## General Questions
- [x] I have read the document and examples and tried to solve it by myself.
- [x] I have searched for similar issues and that didn't help.
- [x] I have tried with the latest version of ECharts and still have this problem.
In this issue, I have provided information with:
- [x] issue type
- [x] one sentence description in issue details
- [ ] demo if this is bug report
## Issue Type
<!-- Add `x` for the ones that is true with you, e.g.: [x] I have ... -->
- [x] I have a question to ask about *how to use ECharts to ...*
- [ ] I have a bug to report
- [x] I have a feature to request, e.g.: *I'd like a new feature that ...*
- [ ] I have a feature to enhance, e.g.: *The current feature should be improved in the way that ...*
- [ ] There's something wrong with the documents
- [ ] Others, or I'm not sure which issue types to choose here
## Issue Details
<!-- Use one sentence to describe what you want and what's wrong. -->
right now, it's not possible to programmatically check what the maximum label value for `yAxis` is (at least there is no documentation showing how to get it.
as shown in the following example, we are trying to determine if some points of different series overlap, and if so, we want to use a bigger `symbolSize` to indicate that 2 points overlap. to do so, the function `dynamicSymbolSize` in my example is created. it works by normalizing the values defined as a `seriesGroup` by determining what the highest value of their corresponding `yAxis` is. this would have worked/will work ONLY IF `yAxis.max` is already predefined or by coincident, if the highest value is also the highest axisLabel. otherwise the normalization doesn't work as wished.
if you check my example, the part marked with `//TODO` is where I need a function like `yAxis.getMaxLabel()` or whatever it's called/is going to be called; or a property which delivers the set value.
### Expected Behavior
<!-- Add screenshots to demo if necessary. -->
the function `yAxis.getMaxLabel()` (or the property...) should deliver the maximum value used for labeling `yAxis`.
### Current Behavior
<!-- Add screenshots to demo if necessary. Otherwise, replace the following line with N/A. -->
I have not found any function/property that does this.
### Online Example
<!-- Please use jsfiddle.net or gallery.echartsjs.com to provide a simplest demo to show the problem. And do not upload zip demos. -->
<!-- THIS IS REQUIRED FOR ALL BUG REPORTS AND QUESTIONS!!! -->
