JavaFX Chart Axis only shows last label

I have the following problem when using any JavaFX Chart: I dynamically add data to the chart and only the last X-Axis label shows up.

I already noticed that the chart is displayed fine when animations are disabled.

    XYChart.Series<String,Double> series1= new Series<String, Double>();
    series1.setName(scenario1.getName());

    XYChart.Series<String,Double> series2= new Series<String, Double>();
    series2.setName(scenario2.getName());


    for(int period = 0; period < config1.getPeriods(); period++){
        series1.getData().add(new Data<String, Double>("Period "+(period+1), rmList1.get(0).getCashflowsPerPeriod(config1)[period]));
        System.out.println("Series1: "+rmList1.get(0).getCashflowsPerPeriod(config1)[period]);
    }


    for(int period = 0; period < config2.getPeriods(); period++){
        series2.getData().add(new Data<String, Double>("Period "+(period+1), rmList2.get(0).getCashflowsPerPeriod(config2)[period]));
        System.out.println("Series2: "+rmList2.get(0).getCashflowsPerPeriod(config2)[period]);
    }

    sacCashflows.getData().addAll(series1,series2);

Chart with missing axis labels Can you help me out here? Thank you!

Here is a quick-n-dirty fix for this bug:

chartVariable.getData().add(new XYChart.Series(FXCollections.observableArrayList(new XYChart.Data("",0))));
chartVariable.getData().clear();

While initializing the chart, add fake data and then remove it. This works because the bug gets resolved after the first update/change to the chart. Setting animation to false also works, but I like the animations.

change your code like this

    xAxis1.setAnimated(false);
    yAxis1.setAnimated(true);
    barChart.setAnimated(true);

Disabling the animation worked for me.

sacCashflows.setAnimated(false);

I know you said in the comments that you had already tried that and it hadn't worked, but maybe for someone else having the same problem it will.

Let's try with sample code (JavaFX-8-b40):

@Override
public void start( Stage stage )
{

    CategoryAxis xAxis = new CategoryAxis();
    NumberAxis yAxis = new NumberAxis();

    AreaChart<String, Number> sacCashflows = new AreaChart<>( xAxis, yAxis );

    Button b = new Button( "Add" );
    b.setOnAction( new EventHandler<ActionEvent>()
    {
        @Override
        public void handle( ActionEvent event )
        {
            XYChart.Series<String, Number> series1 = new XYChart.Series<>();
            series1.setName( "series1" );

            XYChart.Series<String, Number> series2 = new XYChart.Series<>();
            series2.setName( "series2" );

            for ( int period = 0; period < 10; period++ )
            {
                series1.getData().add( new XYChart.Data<>( "Period " + (period + 1), 5.0 * period ) );
            }

            for ( int period = 0; period < 5; period++ )
            {
                series2.getData().add( new XYChart.Data<>( "Period " + (period + 1), 10.0 * period ) );
            }

            sacCashflows.getData().addAll( series1, series2 );

        }
    } );

    final Scene scene = new Scene( new VBox( sacCashflows, b ), 400, 300 );
    stage.setScene( scene );
    stage.show();
}
