how to add 3 legend for a single series barchart?? JAVAFX - css

Question

Here is my code to generate 10 bars of different colors. I want to add legend respectively but it only shows yellow legend i can change its color but i want 3 legend.
I think it shows only 1 color because there is only 1 series. Is it possible to add more than 1 legend for a single series?
output:
or if i can add this image as legend to the middle left of my chart
i need how to display image in bar chart or how to create 3 different labels for a single series bar chart

import javafx.stage.Stage;
public class DynamicallyColoredBarChart extends Application {
#Override
public void start(Stage stage) {
final CategoryAxis xAxis = new CategoryAxis();
xAxis.setLabel("Bars");
final NumberAxis yAxis = new NumberAxis();
yAxis.setLabel("Value");
final BarChart<String, Number> bc = new BarChart<>(xAxis, yAxis);
bc.setLegendVisible(false);
XYChart.Series series1 = new XYChart.Series();
for (int i = 0; i < 10; i++) {
// change color of bar if value of i is >5 than red if i>8 than blue
final XYChart.Data<String, Number> data = new XYChart.Data("Value " + i, i);
data.nodeProperty().addListener(new ChangeListener<Node>() {
#Override
public void changed(ObservableValue<? extends Node> ov, Node oldNode, Node newNode) {
if (newNode != null) {
if (data.getYValue().intValue() > 8) {
newNode.setStyle("-fx-bar-fill: navy;");
} else if (data.getYValue().intValue() > 5) {
newNode.setStyle("-fx-bar-fill: red;");
}
}
}
});
series1.getData().add(data);
}
bc.getData().add(series1);
stage.setScene(new Scene(bc));
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}

To put an image to the left you can just add image and chart to HBox:
HBox root = new HBox(5);
root.getChildren().addAll(image, bc);
stage.setScene(new Scene(root));
