Unable to format JSON from WCF for HighCharts? - json

Question

My WCF returns this JSON and i want to bind to HighCharts Pie
Original from WCF -[{"AllRecordsUrl":"http:\/\/EMS\/sites\/IST\/report.aspx","EMSCenterName":"IST","EMSCenterUrl":"http:\/\/EMS\/sites\/IST","Count":2},{"AllRecordsUrl":"http:\/\/EMS\/sites\/LSS\/report.aspx","EMSCenterName":"LSS","EMSCenterUrl":"http:\/\/EMS\/sites\/LSS","Count":17}]
If i hardCode it in cart series as data: [....] it works but the dynamic proccesed data does not..
After processing - [{name: 'IST' , url: 'http://EMS/sites/IST/report.aspx' , y: 2 },{name: 'LSS' , url: 'http://EMS/sites/LSS/report.aspx' , y: 16 }]
Even after processing it to what i showed above highcharts Pie won't work with my data..
I am not sure what is wrong here, would appreciate some guidance
Here's what is done so far ...
function getDataForHub(json) {
var realArray = $.makeArray(json);
//debugger;
//console.log(JSON.stringify(realArray));
var obj = $.parseJSON(JSON.stringify(realArray));
var chartData = [];
$.each(realArray, function (index, item) {
var final;
var element;
var sB = '';
var name = '';
var url = '';
var y = '';
var color = '';
for (element in item) {
if (element == 'EMSCenterName') {
name = 'name' + ": " + "'" + item[element] + "'";
}
if (element == 'AllRecordsUrl') {
url = 'url' + ": " + "'" + item[element] + "'";
}
if (element == 'Count') {
y = 'y' + ": " + item[element];
}
}
sB = name + ' , ' + url + ' , ' + y ;
//console.log(sB);
var elements = [];
//adding each to an array before being pushed to th final array,
elements.push(sB);
chartData.push(elements);
});
return chartData;
}
And here is my Pie
$(function () {
LoadSodByKey("sp.ui.dialog.js", null);
var stdWidth = 530;
var stdHeight = 200;
Highcharts.setOptions({
colors: ['#50B432', '#ED561B', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4']
});
$('#containerpie').highcharts({
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: true,
height: stdHeight + 120,
width: stdWidth + stdHeight
},
title: {
text: 'Records per Program'
},
tooltip: {
pointFormat: '{point.name}: <b>{point.percentage:.1f}%</b>'
/*formatter: function () {
return '<b>' + this.point.name;
}*/
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '<b>{point.name}</b>: {point.percentage:.1f} %'
},
showInLegend: false
}
},
series: [{
type: 'pie',
size: stdHeight,
data:[{name: 'IST' , url: 'http://EMS/sites/IST/report.aspx' , y: 2 },{name: 'LSS' , url: 'http://EMS/sites/LSS/report.aspx' , y: 16 }],
point: {
events: {
click: function(e) {
//alert(e.point.url);
var options = {
url: e.point.url,
title: e.point.name,
allowMaximize: true,
showClose: true,
width: 1100,
height: 500,
dialogReturnValueCallback: function (result, returnValue) {
//location.reload(true);
}
}
SP.UI.ModalDialog.showModalDialog(options);
e.preventDefault();
}
}
}
}]
});
var data = GetData();});
function GetData(){
var chart = $('#containerpie').highcharts();
series = chart.series[0];
//Ajax call to WCF service
$.ajax({
type: 'GET',
contentType: 'application/json; charset=utf-8',
crossDomain: false,
url: 'http://EMS/_vti_bin/EMSDashboard.svc/GetEMSCenterDataForHub',
data: null,
dataType: 'json',
success: function (response) {
var dynamicData = getDataForHub(response);
//this doesnot work
//series.data = dynamicData;
//even this does not work
//series.data.push(dynamicData)
//Wrong, wrong, wrong
//series.data.push(eval('[' +dynamicData +']'));
//gives me count of two but the chart does not load wiht dynamic data
console.log(series.data.length);
},
error: function (message) {
alert(message.statusText);
}
});
}
Thanx

FIXED:
Here's how
mistake = I had set up a static chart and was trying to use the same with $AJAX call where the chart was already created without the "data" being created, instead now the "data" array is created first and then the chart is created using chart = new Highcharts.Chart({....})
Also removed all client side preprocessing of the JSON received from WCF i.e my server object has additional Properties for Highchart rendering such to get ..
[{"name":"IST","url":"http:\/\/<XXXX>\/sites\/IST\/ASASA.aspx","y":2},
{"name":"LASS","url":"http:\/\/<XXXX>\/sites\/LASS\/ASASA.aspx","y":17}]
