it should still fix some issue I want to use 2 objects with one line on each. , Just set a CSS id on each line chart, e.g.
code :
LineChart leftChart = new LineChart(...);

LineChart rightChart = new LineChart(...);
<LineChart id="left" ... >
#left .chart-series-line {-fx-stroke: #ff0099; }

JavaFX LineChart legend style

JavaFX LineChart legend style

hope this fix your issue I ran into this issue as well. Came up with a work-around that detects when the legend items are created so that dynamic styling can be added to them.
I added a ListChangeListener to the legend's "getChildrenUnmodifiable()" ObservableList, which in turn adds a ListChangeListener to each of the legend's children as they get added. From within this listener, we can tell when new items are being added to the legend (or removed). This allow us to then make the dynamic style changes.
code :
for (Node n : lineChart.getChildrenUnmodifiable())
            if (n instanceof Legend)
                final Legend legend = (Legend) n;

                // remove the legend
                legend.getChildrenUnmodifiable().addListener(new ListChangeListener<Object>()
                    public void onChanged(Change<?> arg0)
                        for (Node node : legend.getChildrenUnmodifiable())
                            if (node instanceof Label)
                                final Label label = (Label) node;
                                label.getChildrenUnmodifiable().addListener(new ListChangeListener<Object>()
                                    public void onChanged(Change<?> arg0)
                                        //make style changes here

fixed the issue. Will look into that further HTML example: , You can get rid of text-decoration set on an ancestor using
code :
display: inline-block;
width: 100%;

wish of those help The W3C Markup Validator, when acting as an HTML5 checker, handles this issue according to various drafts such as HTML 5.1 Nightly, which right now says that the style element may appear only inside the head element, except when the scoped attribute is present, in which case it may appear “where flow content is expected, but before any other flow content other than inter-element whitespace and style elements, and not as the child of an element whose content model is transparent”. In your actual example, the element appears after a script element (which is counted as flow content). Changing the order of the elements thus changes the syntax to valid, under the given definition.
Alternatively, you can just wrap the style element in a div element:
code :
<!DOCTYPE html>
<meta charset="UTF-8">
<script type="text/javascript"></script>
  <style scoped></style>

Can I include a JavaFX LineChart in a JavaFX GUI

Can I include a JavaFX LineChart in a JavaFX GUI

Date : March 29 2020, 07:55 AM
I hope this helps . As @James_D said you simply need another container to achieve that. A Pane can contain GUI controls as well as another Pane.
In the example below I put a GridPane with few buttons inside a BorderPane that divides the window into right and left part.
code :
public void start(Stage stage) {
    stage.setTitle("A Title");

    // Root element
    BorderPane root = new BorderPane();

    // GridPane
    GridPane grid = new GridPane();
    grid.setPadding(new Insets(10,10,10,10));
    grid.add(new Button("Button 1"), 0, 0);
    grid.add(new Button("Button 2"), 0, 1);
    grid.add(new Button("Button 3"), 0, 2);

    // Chart
    final NumberAxis xAxis = new NumberAxis();
    final NumberAxis yAxis = new NumberAxis();
    final LineChart<Number, Number> lineChart = new LineChart<>(xAxis, yAxis);
    XYChart.Series series = new XYChart.Series();
    series.getData().add(new XYChart.Data(1, 5));
    series.getData().add(new XYChart.Data(2, 10));


    Scene scene = new Scene(root, 600, 300);
