echarts series里面没有值怎么办？

Question

echarts series里面无法获取数据怎么办？后端用的flask传送一个二维元组，四条曲线想分别取每一个小元组的值x轴用的是实时时间。

<div id="suspension" style="width:300px; height:300px;">
    {% for new_result in result%}
    <script src="js/echarts.js" type="text/javascript" charset="utf-8"></script>
    <script type="text/javascript">
        var myChart = echarts.init(document.getElementById('suspension'));
        var option;
        function randomData() {
        var now = new Date();
        value = value + Math.random() * 21 - 10;
        return {
            value: [
                [now.getHours(), now.getMinutes(), now.getSeconds()].join(':'),
                Math.round(value)
            ]
        }
    }

    var data = [];
    var date = [];
    var value = Math.random() * 1000;
    for (var i = 0; i < 1000; i++) {
        data.push(randomData());
        date.push('')
    }

    myChart.setOption(option);
    </script>

</div>

把循环体放进script标签内，无反应。
把循环体放在外面，会不断创建div模块，series也没有数据。我该怎么样让result的数据显示在series里啊？
