[javascript] 추가 데이터를 highcharts 시리즈로 설정

AJAX를 사용하여 SQL Server에서 데이터를 가져온 다음 차트에서 데이터로 사용되는 js 배열을 준비합니다. AJAX가 성공하면 JavaScript 코드 :

...,
success: function (data) {
            var fseries = [];
            var series = [];
            for (var arr in data) {
                for (var i in data[arr]['data'] ){
                    var d = data[arr]['data'][i];
                    //if (i < 5) alert("d.method = " + d.method);
                    var serie = {x:Date.parse(d.Value), y:d.Item, method:d.method };
                    series.push(serie);
                }
                fseries.push({name: data[arr]['name'], data: series, location: data[arr]['location']});
                series = [];
            };
            DrawChart(fseries);
         },

이제 도구 설명에 추가 메타 데이터를 표시합니다.

...
tooltip: {
    xDateFormat: '%m/%d/%y',
    headerFormat: '<b>{series.name}</b><br>',
    pointFormat: 'Method: {point.method}<br>Date: {point.x:%m/%d/%y } <br>Reading: {point.y:,.2f}',
    shared: false,
},

DataRow를 사용하여 결과 집합을 반복 한 다음 클래스를 사용하여 Json 형식으로 다시 전달하기 전에 값을 할당합니다. 다음은 Ajax에서 호출하는 컨트롤러 작업의 C # 코드입니다.

public JsonResult ChartData(string dataSource, string locationType, string[] locations, string[] methods, string fromDate, string toDate, string[] lstParams)
{
    List<Dictionary<string, object>> dataResult = new List<Dictionary<string, object>>();
    Dictionary<string, object> aSeries = new Dictionary<string, object>();
    string currParam = string.Empty;

    lstParams = (lstParams == null) ? new string[1] : lstParams;
    foreach (DataRow dr in GetChartData(dataSource, locationType, locations, methods, fromDate, toDate, lstParams).Rows)
    {
        if (currParam != dr[1].ToString())
        {
            if (!String.IsNullOrEmpty(currParam))       //A new Standard Parameter is read and add to dataResult. Skips first record.
            {
                Dictionary<string, object> bSeries = new Dictionary<string, object>(aSeries); //Required else when clearing out aSeries, dataResult values are also cleared
                dataResult.Add(bSeries);
                aSeries.Clear();
            }
            currParam = dr[1].ToString();
            aSeries["name"] = cParam;
            aSeries["data"] = new List<ChartDataModel>();
            aSeries["location"] = dr[0].ToString();
        }

        ChartDataModel lst = new ChartDataModel();
        lst.Value = Convert.ToDateTime(dr[3]).ToShortDateString();
        lst.Item = Convert.ToDouble(dr[2]);
        lst.method = dr[4].ToString();
        ((List<ChartDataModel>)aSeries["data"]).Add(lst);
    }
    dataResult.Add(aSeries);
    var result = Json(dataResult.ToList(), JsonRequestBehavior.AllowGet);  //used to debug final dataResult before returning to AJAX call.
    return result;
}

C #으로 코딩하는 데 더 효율적이고 수용 가능한 방법이 있다는 것을 알고 있지만 프로젝트를 상속했습니다.
