candlestick chart error

Hi i have two error for working on the candlestick chart. I have entered the time scale label and the data ({o:1, h:3, l: 1, c:2}, ) in the sample in the file to make a simple candlestick chart, but it appears to not work. no graph appears.(Please refer source 1)

Also, I have made a candlestick chart with line chart combined(please refer source2) but, does not work. instead, the bar+candlestick chart would appear not bad, but when pointing the mouse, the o,h,l,c value just shows NaH.

Sorry for bothering, but someone kindly tell me what I am wrong for issue? Thank you in advance
