錯誤而使用igDataChart從Infragistics的

請幫我解決這個問題：錯誤而使用igDataChart從Infragistics的

的方法「Infragistics.Web.Mvc.InfragisticsSuite類型參數。 DataChart（System.Linq.IQueryable）'不能從使用中推斷出來。嘗試明確指定類型參數。

模型

  namespace MvcApplication2.Models 
      { 
       public class StockMarketDataPoint 
       { 
        public double Open { get; set; } 
        public double High { get; set; } 
        public double Low { get; set; } 
        public double Close { get; set; } 
        public double Volume { get; set; } 
        public DateTime Date { get; set; } 
        public string DateString { get { return Date.ToShortDateString(); } } 
       } 
      }

控制器

    public class Default1Controller : Controller 
       { 
         public ActionResult Index() 
         { 
           List<StockMarketDataPoint> stockMarketData = new List<StockMarketDataPoint> 
         { 
           new StockMarketDataPoint { Date = DateTime.Parse("2.1.2010"), Open = 1000, High = 1028.75, Low = 985.25, Close = 1020, Volume = 1995 }, 

           new StockMarketDataPoint { Date = DateTime.Parse("3.1.2010"), Open = 1020, High = 1032.5, Low = 999.5, Close = 1021, Volume = 1964.5 }, 

          new StockMarketDataPoint { Date = DateTime.Parse("4.1.2010"), Open = 1021, High = 1033.5, Low = 996, Close = 1033, Volume = 1974.75 }, 

          new StockMarketDataPoint { Date = DateTime.Parse("5.1.2010"), Open = 1033, High = 1062, Low = 1018.75, Close = 1042, Volume = 1978.5 }, 

          new StockMarketDataPoint { Date = DateTime.Parse("6.1.2010"), Open = 1042, High = 1058.5, Low = 1019.75, Close = 1029, Volume = 1979 }, 

          new StockMarketDataPoint { Date = DateTime.Parse("7.1.2010"), Open = 1029, High = 1050.75, Low = 1006, Close = 1042, Volume = 1990 } 
         }; 

         return View(stockMarketData); 
        } 
       }

index.cshtml

  @using Infragistics.Web.Mvc 

      @model MvcApplication2.Models.StockMarketDataPoint 

      @{ 
       Layout = null; 
      } 

      <!DOCTYPE html> 

      <html> 
      <head> 
       <meta name="viewport" content="width=device-width" />

      </head> 
      <body> 

       Here is a chart 

       @(Html.Infragistics().Loader() 
        .ScriptPath(Url.Content("~/Infragistics/js/")) 
        .CssPath(Url.Content("~/Infragistics/css/")) 
        .Render() 
        ) 

       @(Html.Infragistics().DataChart(Model) 
       .ID("chart") 
       .Width("500px") 
       .Height("500px") 
       .CrosshairVisibility(Visibility.Visible) 
       .DataBind() 
       .Render() 
      ) 

      </body> 
      </html>

您正在定義視圖中的模型中作爲

@model MvcApplication2.Models.StockMarketDataPoint

雖然通過一個列表？嘗試：

@model IQueryable<MvcApplication2.Models.StockMarketDataPoint>

編輯：另外，還要確保你傳遞的IQueryable的視圖中

return View(stockMarketData.AsQueryable());

，如果你要。這將修復模型錯誤，但仍然不會讓您查看並運行圖表 - 缺少軸和系列定義。經測試此例如：

@(Html.Infragistics().DataChart(Model) 
    .ID("chart") 
    .Width("500px") 
    .Height("500px") 
    .CrosshairVisibility(Visibility.Visible) 
    .Axes((axes) => 
    { 
     axes.CategoryX("xAxis") 
      .Label((item) => item.Date) 
      .LabelVisibility(Visibility.Collapsed); 
     axes.NumericY("yAxis"); 
    }) 
    .Series(series => 
    { 
     series.Financial("stockSeries") 
     .CloseMemberPath("Close").OpenMemberPath("Open").HighMemberPath("High").LowMemberPath("Low") 
     .XAxis("xAxis").YAxis("yAxis"); 
    }) 
    .DataBind() 
    .Render() 
)

我建議你熟悉圖表一點:) Relevant sample和blog。
