很遗憾我现在的兴趣不在这个项目上，可能最近不会为 chart.xkcd 添加新功能，不过很欢迎你在GitHub上提一个 issue，可能有人会去实现，或者我有空的时候会去实现 translate it to english

I'm sorry, but my interest is not in this project at the moment, so I may not be adding new features to chart.xkcd in the near future. However, you're welcome to open an issue on GitHub, and someone might implement it, or I might do it when I have time.
