Hi All,
Thank you for gave me advice and finally I got the root cause, it was because of data length. It was set '2' while the data is possible to get length of '5'. After I set it to '5', the graph and data works correctly in server now. While why the same worked fine when length = 2 at my local, I am not so sure.
Anyhow, again, thank you for help.
BR,
Yow
