xinzai2014 opened a new issue #8143: 关系图，使用dispatchAction showTip显示提示框失效

   为了方便我们能够复现和修复 bug，请遵从下面的规范描述您的问题。

   ### One-line summary [问题简述]
   
为了实现关系图的节点拖拽，使用了graphic组件，graphic层级高，因此节点原有的移入显示tooltip功能失效。需要手动在graphic上添加移入显示tooltip效果，至此发现dispatchAction
 showTip 事件不好用，mousemove可以触发，但是showTip 不能被触发
   
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]:4.0.0
   + Browser version [浏览器类型和版本]:
   + OS Version [操作系统类型和版本]:
   
   ### Expected behaviour [期望结果]
   期望showTip能被触发，或者有其他的方法

                       }

   ```
   ```
   使用了graphic组件
   function initInvisibleGraphic()；
   function initInvisibleGraphic() {
                   // Add shadow circles (which is not visible) to enable drag.
                   myChart.setOption({
                       graphic: echarts.util.map(option.series[0].data, 
function (item, dataIndex) {
                           var tmpPos=myChart.convertToPixel({'seriesIndex': 
0},[item.x,item.y]);
                           //var tmpPos=[item.x+500,item.y];
                           //console.log(dataIndex+":"+item.name+":"+tmpPos);
                           console.log(item);
                           return {
                               type: 'circle',
                               id:dataIndex,
                               position: tmpPos,
                               shape: {
                                   cx: 0,
                                   cy: 0,
                                   r: 20
                               },
                               // silent:true,
                               invisible: true,
                               draggable: true,
                               ondrag: echarts.util.curry(onPointDragging, 
dataIndex),
                               onmousemove: 
echarts.util.curry(showTooltip,item, dataIndex),
                               onclick:echarts.util.curry(fixTooltip),
                               onmouseout: echarts.util.curry(hideTooltip, 
dataIndex),
                               z: 100
                           };
                       })
                   });
                   window.addEventListener('resize', updatePosition);
                   myChart.on('dataZoom', updatePosition);
               }
   function showTooltip(item, dataIndex) {
                   console.log(dataIndex);
                   myChart.dispatchAction({
                       type: 'showTip',
                       dataIndex:dataIndex,
                       seriesIndex:0
                   });
               }
   
   ```
