Annotations

[MazZRud]

Hy I tried to use setHasAnnotations but have an error..
This is my code

    // Create Chart
    CategoryChart chart = new CategoryChartBuilder().width(800).height(600).title("Score Histogram").xAxisTitle("Score").yAxisTitle("Number").build();
 
    // Customize Chart
    chart.getStyler().setLegendPosition(LegendPosition.OutsideE);
    chart.getStyler().setLegendVisible(false);
    
    //Setta il titolo "vuoto" e anche delle serie
    chart.setTitle("");
    chart.setXAxisTitle("");
    chart.setYAxisTitle("");
    
    //Set background color area esterna al grafico
    Color b = new Color(235,235,235);
    chart.getStyler().setChartBackgroundColor(b);
    //Set background color area interna al grafico
    chart.getStyler().setPlotBackgroundColor(b);
    
    //Setta la doppia riga dei dati ad invisible
    chart.getStyler().setAxisTicksLineVisible(false);
    //Setta visible o meno i dati di riferimenento delle serie
    //chart.getStyler().setAxisTicksVisible(false);
    
    //Setta visible il bordo esterno del grafico
    chart.getStyler().setPlotBorderVisible(false);
    
    //Setta invisible le righette interne al grafico
    chart.getStyler().setPlotGridLinesVisible(false);
    
    Color[] c = new Color[] {new Color(82,148,165)};
    chart.getStyler().setSeriesColors(c);
    
    //Setta il colore del testo delle scritte in x e y
    Color t = new Color(64,65,66);
    chart.getStyler().setAxisTickLabelsColor(t);
    //Setta il font del testo delle scritte in x e y
    chart.getStyler().setAxisTickLabelsFont(new Font("Segoe Ui", 0, 11));
    
    
    chart.getStyler().setHasAnnotations(true);
    // Series
    chart.addSeries("test 1", Arrays.asList(new String[] { "Rep1", "Rep2", "Rep3", "Rep4", "Rep5" }), Arrays.asList(new Integer[] { 4, 5, 9, 6, 5 }));

This line chart.getStyler().setHasAnnotations(true); gives me the error "The method setHasAnnotations(boolean) is undefined for the type CategoryStyler" and suggests me to CAST to chart.getStyler()
Any idea ?
