Thank you! I just knew why it happened :) I just made the errorbars shorter, and they won't disappear any more. So I think maybe it's because my errorbars are too long and when I changed the max and min value of the YAxis, my errorbar's length was beyoned the max value which can be beared by the pane, so the errorbars disappeared. Thank you for help and happy new year!
