[GitHub] [incubator-echarts] chudur-budur opened a new issue #13302: Can change an option value in a dynamic parallel coordinate plot after rendering for the first time, but not for the next time
chudur-budur opened a new issue #13302:
URL: https://github.com/apache/incubator-echarts/issues/13302
### Version
4.9.0
### Reproduction link
[https://jsfiddle.net/ramgorur/zswuac4b/latest](https://jsfiddle.net/ramgorur/zswuac4b/latest)
### Steps to reproduce
Just follow the [`JSFiddle` link](https://jsfiddle.net/ramgorur/zswuac4b/latest) and run the code. No setup required.
### What is expected?
Once an `option` for a dynamic parallel coordinate plot is set and the plot is rendered, I should be able to change option parameters and the changes should be reflected on the plot on the fly.
### What is actually happening?
I'm trying to make a dynamic parallel coordinate plot, where a user should be able to choose if the lines will be straight or `smooth`. In my case, I have a plot and a toggle button.

The idea is every time when a user clicks the button, the lines of the parallel plot should become smooth from straight, and it should toggle every time when a user clicks it.
<img src="https://i.postimg.cc/d3NXgfcr/Screen-Shot-2020-09-17-at-7-04-03-AM.png" width="400px"/>
The problem is the option values changes only for the first time only, but not on the next click. What I mean, if I make it smooth from straight, next click doesn't turn it back to straight from smooth (or vice-versa). The change in the `option` is done this way:
```javascirpt
function toggleSmooth(){
console.log("Toggling smooth");
// get the current option
option = myChart.getOption();
console.log("Previous myChart.option.series[0].smooth = " + option.series[0].smooth);
// change and set it
option.series[0].smooth = !option.series[0].smooth;
myChart.setOption(option);
// check it again
option = myChart.getOption();
console.log("Current myChart.option.series[0].smooth = " + option.series[0].smooth);
}
```
On the `console.log`, I'm seeing the value `option.series[0].smooth` is changing but the change is not being reflected on the plot.

Not sure if it's a bug or I'm not doing it in a correct way.

It seems to be a bug.
Before it fixed, perhaps we can only work around with `chart.setOption(option, { notMerge: true })`.

Thanks for the follow-up. But still no luck. Appreciate your help.
