从信息中使用igDataChart时出错
从信息中使用igDataChart时出错
提问于 2013-02-19 19:58:06
请帮助我解决这个问题：
无法从用法推断出方法“Infragistics.Web.Mvc.InfragisticsSuite.DataChart(System.Linq.IQueryable)”的类型参数。尝试显式指定类型参数。
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;

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()
)

您将视图中的模型定义为
@model MvcApplication2.Models.StockMarketDataPoint在传递列表的时候？尝试：
@model IQueryable<MvcApplication2.Models.StockMarketDataPoint>编辑:还要确保将IQueryable传递给视图，如下所示
return View(stockMarketData.AsQueryable());如果有必要的话。这将修复模型错误，但仍然不会让您的图表启动和运行-缺少轴和系列定义。例如，测试以下内容：
@(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()
)我建议您稍微熟悉一下图表:) Relevant sample和blog。
