An option to hide 0% text on pie charts

Please look at this example:

Here, the two 0% texts make no sense. It's getting even worse if there are many options. They just get stacked vertically and take a lot of space and look ugly.

An option to switch off showing zero-percent texts on pie charts would be very hepful.

Please note it's not the same as toggling pie slices when clicking on legend items, in which a case the opacity of those hidden legend items become 0.5 instead of 1 (default).

Issue 中没有指定源文件、测试或入口点。先定位饼图文本渲染和现有图表选项，然后验证新增选项可以仅抑制 0% 标签，同时保留其他标签，并且仍与图例项切换相互独立。
