Vaadin Charts 3.2 - Error setting yAxis categories on gauge

Hi, 

I tried creating a Gauge chart that looks like a "wind rose" to indicate wind direction on realtime. 
I'm facing the issue when I want to change the yAxis labels from degrees to categories (N, NE, E, SW, S, SW, NW)
When setting it this way it shows only the N at the position 0 and the rest the numbers. 

What gets displayed is N, 45, 90, 135,... 315

All source:

protected Component getChart() {
        final Chart chart = new Chart();
        chart.setSizeFull();

        final Configuration configuration = chart.getConfiguration();
        configuration.getChart().setType(ChartType.GAUGE);
        configuration.getChart().setAlignTicks(false);
        configuration.getChart().setPlotBorderWidth(0);
        configuration.getChart().setPlotShadow(false);
        configuration.getChart().setAnimation(Boolean.FALSE);
        configuration.setTitle("Wind Direction");
        Style style = new Style();
        style.setFontSize("20px");
        style.setColor(new SolidColor(25, 125, 225));
        configuration.getTitle().setStyle(style);

        configuration.getPane().setStartAngle(0);
        configuration.getPane().setEndAngle(360);
        configuration.getPane().setSize("102%");

        Background bg = new Background();
        bg.setBackgroundColor(new SolidColor(250, 250, 250));
        configuration.getPane().setBackground(bg);

        YAxis yAxis = configuration.getyAxis();
        yAxis.setMin(0);
        yAxis.setMax(359);
        yAxis.setLineColor(new SolidColor("#339"));
        yAxis.setTickColor(new SolidColor("#339"));
        yAxis.setMinorTickColor(new SolidColor("#339"));
        //yAxis.setOffset(-25);
        yAxis.setGridLineWidth(2);
        yAxis.setTickInterval(22.5);
        
        yAxis.setLineWidth(2);
        Labels labels = new Labels();
        labels.setDistance(-20);
        labels.setRotationPerpendicular();
        labels.setRotation("auto");
        labels.setStep(2);
    
        yAxis.setLabels(labels);
        yAxis.setType(AxisType.CATEGORY);
        yAxis.setCategories("N", "NNE", "NE", "ENE", "E", "ESE", "SES", "S", "SSW", "SW", "SWW", "W", "WNW", "NW", "NNW");
        //yAxis.setTickLength(5);
        //yAxis.setMinorTickLength(5);
        yAxis.setEndOnTick(false);

        RealTimeEntry rtData = RealTimeProvider.get();
        final ListSeries series = new ListSeries("Direction", rtData.getV6());

        PlotOptionsGauge plotOptionsGauge = new PlotOptionsGauge();
        plotOptionsGauge.setDataLabels(new DataLabels());

        GradientColor gradient = GradientColor.createLinear(0, 0, 0, 1);
        gradient.addColorStop(0, new SolidColor("#DDD"));
        gradient.addColorStop(1, new SolidColor("#FFF"));
        plotOptionsGauge.getDataLabels().setBackgroundColor(gradient);
        series.setPlotOptions(plotOptionsGauge);

        configuration.setSeries(series);

        runWhileAttached(chart, () -> {
            RealTimeEntry rtData1 = RealTimeProvider.get();
            series.updatePoint(0, rtData1.getV6());
        }, 2000, 2000);

        chart.drawChart(configuration);

        return chart;
    }

Maybe this is a bug?
