### Steps to Reproduce

设置chart option（节点y值相同）

```javascript
option = {
series: [
{
type: 'graph',
data: [
{
"name": "A",
"x": 40,
"y": 10
},
{
"name": "B",
"x": 45,
"y": 10
}
],
links: [
{
"source": "A",
"target": "B",
}
],
}
]
};
```

### Current Behavior

## 上述option配置时，关系线出现偏移：
## 节点x值相同时，同样会出现：

## 但是当设置lineStyle(大于1.5)时，关系线位置正常：

### Expected Behavior

关系线位置应该保持正确
