utils.ChartToSvg2 = function (chartIDList) {
    var height = 0;
    var data = [];
    for (var i = 0; i < chartIDList.length; i++) {
        var chartID = chartIDList[i];
        var chart = $(chartID).highcharts();
        var chartOption = $.extend(true, {}, chart.options);

        var prevOptions = {
            chart: {
                spacing: chartOption.chart.spacing,
                yAxis: chartOption.yAxis,
                height: chartOption.chart.height,
                width: chartOption.chart.width                
            },
            legend: {
                itemStyle: {
                    fontWeight: chartOption.legend.itemStyle
                }
            }
        };
        //根据图例文字数量判断图的高度
        height = utils.CovenrtHeight(chart.options, chart.options.chart.type);

        var opt = {
            chart: {
                spacing: [10, 10, 15, 10],
                yAxis: chartOption.yAxis,
                height: height,

            }
        }
        $.extend(true, chart.options, opt);
        var svg = chart.getSVG();
        //还原图表配置
        $.extend(true, chart.options, prevOptions);
        data.push(encodeURIComponent(svg));
