x轴能放在最下面吗?echarts 折线配置项内容和展示

不想把X轴放在0点上,或者把X轴的点移上去? 还有Y轴的值在gallery为什么是这样的,很多个0000... 本地跑就不会?

配置项如下
      var now = +new Date();
var oneMinute = 60 * 1000;

function randomData() {
    now = new Date(+now + oneMinute);
    fatigue = Math.random() * 2 - 1;
    return {
        value: [
            [now.getHours(), now.getMinutes()].join(":"),
            Math.round(fatigue*100)/100
        ]
    }
}

var data = [];
var x = [];
var now = new Date()
for(var i = 0; i < 50; i++) {
    var item = randomData();
    data.push(item)
    x.push(item.value[0])
}

var option = {
        xAxis: {
        // type: 'catagory',
        //  boundaryGap: [0, '100%'],
        // splitLine: {
        //     show: false
        // },
        // position: "bottom",
        // offset: "10",
        data: x
    },
    yAxis: {
        type: 'value',
        // boundaryGap: [0, '100%'],
        splitLine: {
            show: false
        }
    },
    series: [{
        name: '模拟数据',
        type: 'line',
        showSymbol: false,
        hoverAnimation: false,
        data: data
    }]
};
