Question

型号：

 public class TemperatureData
    {
        public string name { get; set; }
        public double[] data { get; set; }
    }

控制器：

[HttpPost]
    public ActionResult GetData()
    {
        var json = "";
        try
        {
            List<TemperatureData> PlotData = new List<TemperatureData>();

            PlotData.Add(new TemperatureData
            {
                name = "Tokyo",
                data = new double[] {7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2,
                  26.5, 23.3, 18.3, 13.9, 9.6}
            });
            PlotData.Add(new TemperatureData
            {
                name = "New York",
                data = new double[] {-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8,
                  24.1, 20.1, 14.1, 8.6, 2.5}
            });

            var jsonsrlzr = new JavaScriptSerializer();
             json = jsonsrlzr.Serialize(PlotData);

        }
        catch (Exception ex)
        {
        }
        return Json(json);
    }

我正在序列化并返回作为对ajax调用的响应。

查看：

    $(document).ready(function () {

    $.ajax({
        type: "POST",

            legend: {

                borderWidth: 0
            },
            series: seriesdata


        };
        $('#container').highcharts(options);
    }

});

图表没有绘制？难道我做错了什么？？我是MVC的新手。

如果我直接给出系列值，如下所示

series: [
               {
                   name: seriesdata.na,
                   data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2,
                      26.5, 23.3, 18.3, 13.9, 9.6]
               },
               {
                   name: 'New York',
                   data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8,
                      24.1, 20.1, 14.1, 8.6, 2.5]
               },
               {
                   name: 'London',
                   data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0,
                      16.6, 14.2, 10.3, 6.6, 4.8]
               }
            ]

图表显示并绘制得很好。

需要帮助感谢
