平移时候动态计算Y轴数据范围

- [ ] I have searched the [issues](https://github.com/antvis/f2/issues) of this repository and believe that this is not a duplicate.

### What problem does this feature solve?
以官网蜡烛图-日K为例 https://f2.antv.vision/zh/examples/candlestick/basic#daily

目前官网的例子是把整个图表里的数据进行汇总计算出Y轴总体范围(官网例子 3.00 ~ 6.00), 但是我想实现的是屏幕内数据的范围(官网例子3.00~4.50)

这样图表看起来会更充实一点

### What does the proposed API look like?
有办法动态获取屏幕内数据和设置Y轴数据

Start with the official candlestick daily example linked in the issue and inspect how panning currently determines the Y-axis range. Identify the entry points for accessing data visible on screen and setting the Y-axis range. Done means the chart can dynamically use the visible data range, such as 3.00–4.50 instead of the full 3.00–6.00 range.
