Hi
I have a kendo line chart that needs to show dynamic chart

when I use some static source like

var employeeTracks = [
{
"week": "W1",
"year": "2015",
"value": 6
},
{
"week": "W2",
"year": "2015",
"value": 7
}
];


the line chart works but when I try to create json object and use that, then it does not work. Can any one help on this please ... its urgent thanks

What I have tried:

public string GetJsonResult([DataSourceRequest]Kendo.Mvc.UI.DataSourceRequest request)
{

string a = "[{ \"week\":\"W2\", \"year\":2015,\"value\":7}]";
return a;

}
