asp.net mvc highchart linegraph json

我正试图在以下位置获取行示例:http://www.highcharts.com/demo/line-basic/grid使用jsonresult,但不知道如何实现。

控制器代码:

public JsonResult GetLineData()
    {
        Dictionary<string, double[]> retVal = new Dictionary<string, double[]>();
        double[] Array1 = {7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6};
        retVal.Add("Tokyo", Array1);
        double[] Array2 = { -0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5 };
        retVal.Add("New York", Array2);
        return Json(retVal.ToArray(), JsonRequestBehavior.AllowGet);
    }

我的jqquery看起来是这样的:

var chart;
    $(document).ready(function () {
        var options = {
            chart: {
                renderTo: 'container',
                defaultSeriesType: 'line',
                marginRight: 130,
                marginBottom: 25
            },
            title: {
                text: 'Monthly Average Temperature',
                x: -20 //center
            },
            subtitle: {
                text: 'Source: WorldClimate.com',
                x: -20
            },
            xAxis: {
                categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
        'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
            },
            yAxis: {
                title: {
                    text: 'Temperature (°C)'
                },
                plotLines: [{
                    value: 0,
                    width: 1,
                    color: '#808080'
                }]
            },
            tooltip: {
                formatter: function () {
                    return '<b>' + this.series.name + '</b><br/>' +
           this.x + ': ' + this.y + '°C';
                }
            },
            legend: {
                layout: 'vertical',
                align: 'right',
                verticalAlign: 'top',
                x: -10,
                y: 100,
                borderWidth: 0
            },
            series: []
        };
        //Calls the JSON            
        jQuery.getJSON("GetLineData", null, function (items) {
            var series = {
                name: '',
                data: []
            };                
            jQuery.each(items, function (itemNo, item) {
                //Get the items from the JSON and add then
                //to the data array of the series                               
                series.data.push({
                    name: item.Key,
                    data: item.Value
                })                    
            });
            options.series.push(series);
            //Create the chart
            chart = new Highcharts.Chart(options);
            chart.render();
        });

    });

图表显示时没有错误,但也没有两行。我想这个系列的构建方式不对吧?提前感谢您的帮助。

试试这个。我正在承担项目。值是一个数组,可以用作要提供给图表的数据。

//Calls the JSON            
        jQuery.getJSON("GetLineData", null, function (items) {
            var series = [];                
            jQuery.each(items, function (itemNo, item) {
                //Get the items from the JSON and add then
                //to the data array of the series                               
                series.push({
                    name: item.Key,
                    data: item.Value
                })                    
            });
            options.series = series;
            //Create the chart
            chart = new Highcharts.Chart(options);
            chart.render();
        });

我想你所需要做的就是代替

options.series.push(series);

进行

options.series = series;

或者将整个数组作为单个项目推入数组

使用DotNet.Higharts,您不需要考虑如何将数据从操作方法传递到javascript。您可以在服务器端构造和绑定所有内容。以下是带有此库的Basic Line的示例:

public ActionResult BasicLine()
    {
        Highcharts chart = new Highcharts("chart")
            .InitChart(new Chart
                       {
                           DefaultSeriesType = ChartTypes.Line,
                           MarginRight = 130,
                           MarginBottom = 25,
                           ClassName = "chart"
                       })
            .SetTitle(new Title
                      {
                          Text = "Monthly Average Temperature",
                          X = -20
                      })
            .SetSubtitle(new Subtitle
                         {
                             Text = "Source: WorldClimate.com",
                             X = -20
                         })
            .SetXAxis(new XAxis { Categories = ChartsData.Categories })
            .SetYAxis(new YAxis
                      {
                          Title = new XAxisTitle { Text = "Temperature (°C)" },
                          PlotLines = new[]
                                      {
                                          new XAxisPlotLines
                                          {
                                              Value = 0,
                                              Width = 1,
                                              Color = ColorTranslator.FromHtml("#808080")
                                          }
                                      }
                      })
            .SetTooltip(new Tooltip
                        {
                            Formatter = @"function() {
                                    return '<b>'+ this.series.name +'</b><br/>'+
                                this.x +': '+ this.y +'°C';
                            }"
                        })
            .SetLegend(new Legend
                       {
                           Layout = Layouts.Vertical,
                           Align = HorizontalAligns.Right,
                           VerticalAlign = VerticalAligns.Top,
                           X = -10,
                           Y = 100,
                           BorderWidth = 0

            .SetSeries(new[]
                       {
                           new Series { Name = "Tokyo", Data = new Data(new object[] { 7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6 }) },
                           new Series { Name = "New York", Data = new Data(new object[] { -0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5 }) },
                           new Series { Name = "Berlin", Data = new Data(new object[] { -0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0 }) },
                           new Series { Name = "London", Data = new Data(new object[] { 3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8 }) }
                       }
            );
        return View(chart);
    }
