echarts(3.0)的基本使用(标签式导入)

function loadRainFallCharts(msg) {
        var obj = {};
        obj.x = [];
        obj.y = [];
        obj.line = [];
        var accumulation = 0;
        $(msg).each(function () {
            obj.x.push(this.datatime);
            obj.y.push(this.avgvalue);
            accumulation += this.avgvalue;
            obj.line.push(accumulation);
        });
        var myChart = echarts.init(document.getElementById('inThePast6hours_rainfall'));
 
        var option = {
            title: {
                text: '实时雨量曲线(过去6小时)',
                subtext: '',
                x: 'center',
                align: 'right'
            },
            legend: {
                data: ['时段降水', '累积降水'],
                x: 'left'
            },
            tooltip: {

                axisPointer: {            // 坐标轴指示器，坐标轴触发有效

                }
