How to clear text added in a javafx barchart?

Question

I add some text at the top of bars (the value of each bar). It\'s working but the problem is I want to remove this text each time I update the chart. In fact, text stays aft

I have found only one solution, which is to clear every parentNode of each Data when you receive an update. You'll reconstruct the whole series then. As follow, it works but I didn't check the performance. On my environment it's pretty fast :

ObservableList> allSeries = yourBarChart.getData();
    if (updateReceived) {
        for (XYChart.Series series : allSeries) {
            for (XYChart.Data data : series.getData()) {
                Node node = data.getNode();
                Parent parent = node.parentProperty().get();
                if (parent != null && parent instanceof Group) {
                    Group group = (Group) parent;
                    group.getChildren().clear();
                }
            }
        }
        allSeries.clear();
    }
