Unicode text such as chinese or japanese (for example: 人數) cannot be displayed on Y-axis legend vertically. If unicode text is specified on Y-axis, the legend area will show nothing. But unicode text can be used on title and x-axis legend.
By the way, link on bar chart is very important. I have tried the version posted by someone in this forum(sorry, forgot the name) and it works perfectly. Hope it will be implemented in future release soon.
Thank you very much for your hard work. Nice job.
