Array not in correct format in Javascript for use by HighChart

Question

Hi i'm passing a List object from my controller to Javascript where it is put back into an array and used as a data source for HighChart bar graph.

In my code below if i comment back in the raw data it WORKS. If I use my array variable called 'result' I get nothing

If I step into Javascript with debugger and output result to immediate window it looks like:

?result[0] {...} [0]: "2" [1]: {...}

?result[0][1] {...} [0]: 0 [1]: 0 [2]: 0 [3]: 0 [4]: 0 [5]: 0 [6]: 1 [7]: 0 [8]: 0 [9]: 0 [10]: 0 [11]: 0

HERE IS THE CODE :

function CreateChart3(surl) {

    // Code block for fetching Array as jsonResult (js)
    var url = $("#AbsolutePath").val() + "Complaint.mvc/GetChartData_MonthlyByType/" + surl;

    var chart;

    $.getJSON(url, null, function(data) {

        var result = [];
        jQuery.each(data, function(i, val) {
            result[i] = [val.Type, val.Count];
        });

        //            var seriesData = [];
        //            for (var i = 0; i < result.length; i++) {
        //                seriesData.push({ data: result[i][1] ,name: result[i][0]});
        //            }

        debugger;
        chart = new Highcharts.Chart({
            chart: {
                renderTo: 'chart3',
                defaultSeriesType: 'column',

            //                                        }, {

                }]

        });
    };

EXTRACT FROM CONTROLLER CODE IF IT HELPS......

         var qry = from i in _db.Complaints
                  where i.Site.SiteDescription.Contains(searchTextSite)
                       && (i.Raised >= startDate && i.Raised <= endDate)
                  group i by i.ComplaintNatureTypeId.ToString()
                      into grp
                      select new
                          {
                              Type = grp.Key,
                              Count = new int[] { 
                                  grp.Where(c => c.Raised.Month == 1).Count(),
                                      grp.Where(c => c.Raised.Month == 2).Count(),
                                      grp.Where(c => c.Raised.Month == 3).Count(),
                                      grp.Where(c => c.Raised.Month == 4).Count(),
                                      grp.Where(c => c.Raised.Month == 5).Count(),
                                      grp.Where(c => c.Raised.Month == 6).Count(),
                                      grp.Where(c => c.Raised.Month == 7).Count(),
                                      grp.Where(c => c.Raised.Month == 8).Count(),
                                      grp.Where(c => c.Raised.Month == 9).Count() ,
                                      grp.Where(c => c.Raised.Month == 10).Count() ,
                                      grp.Where(c => c.Raised.Month == 11).Count(),
                                      grp.Where(c => c.Raised.Month == 12).Count() }

                          };


        return Json(qry.ToArray(), JsonRequestBehavior.AllowGet);

Answer 1

As I remember data property of series is array of

1. y-values
2. pair of x-y values
3. point objects

As I understand every element of your array is array where element[0] is name and element[1] is array of y-values. So you have some number of series. You have to convert manually you result into array of { name: ..., data: ...} objects and pass it to HighCharts constructor. Use for loop:

var seriesData = [];
for (var i = 0; i < result.length; i++){
    seriesData.push({ name: result[i][0], data: result[i][1] });
}

And use series data like:

series: seriesData

Looking at the debugger output the JSON isn't what you're expecting.

Hard to say for definite but are you returning the correct object from the controller? It looks like you're returning qry when you should be using grp.
