.show();
Server_Application.serverApp.saveAsPng(scene);
...
}

Solution

I got the solution:

You must deactivate the animation of the chart:

lineChart.setAnimated(false);
