AreaChart use only XYChart<String, Number>

[dpozimski]

Hello!

I would like to make a ticket with this issue:

When i try to build a new Tile with series of type XYChart<Number, Number> to use it for dynamic visualization i am getting:

Exception in thread "JavaFX Application Thread" java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String

To reproduce problem use snippet and put it into Main code:

    private void init(Stage primaryStage) {
        //-- Chart Series
        Series series = new XYChart.Series<Number, Number>();
        series.setName("Temperature");

        Tile sc = TileBuilder.create()
                .prefSize(800, 240)
                .skinType(Tile.SkinType.AREA_CHART)
                .series(series)
                .animated(true)
                .build();

        for(int i=0;i<100;i++)
              series.getData().add(new XYChart.Data(i, i+1));;

        primaryStage.setScene(new Scene(sc));
        primaryStage.setWidth(800);
        primaryStage.setHeight(240);
        primaryStage.show();
    }

Maybe I'm late but I was having a look at this and I found that it already works: you only have to provide the Axis. So it will work if you change your code like this:

        Series series = new XYChart.Series<Number, Number>();
        series.setName("Temperature");

        Axis<Number> vXAxis = new NumberAxis();
        
        Tile sc = TileBuilder.create()
                .prefSize(800, 240)
                .skinType(Tile.SkinType.AREA_CHART)
                .xAxis(vXAxis)
                .series(series)
                .animated(true)
                .build();

Thank you for your feedback very well, but I resolved this issue in the past by replacing the AreaChart with standard Chart from jdk.
I am really happy that i have got a response after a long time :)

You're welcome. Maybe this issue should be closed now?

Yes of course, but I can propose to add programmer friendly exception for that case (missmath between series generic types and xAxis or something like that)
