[Solved]-adding series to highcharts from JSON-Highcharts

Check the response(JSON DATA) coming through ajax having datatype as object or not. Because highcharts will work it the response is of datatype as object.

If it is returning as string then, convert it into object using eval('(' + response + ')')

In an example from a project I'm working on right now, I evaluate the series data from an array like this. Maybe that is cheating, but I at least got it to work :)

var xAxisCat = new Array();
var hSeries = new Array();
for (var datevote in contestantObject.contestants[cObj].votes)
{
    xAxisCat.push(datevote);
    hSeries.push(contestantObject.contestants[cObj].votes[datevote]);
}
var setSeries = "["+hSeries+"]";

And then, at the series creation I evaluate the created array instead:

series: [{
         name: contestantObject.contestants[cObj].name,
         data: eval(setSeries)
         }]

I figured this out. Here's how I did it in case anyone else has the same question:

In my script that generates the JSON data, I did the following:

    header('Content-type: text/json');

    //Placeholder - random data for now
    $x1 = "2011-8-1";
    $y1 = rand(0, 100);

    $x2 = "2011-8-2";
    $y2 = rand(0, 100);

    //Generate this array from database data
    $arr = array($x1 => $y1, $x2 => $y2);

    echo json_encode($arr);

Then, in the ajax script that adds the series to the chart, I did the following:

    function requestData() {
 $.ajax({
    url: 'chartData.php',
    success: function(json) {

        var series = {
            id: 'series',
            name: 'JSON Data',
            data: []
            }

        $.each(json, function(date,value) {
            xval = date.split("-");
            x = Date.UTC(xval[0], xval[1] - 1, xval[2]);
            series.data.push([
                x,
                value
            ]);
        });

        chart.addSeries(series);

    },
    cache: false
});
}
