vmihailenco opened a new issue, #19230:
URL: https://github.com/apache/echarts/issues/19230
### What problem does this feature solve?
Currently calling `setOption` causes force graph to update nodes position
which makes any kind of interactivity impossible:
- user hovers over the node
- setOption is called to show the node label
- force layout is triggered and the whole graph is re-arranged
```
{ type: 'graph', layout: 'force' }
```
This behavior can be seen on this
[example](https://echarts.apache.org/examples/en/editor.html?c=graph-force-dynamic)
which constantly adds new nodes. But it is the same if you just show/hide
labels via `setOption`.
### What does the proposed API look like?
Add an option to not update the layout:
```js
echarts.setOption(option, { preserveLayout: true })
```
Some libraries like Cytoscape have a separate API to update the layout when
needed:
```js
const layout = echarts.layout()
layout.run()
```
