   Hi, I have read the document as well as the source code. First, the node dataIndex and the edge dataIndex were counted separately. In the code view/Chart.js, I find
   ```
   highlight: function (seriesModel, ecModel, api, payload) {
           toggleHighlight(seriesModel.getData(), payload, 'emphasis');
       }
   ```
   Here getData() can be found in Model/Series.js, I think the possible reason that we can't highlight the edges through dispatchAction now is that getData function will get the node dataIndex but not the edge dataindex.
   
   Could you please help me check it?
