Awesome Chartecharts 柱状配置项内容和展示

大神们，帮帮忙，在xAxis -> axisLabel -> show 为false的情况下，怎么能让坐标轴刻度标签跟show为true时显示的一样？

      option = {
    title: {
        text: 'Awesome Chart'
    },
    grid: {
        borderWidth: 0
    },
    xAxis: {
        type: 'category',
        boundaryGap: true,
        data: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'],
        axisLine: {
            show: true
        },
        splitLine: {
            show: false
        },
        axisLabel: {
            show: false
        }
    },
    yAxis: {
        type: 'value',
        axisLine: {
            show: true
        },
        axisTick: {
            show: false
        },
        splitLine: {
            lineStyle: {
                color: '#efefef',
            }
        }
    },
    brush: {
        toolbox: ['lineX', 'keep', 'clear'],
        xAxisIndex: 'all',
        transformable: true,
        brushStyle: {
            borderWidth: 1,
            color: 'rgba(26,179,148,0.3)',
            borderColor: 'rgba(26,179,148,0.3)'
        },
        brushMode: 'single',
        brushType: 'lineX',
        removeOnClick: false,
        throttleType: 'debounce',
        throttleDelay: 300,
        inBrush: {
            colorAlpha: 1
        },
        outOfBrush: {
            colorAlpha: 1
        }
    },
    series: [{
        type: 'bar',
        data: [220, 182, 191, 234, 290, 330, 310]
    }]
};
