ayufish edited a comment on issue #7860: 3d 地图，chart.on( 'click', function... ) ，点击地图无反应

   我的版本4.1.0，中国地图，单击事件无效，鼠标双击或者悬浮都能触发
   update:
   查看源代码
   ```js
   else if (name === 'click') {
               if (this._downEl !== this._upEl
                   // Original click event is triggered on the whole canvas element,
                   // including the case that `mousedown` - `mousemove` - `mouseup`,
                   // which should be filtered, otherwise it will bring trouble to
                   // pan and zoom.
                   || !this._downPoint
                   // Arbitrary value
                   || dist(this._downPoint, [event.zrX, event.zrY]) > 4
               ) {
                   return;
               }
               this._downPoint = null;
           }
   ```
   第二个或判断为true，点击被拦截，删掉后两个或判断后单击事件正常
