VAADIN Charts: Disabling Label in Gauge chart

Hi all,
I’m trying to disable the display of the y-value in the middle of a gauge display, cause I need some other value there. (See the red circle in the attached display)

I tried

    chartConfig.getxAxis().getLabels().setEnabled(false);    

This works fine for ChartType.COLUMN, but not for ChartType.GAUGE.

Does anybody know how to kill that label ?

Thanks for any hint

Solved ( posted in the hope it helps somebody)
Found it in the plotOptions (not in the axis):

plotOptions.setDataLabels(new Labels(true));
plotOptions.getDataLabels().setEnabled(false);
