After digging into the kendo javascript, i was able to successfully retrieve the json data that i had used before to bind the chart.
$("#OneMilePieChartMaleAge").data("kendoChart").options.series[0].data
The above line of code will return back the json that we have used before to bind the data, OneMilePieChartMaleAge is my div id.
I've checked the above code for both bar and pie chart of kendo. I hope this helps. Happy coding. :)
