我尝试在.Net中使用HighCharts,但在填充HighChart在图表上使用的数据集时遇到了困难。最初,我使用以下代码在视图中执行此操作:

new BubbleSeries
{
     Data = (ViewData["bubble1"] as List<BubbleSeriesData>)
},

这是可行的,但它让我不得不在Razor视图中完成HighCharts的其余格式化工作。HighCharts没有很多在.Net中格式化不同图表对象的广泛示例,更多地依赖于利用JavaScript。
我想我会尝试一种不同的策略,在视图中的脚本标记中构建图表。我遇到的问题是如何将“ViewData”分配给数据对象。
如何替换此文件:

series: [{
            data: [
                { x: 95, y: 95, z: 13.8, name: 'BE', country: 'Belgium' },
                { x: 86.5, y: 102.9, z: 14.7, name: 'DE', country: 'Germany' },
                { x: 80.8, y: 91.5, z: 15.8, name: 'FI', country: 'Finland' },
                { x: 80.4, y: 102.5, z: 12, name: 'NL', country: 'Netherlands' },
                { x: 80.3, y: 86.1, z: 11.8, name: 'SE', country: 'Sweden' },
                { x: 78.4, y: 70.1, z: 16.6, name: 'ES', country: 'Spain' },
                { x: 74.2, y: 68.5, z: 14.5, name: 'FR', country: 'France' },
                { x: 73.5, y: 83.1, z: 10, name: 'NO', country: 'Norway' },
                { x: 71, y: 93.2, z: 24.7, name: 'UK', country: 'United Kingdom' },
                { x: 69.2, y: 57.6, z: 10.4, name: 'IT', country: 'Italy' },
                { x: 68.6, y: 20, z: 16, name: 'RU', country: 'Russia' },
                { x: 65.5, y: 126.4, z: 35.3, name: 'US', country: 'United States' },
                { x: 65.4, y: 50.8, z: 28.5, name: 'HU', country: 'Hungary' },
                { x: 63.4, y: 51.8, z: 15.4, name: 'PT', country: 'Portugal' },
                { x: 64, y: 82.9, z: 31.3, name: 'NZ', country: 'New Zealand' }
            ]
        }]

与此:

series: [{
            data: [
               (ViewData["bubble1"] as List<BubbleSeriesData>)
            ]
        }]

下面是一个工作示例:
型号:

public class BubbleSeriesData {
        public int x { get; set; }
        public int y { get; set; }
        public int z { get; set; }
        public string name { get; set; }
        public string country { get; set; }

    }

查看数据:

List<BubbleSeriesData> ll = new List<BubbleSeriesData> { new BubbleSeriesData { x = 1, y = 1, z = 1, name = "n1", country = "c1" }, new BubbleSeriesData { x = 2, y = 2, z = 2, name = "n2", country = "c2" } };
    ViewData["bubble1"] = JsonConvert.SerializeObject(ll);

系列:

series: [{
                data:@Html.Raw(JsonConvert.DeserializeObject(ViewData["bubble1"].ToString()))
            }],
