努力将模型中的数据显示到剑道条形图中。 我想如示于下图中剑道条形图不显示数据
控制器返回有效数据,但图未能正确地显示数据条形图来显示结果。
模型
public class FeeCollectionViewModel
{
[Key]
public int FeeCollectionID { get; set; }
public int StudentID { get; set; }
public int FeeModeID { get; set; }
public int FeeTypeID { get; set; }
public string FeeTypeName { get; set; }
public double Amount { get; set; }
public DateTime CollectionDate { get; set; }
}
这里是查看
@using Kendo.Mvc.UI
@using Kendo.Mvc.Extensions
@{
ViewBag.Title = "Fee Statistics";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Fee Statistics</h2>
@(Html.Kendo().Chart<SMS.ViewModels.FeeCollectionViewModel>()
.Name("chart")
.Title("Today's Collection")
.Legend(legend => legend
.Position(ChartLegendPosition.Top)
)
.DataSource(ds => ds
.Read(read => read.Action("TodaysCollection_Read", "FeeCollections"))
.Group(group => group.Add(model => model.FeeTypeName))
)
.Series(series =>
{
series.Column(model => model.Amount).Name("Amount Collected");
})
.CategoryAxis(axis => axis
.Categories(model => model.FeeTypeName)
.Labels(labels => labels.Rotation(-90))
.MajorGridLines(lines => lines.Visible(false))
)
.ValueAxis(axis => axis.Numeric()
.Labels(labels => labels.Format("{0:N0}"))
.MajorUnit(10000)
.Line(line => line.Visible(false))
)
.Tooltip(tooltip => tooltip
.Visible(true)
.Format("{0:N0}")
)
)
如果添加'.AutoBind(true)',它会起作用吗?还要检查控制台中是否有任何相关的javascript错误,以及其他控件在视图或布局中是否具有ID“chart”。 – zgood
