[GitHub] [echarts] pumpkindev opened a new issue #14935: `echart.convertToPixel({ seriesIndex: 0 }, point)`传入坐标值和返回坐标值相同
pumpkindev opened a new issue #14935:
URL: https://github.com/apache/echarts/issues/14935
### Version
5.0.2
### Steps to reproduce
打印`instance.convertToPixel({ seriesIndex: 0 }, [100,100])`返回值是[100,100]
我通过
```
const series = instance.getModel().getSeriesByIndex(0);
const itemLayouts = series.getData()._itemLayouts;
```
获取到 graph force中node点的坐标，然后进行保存，下次进来渲染的时候直接用保存的坐标值渲染
然而获取到的xy值放入graph中发现比例不对
进而发现`convertToPixel`这个api穿进去任何值，返回出来的值还是原来的值，怀疑是个bug
### What is expected?
希望获取到正确的坐标或者得到获取正确坐标的方式
### What is actually happening?
`instance.convertToPixel({ seriesIndex: 0 }, [100,100])`返回值是[100,100]

我看了一下，graph 用的坐标系是 view, 这个坐标系里点的坐标就是像素信息，所以使用convertToPixel的时候返回的是同样的值

@pumpkindev 在鼠标缩放后值就不一样了。你说的转成 layout: none 会放大应该是因为 echarts 在设置`layout: none`后会自适应到视图大小，这个后面会优化假如是否自适应的配置项

我想要实现的效果是点击后保持emphasis adjacency的效果，发现echart目前并不支持这种操作，所以想点击后获取所有点的坐标，将force图例转换成layout:none图例，自定义逻辑，将不相关点颜色变浅，并且使用force图例的坐标，
发现获取的坐标转换后和转换前相同，导致的效果是点击后图表会整体放大两次
