Please help me to get out of this error as soon as possible.

Thanks in advance..

Hi Mandeep,

I can see the chart series type is line, while the attached image shows bars. I am not really sure about the reason for such behavior, do you alter the chart series and datasource elsewhere in the code?. I created a small example, which follow basically the same structure -- a single line series within the chart and the chart is populated by a dataset. It works correctly for me, you can find it attached.
