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 == 11).Count(),
                                      grp.Where(c => c.Raised.Month == 12).Count() }

                          };


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

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
