how to hide highchart x - axis data values

Question

I am drawing a bar chart using highchart.js

I do not want to show the x - axis data values.

Can any one tell me which option does it?
full config:

var chart = new Highcharts.Chart({
                chart: {
                    renderTo: container,
                    defaultSeriesType: 'bar'
                },
                title: {
                    text: null
                },
                subtitle: {
                    text: null
                },
                xAxis: {
                    categories: [''],
                    title: {
                        text: null
                    },
                    labels: {enabled:true,y : 20, rotation: -45, align: 'right' }

                },
                yAxis: {
                    min: 0,
                    gridLineWidth: 0,
                    title: {
                        text: '',
                        align: 'high'
                    }
                },
                tooltip: {
                    formatter: function () {
                        return '';
                    }
                },
                plotOptions: {
                    bar: {
                        dataLabels: {
                            enabled: true
                        },
                        pointWidth: 35,
                        color: '#D9CDC1'
                    }
                },
                legend: {
                    enabled: false
                },
                credits: {
                    enabled: false
                },
                series: [{
                    name: 'Year 1800',
                    data: [107]
                }]
            });

In HighCharts, bar graphs use inverted axes, so the bottom axis is really the Y axis. (See also "column" graphs where the graphic is rotated 90 degrees, in which case the bottom axis is the X axis.)

You need to add the following to the yAxis config

yAxis: {
  labels: {
    enabled: false
  }
}

See the following for full example: http://jsfiddle.net/k5yBj/433/
