echarts3 动态图的问题

官方那个折现图的动态跑不起,不知道为什么。


网上找了一个网友的能跑,但是他改成累积了,地址:

var app = {};
       option = {
    title: {
        text: '动态数据',
        subtext: '纯属虚构'
    },
    tooltip: {

            boundaryGap: true,

                var res = [];

                return res;

                var len = 0;
                return res;

        }
    ],

            name: '预购量',
            max: 1200,
            min: 0,
            boundaryGap: [0.2, 0.2]
        }
    ],
    series: [
        {
            name:'预购队列',
            type:'bar',
            xAxisIndex: 1,
            yAxisIndex: 1,
            data:(function (){
                var res = [];
                var len = 10;

                return res;
            })()
        },
        {

            data:(function (){
                var res = [];
                var len = 0;
                return res;
            })()
        }
    ]
};
clearInterval(app.timeTicket);
app.count = 1;
app.timeTicket = setInterval(function (){
    axisData = (new Date()).toLocaleTimeString().replace(/^\D*/,'');

    var data0 = option.series[0].data;
    var data1 = option.series[1].data;
    data0.push();
    data0.push(Math.round(Math.random() * 1000));
    data1.push();
    data1.push((Math.random() * 10).toFixed(1) - 0);

    option.xAxis[0].data.push();
    option.xAxis[0].data.push(axisData);
    option.xAxis[1].data.push();
    option.xAxis[1].data.push(app.count++);

    myChart.setOption(option);
}, 1000);



我不想要累积的,然后在官方的柱形图里,找到一个和上面这个网友类似的,复制下来,跑不起,报错是app未定义,加上一句,跑起来了

之前改的思路是对的,但是对echarts不熟悉,所以改了半天都没改成功。echarts2的动态图,拿到3下面来,跑不起。
