[GitHub] [echarts] fff21 opened a new issue, #18616: [Feature]
fff21 opened a new issue, #18616:
URL: https://github.com/apache/echarts/issues/18616
### What problem does this feature solve?
轴线数值较大, 数据较小的时候挤在中间, 怎么才能让线的两头触底 (如图所示)
希望能得到解决方法(ﾉﾟ▽ﾟ)ﾉ

I'm sorry to close this issue for it lacks the necessary title. Please provide **a _descriptive_ and as _concise_ as possible title to describe your problems or requests** and then the maintainers or I will reopen this issue.
Every good bug report or feature request starts with a title. Your issue title is a critical element as it's the first thing maintainers see.
A good issue title makes it easier for maintainers to understand what the issue is, easily locate it, and know what steps they'll need to take to fix it.
Moreover, it's better to include keywords, as this makes it easier to find the issue self and similar issues in searches.
