我是ASP.Net MVC的新手,我正在做一个项目,我必须使用数据库显示图表。假设数据库“Average”中有一个字段。如果我们针对某个特定用户ID找到4条记录,那么图形应该像4条形图,x轴上的每条形条代表1 2 3 4的数字,而在y轴上,应该是平均值。我尝试了很多东西,比如高级图表,但它不起作用,它给出了错误“无法找到DotNet(你是否缺少汇编参考)”。我搜索过它并得到了.net框架的问题。但老实说,我没有建立图表。我试过网络助手,通过这个我刚刚创建了一个图形图像,但不知道与数据库的热连接。
我试过但仍然没有使用highcharts 这是我的行动方法
public ActionResult Index()
{
Highcharts chart = new DotNet.Highcharts.Highcharts("chart")
.SetXAxis(new XAxis
{
Categories = new[] { "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" }
})
.SetSeries(new Series
{
Data = new Data(new object[] { 29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4 })
});
return View(chart);
}
这是我的view.cshtml
@model DotNet.Highcharts.Highcharts
@{
ViewBag.Title = "Index";
}
<header>
<script src="~/Scripts/jquery-1.5.1.min.js" type="text/javascript"></script>
<script src="~/Scripts/highcharts.js" type="text/javascript"></script>
</header>
@(Model)
所以请有人举例说明代码。我将不胜感激。

您可以按照这个简单的教程DotNet.Hightcharts。
这里有一些例子DotNet.Highcharts 4.0 with Examples。
这是一个有效的例子:
控制人员的行动
public virtual ActionResult GetWorkloadChart()
{
var chart = ConstructChart();
return View("WorkloadChart", chart);
}
构建图表
private static Highcharts ConstructChart()
{
var title = new Title() {Text = "Workload"};
var subtitle = new Subtitle() {Text = "workload per day"};
//You can get these values from database
var XData = new[] { "25", "26", "27", "28", "29", "30", "31", "01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12"};
var YData = new object[] { 195, 150, 0, 270, 0, 90, 245, 215, 350, 355, 190, 95, 0, 100, 225};
var xaxisTitle = new XAxisTitle { Text = "Wokload in minutes" };
var yaxisTitle = new YAxisTitle { Text = "Time in days" };
string serieName = "Workload per day";
Highcharts chart = new Highcharts("chart")
.SetTitle(title)
.SetSubtitle(subtitle)
.SetXAxis(new XAxis
{
Categories = XData,
Title = xaxisTitle
})
.SetYAxis(new YAxis
{
Title = yaxisTitle
})
.SetSeries(new Series
{
Data = new Data(YData),
Name = serieName
});
return chart;
}
查看
@model DotNet.Highcharts.Highcharts
@{
ViewBag.Title = "WorkloadChart";
}
<script src="~/Scripts/jquery-1.7.1.js" type="text/javascript"></script>
<script src="~/Scripts/Highcharts-2.2.1/js/highcharts.js" type="text/javascript"></script>
<h2>Workload Chart</h2>
@Model
请记住添加:
应该渲染到这样的东西:
