JasonXDDD opened a new issue #13689:
URL: https://github.com/apache/incubator-echarts/issues/13689
### Version
4.9.0
### Reproduction link
[https://jsfiddle.net/apbxugh5/](https://jsfiddle.net/apbxugh5/)
### Steps to reproduce
I copy https://echarts.apache.org/examples/zh/editor.html?c=dynamic-data2 sample, make it to be areaStyle, add a scatter point to future time, and set `animate: true` on the options.
### What is expected?
I expect it will update area series data smoothly. like: https://app.expertoption.com/
### What is actually happening?
however, its updateAnimate is not work. only push data on the chart without animation.

Hi, @plainheart
I added it, but the same. https://jsfiddle.net/x4wj8nov/
With see carefully, when the 1st series (line chart) before 2nd series ( scatter point ), line chart cannot update data with smoothly animation.
but it is work for data after 2nd series.

Hi, you can have smooth seamless animation by setting animation to `1000ms` duration and `linear` easing. Here is an example

it still look like step by step animation when data update, but ExpertOption look so smooth :(

I think it need an animation from left ( original x,y ) to right ( new x,y )?

This probably is just due to the settings for `animation`.
To specify a better value for update `animation` can make the chart more smooth.
For example,
Set [`animationEasingUpdate`](https://echarts.apache.org/en/option.html#animationEasingUpdate) to `linear` and set a proper value for [`animationDurationUpdate`](https://echarts.apache.org/en/option.html#animationDurationUpdate).
