travis1111 opened a new issue #12163: 如何把坐标写到options 里面去
URL: https://github.com/apache/incubator-echarts/issues/12163
### What problem does this feature solve?
提供方法把力矢量布局后的x y 坐标写到 options 里面去。
我的project 里面需要保存布局好了x y 坐标。这个issue 里面提供了参考：
https://github.com/apache/incubator-echarts/issues/11807
https://github.com/apache/incubator-echarts/blob/master/src/chart/graph/forceLayout.js#L116
现在我能拿到x y 坐标，但是不知道怎么才能把坐标写到options 里面。
谢谢！
### What does the proposed API look like?
暂时没有

可以通过 getOption 获得计算后的坐标吗？

谢谢。
`forceLayout.js` 里面的这里吗？https://github.com/apache/incubator-echarts/blob/da128eb116f47bb10e31bbdc075605be4f3616b8/src/chart/graph/forceLayout.js#L36

@Ovilia 可能我没有说明白。初次调用的时候我不知道布局后的坐标，只能靠echarts 做布局。在源码这里：
https://github.com/apache/incubator-echarts/blob/master/src/chart/graph/forceLayout.js#L116
第116行，当finish是true的时候，只布局完成后的坐标，但是我想知道的是怎么在这个源代码里面把这个布局好以后的坐标传到 option 里面去，这样，我可以把坐标保存下来，下次再显示的时候我就有坐标了。
谢谢

我可以知道动态布局后的坐标，但是我想知道的是怎么把这个布局好以后的坐标传到 option 里面去，这样，我可以把坐标保存下来，下次再显示的时候我就有坐标了。

Set [layout](https://echarts.apache.org/zh/option.html#series-graph.layout) to be `'none'` and pass `x` and `y` in [data](https://echarts.apache.org/zh/option.html#series-graph.data.x).

@travis1111 我说的是你调用的时候设置的，跟源码没关系。看这个例子https://echarts.apache.org/examples/zh/editor.html?c=graph-simple

Thanks
通过这个可以知道
```sh
var series = chart.getModel().getSeriesByIndex(0);
var itemLayouts = series.getData()._itemLayouts;
```
