Please guide me how can i get pie chart with Remote json data...
I am fairly new to KendoUI as well, but I believe that your problem bit of code is here:
I believe this "data" section would be necessary if you need to manipulate the incoming JSON data to match the object names Kendo is looking for, in your case "Amount" and "RangeValue". It may be that you do need to manipulate it. Put a function in there and a breakpoint to verify your data is good:
To me, that error message is saying it is not getting an array as expected, or maybe the object array its getting back is not formatted correctly so it can not be sliced as it wants.
