Awesome Chartecharts 折线配置项内容和展示

如果在X轴固定显示2,4,8,16,32,64,65 而不是自动生成的10,20,30,40...

配置项如下
      option = {
    title: {
        text: 'Awesome Chart'
    },
     tooltip: {
         
        trigger: 'axis'
    },
    legend:{
      data:['上限']  
    },
    xAxis: {
        type:'value'
    },
    yAxis: {},
    series: [{
        name:"上限",
        type: 'line',
        lineStyle:{
            normal:{
                color:'#99FF99',
                width:6
            }
        },
        data:[[2,220], [4,182], [8,191], [16,234], [32,290], [64,330], [65,310]]
    },
    {
        name:'2017-01-01',
        type: 'line',
        data:[[2,231], [4,193], [8,291], [16,244], [32,310], [64,340], [65,330]]
    } ]
};
