How create a XYChart.Series from and ObservableList

Question

I have a simple ObservableList made up of ChartPoints - a class that contains a String and a Double with all the setters and getters.
its named chart1Data. I am trying to create a BarChart to use the chart1Data.
How do I get the XYChart.Series to load the list?.
I get a no suitable method found error.
Here is my code
The ChartPoint class
import javafx.beans.property.SimpleDoubleProperty;
import javafx.beans.property.SimpleStringProperty;
public class ChartPoint {
    public final SimpleStringProperty description;
    public final SimpleDoubleProperty amount;
    public ChartPoint(String desc, Double amt) {
    this.description = new SimpleStringProperty(desc);
    this.amount = new SimpleDoubleProperty(amt);
    public String getDescription() {
        return description.get();
    public void setDescription(String desc) {
        description.set(desc);
    public SimpleStringProperty descriptionProperty() {
        return description;
    public Double getAmount() {
        return amount.get();
    public void setAmount(Double amt) {
        amount.set(amt);
    public SimpleDoubleProperty amountProperty() {
        return amount;
The Class to draw the Chart
public class FinX2ChartClass {
       private Stage chart1Stage = null;
        @FXML private static BarChart<String, Number> bc1;
        XYChart.Series<String, Number> series1 = new XYChart.Series<>();
private static final ObservableList<ChartPoint> chart1Data = FXCollections.observableArrayList(
     new ChartPoint ("April",10.00),
     new ChartPoint ("May", 20.00),
     new ChartPoint ("June", 30.00));
    public void makeStage() throws IOException {
        chart1Stage = new Stage();
        Parent root = FXMLLoader.load(getClass().getResource("FinX2Chart1.fxml"));
// This approach does not work error no suitable method found
       series1.getData().add(chart1Data );
        bc1.getData().addAll(series1);
        chart1Stage.setScene(new Scene(root));
        root.getStylesheets().add("supportfiles/chartstylesheet.css");
        chart1Stage.show();
public ObservableList<ChartPoint> getPoints() {
        return chart1Data;
public void closeStage(){
         chart1Stage.close();
The complier error message
\ error: no suitable method found for add(ObservableList<ChartPoint>)
series1.getData().add(chart1Data );
method List.add(int,Data<String,Number>) is not applicable
(actual and formal argument lists differ in length)
method List.add(Data<String,Number>) is not applicable
(actual argument ObservableList<ChartPoint> cannot be converted to Data<String,Number> by method invocation conversion)
Note: /Users/David/NetBeansProjects/FinX2/src/finx2/FinX2ChartClass.java uses unchecked or unsafe operations.

Can anyone point me in the right direction

Thanks for your suggestion but with your proposed change I now get another error. I have shown where in the code the errors are
See bottom of post for error detail
Any thoughts ?
the revised chart class
public class FinX2ChartClass {
       private Stage chart1Stage = null;
        @FXML private static BarChart<String, Number> bc1;
        XYChart.Series<String, Number> series1 = new XYChart.Series();
//*** The next line gives an incompatible types error
private static final ObservableList<XYChart<String,Number>> chart1Data = FXCollections.observableArrayList(
     new XYChart.Data("April", 10.00),
     new XYChart.Data("May", 20.00),
     new XYChart.Data("June", 30.00));
    public void makeStage() throws IOException {
        chart1Stage = new Stage();
        Parent root = FXMLLoader.load(getClass().getResource("FinX2Chart1.fxml"));
//*** The next line gives a no suitable method found error
       series1.getData().add(chart1Data );
        bc1.getData().addAll(series1);
        chart1Stage.setScene(new Scene(root));
        root.getStylesheets().add("supportfiles/chartstylesheet.css");
        chart1Stage.show();
public void closeStage(){
         chart1Stage.close();
