### Steps to reproduce
1.点击任意一个graphic的点,查看弹出alert提示
2.拖动一个点较长距离松开查看alert提示
3.拖动任意点非常短距离例如0.1,松开查看alert提示
### What is expected?

极短距离的话感觉你的处理方式是合理的
当前这种避免mouseup，click相关事件冲突的方式应该属于常规方法，应该也没有其他特别好的办法

这个是时间执行顺序问题，简单来说可以用dragstart和dragend来判断一下就解决问题了，上下代码， 具体移动多少，可以自己判断和设置，看看能不能解决你的问题
```
var p = {}
function dragStart(dataIndex, e) {
console.log('dragStart Event');
p.x = e.event.offsetX
p.y = e.event.offsetY
}
function dragEnd(dataIndex, e) {
var x = e.event.offsetX
var y = e.event.offsetY
// 判断移动距离
if(Math.abs(x - p.x) > 50 || Math.abs(y - p.y) > 50) {
console.log('dragEnd Event');
}
}
function PointClick(dataIndex, e, dy) {
console.log('Click Event');
}
```

感谢回复,
问题1 Click额外触发的drag确实可以用这种方法解决.目前也是这样做的.只是感觉有点恶心人.所以用issues提醒下,顺便看看有没希望不用额外的判断进行处理.
问题2 只是极短距离的拖动会额外触发onclick请问有没什么好的方法处理.
目前也是再上面的那个距离判断中加了一个极短距离的位移(!=0),当此的onclick触发无效.
