Echarts高级进阶教程(3)：appendData大数据量分片加载数据增量渲染和常规思路异步加载数据的对比，对折线图是无效的

    //模拟数据;
    var dataList = [], dataName = [];
    var newData = 1000000;
    for (var i = 1; i < newData; i++) {
        dataName.push(i);
        //dataList.push({name: i, value: i + parseInt(Math.random() * 100)});
        dataList.push([i, i + parseInt(Math.random() * 100)]);
    }

    var option = {
        tooltip: {
            trigger: 'axis',
            axisPointer: {
                type: 'cross',
                label: {
                    backgroundColor: '#6a7985'
                }
            }
        },
        dataZoom: [{
            //show: true,
            //type: "inside",
            start: 50,
            end: 100,
            bottom: 10,
        }],
        xAxis: {
            data: dataName
        },
        yAxis: {},

    myChart.setOption(option, true);
    window.addEventListener("resize", function () {
        myChart.resize();
    });
    myChart.appendData({
        seriesIndex: 0,
        data: dataList,
    });
    myChart.resize();

    //渲染图表;
